Well got distracted by my son in the midst of my edit so lost my reply.

But in essence what I said was that it should have had evidence of water overflowing where the tank overflow is then since water has to be displaced somewhere and there would have been bubbles in the tank too, so like I said there is ALWAYS visible symptoms. But good you found it after the fact, now I'd consider what some of the other posters have said and think about reselling it on as you've no idea how long this has been an issue and how much damage it's already done but based on other clues you've provided it sounds like it's been an ongoing issue for possibly some time.

In regards to Crossy's post, it is true that seeing smoke out the back is sometimes not possible from inside the cab which is why you should always have someone in the cab while you watch it from outside when they throttle up.

I see, it was one of those mysterious type leaks with no symptoms whatsoever? Yep...........

Other than the disappearance of water from the radiator.

Good point, I over looked that pretty obvious one.

There was no water in the oil... no oil in the water...

The crack was between an exhaust port and a cooling water duct.

Well there was lot of smoke then.

If the oil was clean that should be a red flag when shopping in a used dealer. But still if there was water in the oil or vice versa it'd be very hard to hide, always check the top of the oil filler cap that's where condensation gathers and there is almost always milky oil there if waters been in the oil or oil floating in the water if the opposite is cracked another thing is the crank case gets over filled so you driving it should have shown some of this at some point .

Well being under the drivers seat and the car being French it's probably a "gas" collector accessory if you catch my drift Clare and yours is overflowing and requires some release. Either that or it's a propellant for the ejector seat leaking.

"Under the rear seat, behind the driver."

French drivers drive from the rear seat now?

Geeezzz seriously??...

and the first thing they do with their pick-up is to modify the engine so as to get a roaring noise and a big black cloud.

Yeah can't figure why all of the fuss about VW, they just did that automatically for their customers without having to pay big money for it and their system was even better as it not only cheated when being tested but it didn't void the warrantee.

My scooter is good value then.the car will have to be second hand when the times come

Yes the worst polluters in the country with the 2 cycle engines and even the 4 stroke don't have emissions so like he said it's about exhaust emissions not engine size so too bad the scooters are exempt especially given their numbers.

My thinking after reading the thread is that you have several possible issues leading up to the fluid loss and that is usually what happens in these cases, it's seldom just one thing. It seems that you may have, as some have said, a blocked radiator as well as having a bad fan clutch, it should have a fair bit of consistent resistance when you spin it with your hand, if it doesn't it needs to be replaced and no they can't be repaired, just a waste of time, need to replace. Couple that with a partially clogged radiator and previously a leaking/weak cap and water was likely backing up and over flowing out the over flow to account for the fluid loss or you'd have noticed some fluid somewhere else by this time. look carefully at where the overflow hose runs out as there is definitely going to be some evidence of it over heating with water stains of rust color if that's the case, repair said items and have another try along with a new thermostat as well as it is also likely too damaged to be working properly.

At first, being such a superstitious lot, they would crap themselves. But when they realised the reality they would just carry on as normal and ignore it.

I'm not sure how many could figure out the technology? So superstitious they may not even give it a second thought immediately thinking it is a Pee? Still I'm surprised that this has come out of Russia as well, not exactly known themselves for their respect or compassion for anyone or their rights themselves. Obviously this tech wouldn't work outside either or anywhere there's the slightest bit of breeze but it's quite interesting and maybe something to build on, the point too is that it is attention grabbing and also begs the question of whether or not it continues to run even if you do park in the space? I know it would disrupt the video but if the sound was still running it'd be getting a lot of unwanted attention from others and the embarrassment of knowing people know you are parking improperly may be enough to deter.

^ They were jammin with your stereo maxed out while repairing your car.. Blew out the speaker no doubt.

Clare, the question always has to be WHY does the head gasket blow? I've only had one head gasket blow in my lifetime and that's even with high mileage and stock racing engines included, that one was on my race and had it's reasons too. There is some reason for all these head rebuilds, likely the previous owners abuse but still that needs to be considered when buying, there are always indications of some sort if one can look carefully enough.

But my point is that just replacing the head gasket and having the head shaved is usually just fixing the end result of other problems that need to be fleshed out first in addition.

Easy.......It's French.

Ok point taken, we no longer allow French cars in the states, most British brands too now that I think about it, (oh sorry I mean Chinese brands) so I guess this anomaly is a kin to the British issues with electrics then? Seems maybe a solution would be for the French to engineer the British electrics and the British the French engines..

These kind of post amuse me. The proposition that US cars are better than European.

If they are so good why are they not sold outside the US? Canada does not count as mostly the US models are made there. OK a few Buicks in China to prove the rule but... Yes one can buy cars from American owned firms like Ford, Opel/Vauxhall (GM) etc but they are not US designed or US built.

French cars are different. Vive la différence.

Back to the head gasket. Likely that the overheating was a leak somewhere else which caused.... or the car has been used for ions with no coolant added to the water, very common here, which resulted in corrosion somewhere which again caused a leak.

Good it was intended to amuse, so the post was a success, as for the rest, well that's just nonsense and besides second only to VW GM was the second car company in China, not just Bu....icks either. A military friend of my missus in China had an old 70's Lincoln he rode around in and loooooved it and had no intentions of ever getting rid of it. No where was it ever suggested that American cars were better either, at least not by me. I've only ever owned a couple of American cars and they were nightmares in my younger years so it left a bad taste in my mouth and later styling was rubbish, now some are very nicely styled but still seem mostly over-priced and under performers to me for what you get in many cases so I opt for German and Japanese these days.

So, I have a new question for all - is it possible to do a head gasket replacement and head shimming/shaving in one day?

That's all it took for them to do my Nissan engine. 2 liter, aluminum block. He just pulled it and had it taken over to a machine shop that has the milling machine.

Thanks Tywais. Its definitely an amazing turnaround, but I guess its possible. When I dropped the car off he seemed to imply that they were next door to the machine shop, and the staff were all super energetic young guys.

The engine did look cleaner, as if they'd been at work on it, though it wasn't a very dirty engine in the first place (not a good sign, I know - the most reliable cars always have the dirtiest engines).

What?? Where you did get THAT chest nut from? Dirty engines reliable? Nonsense, I always keep my engines virtually spotless as I do my own work and hate working on dirty engines plus they run cooler, and it's much easier to notice any fluid leaks sooner and work out where they are. I don't like when the fluids have been changed immediately before I purchase necessarily even if I have to pay after the fact, the fluids tell a massive story, but clean engine? No way! To me it shows the car has been taken care of and not run through the ringer, if it looks terrible on the outside you can only imagine what the inside looks like and it isn't pretty.

No, Warp, the car looks quite good - there are several pictures of the Peugeot in another thread: http://www.thaivisa.com/forum/topic/849455-considering-peugeot-405-however-weak-air-con/?p=9785007

So, I have a new question for all - is it possible to do a head gasket replacement and head shimming/shaving in one day? That's what my new mechanic claims he's done. I went by today and he said its all finished except he's going to replace one of the electric fan motors tomorrow, should be done by 4 pm. He said the head was 4,500, and the electric motor should be 2,000.

Should I believe him that he actually did the head that fast? It took my old mechanic two weeks for the same work on my Honda!

Sure it's possible usually the machine work is what holds up the job but if he has a source that can do it quickly no problem, only an hour or 2 for that job and then the install, but for me it'd be pushing it, I don't like to push jobs though that quickly but at least you know they won't have it done in a day and tell you it'll take 3 or 4 days while they use it to run errands, although that is some times done for test driving more then a quick run around the block.

But now you're saying that there actually was a fan not operating? Ut oh! Especially with A/C running.

BTW Clare I saw the pics in the other thread, you sure took the wind out of the piss take though.

I got a BUNCH of tar on mine a while back. A diesel fuel soaked rag and a little elbow grease got it all off. Diesel is a very gentle solvent, didn't damage the paint.

Hope you wore gloves, diesel is a nasty carcinogen.

OP said:

Next question, post removal, I would like to polish/wax the whole car

Yah yah.. But he still seemed uncertain and indecisive so I gave him another little push.. No harm no foul .

^Ooops, familiar story, I've not been keeping up, now I'm caught up ... I was in the midst of relocation in 2012 had far more important matters of my own to tend.

Just remembered Clare, your Peugeot doesn't look like this one does it?

This was my neighbor during the floods, he jacked it up but as you can see the water line was still up on it several inches definitely flooding the interior and when the trucks and cars came by it was worse with the wake until the rafts came out finally instead.. Come to think of it one thing that was eerie during the floods was the silence, no loud trucks running up and down the streets with loud speakers blaring.

WD-40.................................................................

Britain still leads the way in London Black Cab production!!

There is that...

CQ is my memory failing me or didn't we go through all this head business with you before on another of your junks ... anyway rain today to something to read while sitting having my morning voffee

His Honda. De ja vous.

"we no longer allow French cars in the states, most British brands too..."

Bugattis are sold in US aren't they? They're French.

Rolls Royce, Bentley, Aston Martin, McLaren, Lotus, Land Rover, Jaguar are sold in the US.

I know foreign companies own these names but they are still considered to be British just as Chrysler, owned by Fiat, is considered to be a US company.

There's always one who has take everything literally, but none of the models you mention are French, Chrysler is a different example altogether but now that FIAT owns it it is supporting them through the European slide, the Bugatti's for example are now VW group owned but were never French they were Italian by an Italian designer who lived in France for a time after he sold out. All the mentioned British brands are currently and long term have been owned by other nationalities. Now none of that has anything to do with the joke ..

Underlying causes have all been listed already in your previous thread with the Honda, a motor is motor beyond a bit of personal engineering differences by different manufacturers.

Sorry, I don't recall those underlying causes, will have a look... do you mean the fan, thermostat, or the water pump being broken in the past? That's what I find in the old thread. But obviously those initial causes have been fixed long since.. the fans spin, I've seen them myself, and I doubt the water pump could have been non-functional for the 3 weeks I drove the car before this problem arose. The point I'm making is, what difference does it make what caused the car to overheat many moons ago, if the residual problem is a - as is often the case - a warped head, or as is more rarely the case, a cracked block? Or are you saying that the problem may be that the system needs to be 'bled' - that there is air in it? Again I don't see how it ran for weeks like that... We could see by looking that there are zero water leaks from the hoses, radiator, etc. That leaves the thermostat - maybe this is just a bad thermostat?

I have to admit I thought it a bit strange that the mechanics were so quick to diagnose the head gasket, without checking the thermostat. Perhaps its just that in their experience the head's the cause 90% of the time, so they just jump to that conclusion.

No, no bleeding necessary, just cumulative damage from either a previous problem or a current one added onto the previous issues, hard to tell from this vantage point. But that's my point, the head should NOT be the problem 90% of the time. I'd say that more then 90% of the time something else began the snow ball that eventually leads to the head gasket blowing.

Clare, the question always has to be WHY does the head gasket blow? I've only had one head gasket blow in my lifetime and that's even with high mileage and stock racing engines included, that one was on my race and had it's reasons too.

Well British cars are or were as we have none (mass production) left even worse than the French for over heating and gasket failure, but it would spoil the incredibly witty one liner.

Well what really spoiled the incredible witty one liner was that I forgot about the Indian owned Jaguars, Range Rovers and the German owned Rolls, Mini's, Bently's and Mclaren's that are still sold in the US market .
