Isuzu Engine Needs Overhaul.

[katom]

hi guys apperently I have a problem with the engine.

the engine bring some oil to the point where air suppose to be.

The isuzu guys cleaned the engine and pipes but said that I need to be carefull and better do "Overhaul".

How much is this suppose to be? any other effective solution? (d-max 3.0" 04).

thanks.

?

I'd be surprised if it needed an overhaul being a 2004 model, how many kms does it have? Mines 2004 3.0 also with just over 100,000 km on it and runs better now than when I got it.

Can you be more specific about the oil? Does it use oil and need topping up between changes?

[apetley]

Do you mean that your getting oil blown into your airfilter?

Not sure if it applies to Isuzu but in the past I have had a similar problem with the topend which needed some attention.

[Thaiboxer]

My brother-in-law had the D4D engine on his 2001 Hilux Tiger overhauled. Total cost was 46,000 Baht. This included replacing pistons, perhaps the head and also the valve train. I don't know all the details, but now the thing runs like new.

[katom]

ok I attach picture of isuzu engine to show what happand and the isuzu said.

*the red marks show where the oil went,the isuzu claim that in this pipes usualy suppose to be AIR and not OIL.

What happand is like this:

From the pipe on the left side was throwing oil on the down and left side area (leaking), I found it and checked the engine-oil.and left little bit.

I drove to Isuzu to let them check it out.

They started the engine and take the oil-check (the Blue sign on the picture) little bit up and there was some smoke that I think its because left little bit oil.

They claim the engine had "accedint already" because where the air need to go the oil go ALSO.

So..they said need overhaul, I said wait.first open see what happand.the opened,cleaned the pipes (red signes),also opened the engine and changed 2 cylinders(injektors) for new for free and changed new oil.

After that I checked the oul-check (Blue sign on picture) and there was no smoke.

Anyway they say: can run the car but check oil more often and Anyway one day need to do Overhaul.

I know nothing about mechanical thing but I want your opinion about what really happand..

Thanks guys.

A friend of mine has 285,000 kilometers on his Isuzu and the engine still runs great and has never been touched.

While the engine is warm, take out the oil filler cap and if there is a lot of smoky smelly air coming out (called blow by) the engine will likely need an overhaul. If there is no air coming out, they problem is elsewhere.

[katom]

take out the oil filler cap?? not the oil-check thing?

Is it really ok to do so? (I afraid the oil will jump to my face or something.. ).

From what I described and show on picture what do you thing the situation is?

[katom]

I read some article suggest that it might be the PCV VALVE.. where is it located?

[Thaiboxer]

Hopefully it's the PCV (Positive Crankcase Ventilation) valve, as that would be preferable to an engine overhaul. The PCV valve is supposed to take the air in the crankcase and send it into the combustion chamber to be burned. A little bit of "blowby" as GaryA called it is ok, it can occur at high speeds as the piston rings may flutter or float so they don't seal off the combustion chamber (top of cylinder) completely.

However, if the rings and/or cylinders are worn, oil from the lubricating system actually squeezes around the pistons where it is burned in the combustion chamber. This what generally causes an engine to burn oil, which will cause your oil dipstick to read low fairly often. A very easy thing to look for is smoky, blueish exhaust coming from the tailpipe after the engine is warm. If you see this, you will probably need to at least replace the piston rings and possible rebore the cylinders and install oversized pistons/rings...major machine shop work.

Tomorrow I will look for the "Bluish exhaust from the tailpipe" (you mean behind the car..right ?).

What I can tell you is that today I checked the "oil-check"(where the engine located of course..) and took it little bit up same the isuzu did to show me..and yes..again,have some smoke from that point (oil-check).

So, do you think "Over Haul" or no?

The thai says that yes,have problem but can use the engine but always check if miss oil and then put oil,check and refill whenever needed untill the engine die or something..

Another BIG question-

whats better?

1) buy second hand engine (which I dont know what he has been throw..) = 12K baht.

2) Over-Haul my own engine for something like 15-18K baht.

3) wait untill the engine will die and then choose option 1 ?

questions..lots of questions..

Take it to another Isuzu dealer and get a second check up. Unless the engine has been abused, it should not need any major repairs.

thanks.

If you mean the air filter is getting engine oil into it ,it sounds like you have crankcase compression, minimum of a set of rings i fear, but get at least 3 quotes for the work,

Have you ever overheated it ?

[katom]

BTW: the isuzu did installed an over-pass small pipes with some box/small gallon that will collect the oil (whatever this means).

But again,just to minimize that damage until I'll decide what to do...

[katom]

over heated? I think just the last time that I checked with the "dipsteek" to check oil and saw left little bit oil.. but then I straigh away went to isuzu.

I usually change oil and I even changed to untifreezing water lately just to AVOID PROBLEMS.. funny,ha? then I've got another thing..

[Thaiboxer]

Lack of engine oil can cause overheating although overheating is usually caused by other things. This is a big issue with turbo engines as they're very sensitive to oil changes. You MUST change the oil according to your owner's manual and to be safe, I'd change it before then. Always use synthetic oil with a turbo engine. Turbo engines run much hotter than non-turbo engines and that oil will basically cook inside the engine and turn into sludge and then dust.

Overheating is often caused by coolant leaks...the antifreeze (green liquid) and water can leak out of the engine, radiator, water pump and any rubber hoses. Also, there can be an internal (inside) leak in the engine from a cracked cylinder head or block and/or a blown head gasket. If you see oil or milky colored stuff in the radiator, there is an internal leak. Also, white smoke coming out of the exhaust after the engine is warm means there is an internal leak...water/antifreeze are getting into the engine where it gets burned and turns into white smoke.

Whatever you do, find out as much as you can about your truck and get other quotes as another poster said. Good luck!

[katom]

apparently there is no escape from overhaul.. or whatever u call it when need to change the rings..

just update thats all.

cost: 15-18K baht max.

[katom]

so second hand engine or overhaul? what do u think?

[Thaiboxer]

If your vehicle is only 4 years old, and if the max price for an overhaul is 18K Baht, I'd say go for it! A second hand engine could cost more than that, and you may or may not know who owned it or what it was used for (hauling heavy stuff or just plain driving). Just make sure that the cylinders don't need to be rebored by a machine shop. If they do, new rings won't cure the problem. This happened to a Honda Prelude I owned many years ago.

[INTJ]

I'd like to know where you can get a 3.0 Isuzu commonrail diesel engine for 12,000 baht.

Grab me a couple while you're there.

[katom]

well I'm not going to change it now.maybe they just tried to make money on me..I dont know you tell me.

more then 1000 km and I checked oil not miss a bit of engine oil..

[Thaiboxer]

It sounds like the guys tried to pull a fast one on you. The same thing happens in the USA; some bad mechanics will rebuild or replace your whole transmission instead of doing a minor repair that would cost a lot less.

[katom]

ok but I did saw the place where the air need to be with oil.. (look at the picture on the RED color) I even dont know if need to be air only without oil..u tell me please.

What about the thing with the "dipsteek" -check-oil ,when turn-on the engine and take it little bit up have little-bit smoke, the isuzu claim that when see it it means BIG problem.

I'm just trying to understand my engine situation as I think they tried to trick me...but maybe the situation is going to be BAD..
