Would A Worn Out Clutch Really Cause The Loss Of A Lot Of Power?

[lostinisaan]

Sawasdee khrap,

I had to drive to Ubon yesterday and found out that my engine has lost a lot of its performance in form of power. Trying to do more than 110 km/h was almost impossible, I've got a Mitsubishi Strada, L 200 with the 2.8 liter engine.

I remember doing 160 km/h without a problem, but it seems that something is preventing the engine to lose a lot of power to put on the rear wheels.

Currently, I'm sitting at Mitsubishi Sisaket and the head mechanic told me that my clutch would be worn out. I do understand how a clutch's working, but haven't had such circumstances yet. And I had many cars in my life before.

I can hardly make more than 3,000 RPM in fourth and fith gear, got the feeling that I'm driving a Kubota...

The reason why I'm asking you guys is that a new clutch, incl. pressure plate and bearrning will be around 10 K+ and I don't wanna spend so much money if it isn't the problem.

Advice from some specialists would be deeply appreciated, as I'll have to make the decision now/ today, because I'm already at Mitsu and they've got not many cars to fix.

Thanks a lot in advance for any useful input. Khop Khun La Lai....

As I'm sure you know, the main symptom of a worn clutch is slip, put down your foot, engine speed increases, road speed does not.

Failure to rev in high gear is (IMHO) unlikely to be a worn clutch.

Could be a blocked air filter (look there first, easy fix), dead turbo, worn engine (bores / rings) or something in the fuel system (bad injectors).

[jvs]

If your clutch would be really bad,you would have no forward power but as soon as you hit the pedal your rpms would go up because of not much load on the engine because the clutch would slip.

When your truck is out of gear can you get full refs?Is the airfilter clean?How many km on the truck?Brakes dragging?Fuel supply?

If anything is dragging you would create friction ,a lot of heat and smell.(handbrake on)?

Is it running on all four cilinders?

Could be many things but i doubt very much it is the clutch,it would give you the very distinctive burned clutch smell.

[Songhua]

Turbo? Check hoses/clamp points for splits/leaks.

[cumgranosalum]

I would say absolutely not

the clutch is the "interface" between the engine and the drive chain......the only way you'd loose SPEED is through clutch slip....in that case you'd see/hear the engine revving abnormally as the clutch struggled to lock shut. It is also very likely there would be an unpleasant smell of burning clutch.

The old Mitsubishi L200 is great, simple and well built vehicle - although it will achieve quite a high top speed, I'd not expect 160 out of it...140 is more likely. however the acceleration etc on this naturally aspirated diesel is NOT very lively.........

If your perception of lack of performance is real, then as above I'd check air filters first and even the fuel supply,filters, lines, diesel pump etc.

the air filter is easy.....just take it out and drive about - see if it goes quicker......

i get the impression the vehicle has either been standing for some time or not used much....it is then quite possible that the fuel lines have gradually become filled with crap and no-one would notice.....or better still ants or mice living in the air filter???

[cumgranosalum]

If this is the old Mitsu Strada L200, it is naturally aspirated.

I would also question why one would look at the potentially most expensive part first when it may be a far simpler cause........

perhaps the OP could give more details about the model and year.......

[Pomthai]

Almost certainly not clutch. Most likely culprit is clogged air filter (usually a lot of black smoke as well) secondly a clogged fuel filter resulting in fuel starvation.

They did do a 2.8 VGS turbo on them so it could be turbo or inlet piping boost leak but I'd expect some smoke with that too because its after the MAF sensor. If it has a inlet MAP sensor perhaps no smoke, but doubtful it has one of them on those older engines.

From a rotating equipment maintenance engineer standpoint you're right on track. There is nothing wrong with the clutch.

For gasoline engines (particularly the ones before E-10 the problem is the fuel system is closing up starving the engine for fuel caused by swelling of the seals and/or flex lines in the system. The alcohol in the gasohol fuel does that, in particular now that oil companies are stuck which higher price than crude oil gasoline are throwing more of the alcohol in to the mix by far exceeding E-20 (meaning 20% alcohol).

Note: a while ago the oil companies requested the Gov. to be allowed to stop mixing and go back to straight 91 and 95 gasoline. The Gov. said, NO you made the supply contract and have to stick with that contract.

Have a nice day, Dr. Frans

i think there is a problem; we don't know exactly what model it is...i've assumed that it is a naturally aspirated Diesel.....not that it really makes any difference to the first basic checks one needs to make.

[lostinisaan]

I'm sorry for not getting back earlier. The clutch is already changed, might take another hour.

I have 278,000 km on the clock and it's still the first/(was) clutch. Just saw the foreman taking it out for a testdrive.

Holy crap, didn't think about Trans' advice, as it could be shitty Diesel oil, the filter's always serviced by me.

I think I've screwed myself and will have to pay my own stupidity with hard earned cash. The one guy told me that it would be to 100 % the clutch.

Will tell you if the problem's gone. I told my wife yesterday that I think it's mixed Diesel oil, from a little gas station ,happens from time to time that the Diesel gets mixed up.

I should have known better. The only positive thing seems to be the 10 %, I receive as an old ( stupid) customer. A total sum of 9,000 baht...

Just saw the chef mechanic coming back from a test drive and drive right back to check the engine? Now I wanna cry, kill somebody, or rape the chef mechanic and foreman's daughters.

I've got the feeling that it's the Diesel system, air coming in somewhere, or just shitty Diesel oil, mixed with water.

There's no black/ white smoke coming out of the exhaust system. Have to look for a rope now. Or rape? shit.

My own fault, should have waited, the old clutch was still okay for another 40-60 K. Holy buffalo shit

Thanks to all you guys, I have to admit that I'm stupid, was just asking the foreman, they sent me back to have another coffee and actually try to make the troubleshooting.

P.S. The truck's 16, or 17 years old, with the 2.8 liter engine. It ran fine, 160 km/h wasn't a problem before. I didn't drive longer distances for quite a while,only to school and back, okay I had the feeling for a few days that something was wrong, but finally found out that something's wrong when I drove to Ubon yesterday.

Cheers.

Clutch didn't fix it, clutch doesn't get paid for - simple.

If they want it back they can take it out.

It easily did 160 km/h before. Please read my post, seems to be my own fault not to wait and read these posts.Old clutch was still okay for 50 K+.

I could start crying, killing, etc.....but it's finally my own fault. And the joke is that the problem isn't found yet. God.....

[lostinisaan]

Thanks Crossy, exactly what I was thinking about. Why should I pay almost 10 K if this wasn't the problem?

I'll have to let them know now how I feel. I feel so stupid like I was shitting my own pants.

[Crossy]

Have they looked at the air and fuel filters yet?

Well after a quarter of a million KMs, it probably needed a new clutch anyway....but I doubt that this was the problem.

Black smoke is not usually a problem as such - it means the fuel isn't being burned up properly in the engine. Blue smoke is oil and worrying white smoke means water is getting from cooling system into the combustion chamber, and probably elsewhere....that would be an immediate worry.

I will continue to assume it is a naturally aspirated diesel.

Diesel engines increase by increasing the amount of fuel going into them - the amount of air should stay the same........

If there is not enough fuel getting through, you won't get smoke - just lack of power.

Dirty fuel is unlikely to make it to the combustion chamber but it can clog/flood filters and interfere/restrict with the supply of fuel from the tank to the engine, this will result in lack of power.

Air is required to make the fuel explode - this is "sucked" in through the air filter and compressed in the engine....a lack of air in diesel tends to result not just in lack of power but an increase in black smoke as there isn't enough hot air to fully ignite all the diesel.

do let us know how you get on.

BTW - if the car is performing correctly now, don't assume it was the clutch after all....unless you have clutch slip, that is not the answer.

you'll have to find out what else they did while they were changing the clutch.

are you at an "official" Mitsubishi dealdership?

[Crossy]

Well after a quarter of a million KMs, it probably needed a new clutch anyway....but I doubt that this was the problem.

Agreed, my first clutch in the ranger lasted about 150k, it still had meat on it but they changed it when they replaced the dual-mass flywheel.

You might be right, but I insist that they put my old clutch in !!! Just had a chat with the manager and the chef mechanic, who're pretty much speechless.

I can be happy that I'm able to communicate in their language, just told them that I first told him that I do not think that it's the clutch. The manager, who made the test drive said it's 100 % the clutch, which finally led me to the decision to say change it then.

Mitsubishi Sisaket redid the whole car after a serious accident, including welding the frame, etc...because the first little garage in Kantharalak had messed it up.

After the whole car was redone the second time by Mitsu Sikaet, I got it back after 15 months and wanted to freak out when I went for an alignment.

Four ball joints were seriously out of order, a dangerous situation. When I was asking the foreman why they didn't do it, he told me that nobody gave the order to do so.

.That waqs the time when I really lost my temper, told him if I'd make such a shitty job as a teacher, they'd kick me out immediately. That was the only language they understood and things went much better from that time on and they fixed all.

So there's a history and I'm waiting for their response, already told them that I want my old clutch back in ( hoping that they might rethink their mistake)

and that I'm wondering why nobody even checked air filter, Diesel filter, etc?

The manager of the garage ( who made a test drive with me), told me it's the clutch to 100 %, that's why I gave my yes. But even considering that I'll need a new one after about 40 - 70 K

Now I decided that I want my old clutch back in and I'm wondering what they do. Unfortunately, my only free day's wasted at Mitsubishi and it seems that they still don't have a clue what's wrong.

Misses is waiting at home, angry,. because we wanted to go swimming. I'm on 180 and I will do all to win the game.

Talking to the chef mechanic, he understood my point that I'm not going to pay 9 K for something that wasn't the cause of the problem. Please put my old one back in...lol

I made them lose face by asking them why they din't even check the filter system(s) and they finally looked at each other and understood that they made something wrong.

Oh boy, the car's still as it was when I arrived this morning at 8 am. No idea what will happen, the battle has just started.......

Dual mass seem to be much shorter lived too.....

Nope. But they do now, because I told them to..................

P.S. I've been here since 8 am.....

[lostinisaan]

I see some movements. The youngish guy who changed my clutch just lifted the truck up and it looks like I get my old clutch back in.

Time to eat some more Mama soups and have another coffee, some take home ovaltine, etc...lol

Yep, watching the guy through the window, he's taking my gear box out. Holy buffalo dung.

Life's sometimes really wonderful. Tomorrow I'll have Fiber Glass Internet, just wondering how smooth that will go.

Okay, Jay JennJenn.

You have a new clutch! Don't tell them to take it out! Leave it in for free!

Then find out what the problem really was. mkae sure everyone agrees - I think they'd much rather leave it in than spend another few hours taking it out.

At the end of the day, it's up to them how much work, necessary or not, they do before they resolve the problem with your car.

As you are at a Mitsu dealer - you need to be aware that Mitsu HQ have a team of "roving" mechanics and engineers who you can call in to resolve disputes like this this.

I had seriously dangerous steering problems with my Strada and Mitsu Chonburi tried to tell me there was nothing wrong....eventually it was repaired free by this team in a garage of my choice.

you may need to get a diagnosis from an independant (reputable) mechanic as what the problem really is.

Thanks for the flowers !! I've tried my best, but they really take it out instead telling me that they'd made a mistake. The irony is that people on an online forum found out that the clutch wasn't the cause of the loss of power.

As I told my wife yesterday that there might be some low quality Diesel oil in, or a faulty/dirty Diesel filter and most of you guys said the same, it makes these mechanics to absolute idiots.

The best will be to take it to Sisaket Diesel tomorrow morning, let them do a check and I'm sure that they find out what's wrong without an overhaul of the Diesel pump or new injectors.

I'm even so pissed that I don't even want them to check the Diesel filter, ( what I'd suggested) and the tubes, eventually vacuum leaks,etc..

Gear box is out, thought about it and might tell them to put only a new clutch disk in and a new bearing. But then they've got the right (and will) charge a lot more than it would normally be.Maybe the youngish mechanic guy's THE gearbox specialist in the near future through me?

Better let it go and forget a whole day at their shop. But I haven't spoken to the main manager yet. Was maybe a big mistake and I would still have the new clutch in, without paying for it.

Another day in paradise. Heads up.

P.S. Good luck that I had my notebook with me as I was on my way to work, but then decided that my car felt sick.....

At least I can write some rubbish here and might get a posting holiday, who knows? Would perfectly fit.

The moral of the story is that telling people lies that I'd be sick ended up in a sick story and a wasted day at Mitsubishi.

B.T.W, There's a time where I made troubleshooting for American/ European/ British and Japanese cars, but that was about electronic/ electrical issues, where garages couldn't find the problem.

That really makes me feel very stupid to believe a guy telling me that my clutch would be the problem.

But is' definitely worth to send the Mitsubishi headwaters a detailed e-mail how good their folks really is and point out that they should hire some TVF expert/expats?

The gearbox is back in, the guy "only has to attach" the drive shaft and a bunch of screws. Just wondering how many will be left? Gosshhhh.

I might end up and pay a tremendous sum for all the coffee, WIFI and Mama soup..................

SIMPLE:

Worn out clutch will NOT MAKE YOU LOOSE ANY ENGINE POWER.

WORN OUT CLUTCH will simply not transmit the power/torque to your drive train....as it slips! (so even if you had 1000hp....with a slipping clutch your car would feel perhaps 300hp) depending on the wear.

If your clutch is slipping but not worn heavily, you could release the throttle and reapply it...this would assist the clutch to "grab" but again it wont last long.

NOTE----while you also dont loose engine power, you will loose "load" created by clutch grabbing so without the load you will no doubt have less boost, less power. regardless it is all wasted as you cannot put the power down.

a clutch friction plate is very cheap, get a good one. also i suggest to look at an upgraded disk......

for the cover...if it is not damaged then no need to replace it....by replacing it with a sport type (OTOP) thai made your clutch will be very heavy....the only way is to play with the throw out bearing clearance to assist the heavy feel.

[lostinisaan]

At least I can write some rubbish here and might get a posting holiday, who knows? Would perfectly fit.

It can be arranged...

Thanks a lot. Not now, please. Tomorrow will be the new Internet story. TOT promised to connect me to Fiber 20 Megs......

Already paid 2,100 baht, will have twice as much download speed and 20 times more upload speed.

But I might not be able to be there, seems that I'll have to spend a night at Mitsubishi, you should see the eye candies, worth to sleep with. aeehh here.

Oh my Buddha, at home is an angry wife, already wearing her bikini,waiting for me to go swimming.

There's a high possibility that my voice's changing a bit soon.

[philipm]

relating to power loss....

sorry i didnt read the forum completely before answering.

your symptom sounds more like a injector/fuel pump problem and could also be Diesel particular filter (DPF) or in Thai known as (SOLAR) ....simple terms mean the diesel fuel filter.

it is common that they get clogged and should be replaced frequently.

that said, it could also be related to EGR system clogging up your intercooler pipes, intercooler and intake manifold......

LOOK out for excessive black smoke and the truck runs like shit or not.

like alot of older trucks you see on the road, you see them pour black smoke but without any real momentum.

Do you feel the truck has power and then all of sudden drops at higher rpm with more throttle?

or is it consistent loss of power.

And Yep, I do see many trucks and cars, almost every day, where black, sometimes blue and even white smoke's coming out of the exhaust system.

[Pdaz]

It's done how many Km's ? 200+ and you want them to put your old clutch back in ? hahahahah For less than 300 bucks ? hahahah.. It two weeks time when your old clutch gives up you'll be back... and you won't get a 10% discount then.. Only hope they don't bugger something else just to spite you.. You be bette off leaving the new clutch in and negotiating a larger discount.

First rule of fault finding... Check the simple/cheap stuff first.. Second rule... never listen to a Thai mechanic... hahahaah
