Had my turbo let go just over a month ago so fitted another second hand pd130. Last weekend then was out an about in the car and something has gone again. There was a loss of power again and a big cloud if White smoke. So I had a look at the car today, checked all the intercooler pipes were connected properly and there was no oil in the pipes unlike last time. There is also a small amount of oil coming out of the exhaust. There is no oil light coming up but when I checked the oil level it's not even registering. There is no oil anywhere around turbo area. There is also no smoke until u press the accelerator.

Any ideas?

white smoke could also be unburnt diesel if there is lack of compression, you would tell by the smell, can you get near the back and another person rev the car gently to generate the white smoke? or is it only when under load on the road?

the smell will tell you if it is oil or unburnt diesel

When you changed turbo, did you empty exhaust of oil from whenold turbo went?

yes will try that and see if i can smell unburnt diesel

no i only cleaned the intercooler piping and intercooler, there was still some oil being spat out after i refitted the new turbo only under load tho ?? was told the oil would clear itself eventually

If its white as opposed to blue smoke, don't you want to be looking at water than oil? Just a guess but haven't got any experience with Diesels...

Water seems fine, engine temps are normal.

What else can I check?

When my turbert popped I had a fair amount of white smoke coming from the crankcase breather ("elephant hosed")... not saying it's that, but I guess it would be easy enough to check. Unclip it from the air intake and block off the air intake hole temporarily... see if your white smoke starts coming out of that little stubby pipe rather than your exhaust?

It's definately White smoke, there is a small amount of oil coming out of the exhaust and what looks like water? There is no smoke coming out of the breather pipe. Also had the misses to press the accelerator slightly and I can smell unburnt diesel. She also sounds a little bit rougher than usual, more of a deeper note ?

Any idean? Head gasket possibly?

Anyone?

I'm not mechanically minded enough to help more really, sorry :(

Can you hear the turbo spooling up still? It hasn't just popped again for some reason...?

im no mechanic...

black smoke, unburnt fuel

blue smoke, oil

white smoke, water ie head gasket or something

why would the compression make a difference to whether the unburnt fuel is either black or white? surely unburnt fuel is just that, unburnt fuel? didnt really think you could get it in different forms lol

geniune questions btw not criticism

Yeah thems the guidelines I know for smoke colours

However, when mine popped I don't remember seeing the 'plumes of black smoke' that's so common. I only remember seeing white smoke appearing from my crank case breather!

So if it is the head gasket then is there usually a loss of power?

When it did happen it was as if the turbo had popped...

if you can smell unburnt diesel and have white smoke i would get the compression tested, being a diesel not all garages can do it due to the higher compression ratios of a diesel engine compared to a petrol

can be many things, pistons (usually get pressure built up in the crank case with this), head gasket (check water in the header tank for oil contamination or mayonaise on the oil filler cap) or from what you are indicating above possible more likely a valve problems (wet compression test will tell if it is pistons or valves)

as to the post few above about white smoke and unburnt diesel, the process in a diesel is that the air when it is compressed heats up to a temperature where the finely atomised diesel is injected it ignites immediately, if the pressure is not high enough due to a compression leak the temperature in the combustion chamber is not sufficient and the diesel vapour is ejected out the exhaust as a white smoke/vapour with the smell of diesel you get at the filling station. you can see this in a diesel if you have a problem with the glowplugs / preheat system on a cold morning

sounds like turbo seals have blown on exhaust side of turbo. no oil in engine usually means its being pushed through exhaust.

my dads audi pumped white smoke out of exhaust when turbo died and oil level emptied its self.

dont drive it at all if it can be helped the more you drive it the less oil the engine has to survive.

as above could be head gasket but they are pretty tough on the vag diesels. if it was head gasket and you had no oil on the dipstick the only place it can go is into the water so unless you got brown sludge in header tank or usually mayo syhptoms on oil cap my money is on the turbo............... sorry

did you check for play on the turbo shaft before fitting the new turbo?

as its blown 2 in a short space of time id be looking at other areas to be responsible for your turbo failures

did you change the oil feed and return pipe when you fitted the new turbo?

yes checked for play in shaft before new turbo was fitted, had to buy new oil feed as original one had a hole in it which is why i think the last one went.

No signs of any gunk or mayo type in oil cap.

i was told when i bought the car that its running 2bar on standard turbo so thats why i think its going. I have all the other mods to help but obviously the standard turbo cat take the pressure. plan was to get the boost turned down.

sorry to say it but sounds like a bad re-map think max pressure turbo can safely take is around 1.6-1.7ish so no wonder its blowing turbos.

will get a garage to have a look at it to see exactly what has gone :no:

get the map changed too, 2bar is faar to much for stock kkk 130 as said above, 1.6 bar max imho
