Blue Smoke After High Speeds

[SpannerWrench]

 

I've recntly purchased a 2000 (W) Galaxy TDi, 135k recently had new Turbo and cambelt fitted. I'm very pleased with it but have noticed blue smoke after higher speeds (70-75mph) It then smokes pretty much all the time after that. I have read it may be piston rings but to check the air filters and change oil for a part synthetic rather than full synthetic which I have done. I noticed when changing the oil that there seems to be oil residue around the sump and bottom of the engine. Some say its terminal others say fixable. I dont claim to know anything about engines but my father-in-law is a bit of a petrol head and was wondering if it was something we could do ourselves. It also started juddering in low revs the other day, any idea what that is??

 

Just need an idea of whether to keep it or try and get rid before it costs me a fortune! :huh:

Hi Firstly welcome to the site Spannerwrench.

was the turbo changed to cure the smoking? also incorrect timing will cause smoke, was the engine smoking before these changes.

Valve stem seals can also cause this.

When you rev the engine up does it sound smooth ie, no misfire does it tickover evenly, the juddering may not be engine related, is it manual or automatic?

Thanks for the rapid response, in answer to your questions:

 

Turbo: Dont know, I believe it was changed as it had failed and the cambelt was done at the same time. The guy I bought it off was a trader and said he had been going to Portsmouth in it for the the last few weeks, he didn't mention the smoke (surprisingly enough!!)

Engine Sound: No misfires and sounds smooth. It ticks over evenly.

Juddering: Auto gearbox.

 

I took it for a spin last night and didn't notice the smoke although I didnt take it out for long. I gave it a good boot (which usually starts the smoking) and saw none but it could do with a longer run I think. I'll try again tonight.

 

You mentioned stem seals? Is that something thats gonna cost or is it a fairly simple replacement?

 

Thanks again. :(

Hi again

Just had a thought am assuming the smoke is coming out the exhaust at the rear of vehicle and not out of the booster heater exhaust located under n/s rear passenger door area, if it is thats an easier fix.

Booster heater only operates at temperatures below about 10deg c thats why if it is that you wouldn't see smoke all the time.

If booster is ok then read on.

 

Forgot to ask before does it use a lot of engine oil? also run the engine with the oil filler cap removed can you see a lot of vapor coming out also place palm of your hand over the filler can you feel pressure on your hand, if yes to any of these will involve major strip down.

Valve stem seals are located on the cylinder head which would involve removal of the head and valves, if your taking head off may as well drop sump and remove pistons to replace rings, all this is assuming wear limits are within the specification.

 

Personally I would be inclined to take back to where you got it and get your money back as it could be you have a slipping transmission aswell. :(

Thanks again for the advice, I'll try what you said and let you know the outcome. Prognosis doesn't look good tho. :(

Check for oil leaks - around turbo - particularly the oil feed pipe. Could be leaking onto hot exhaust and causing smoke and the residue you observe.

 

Turbo could be faulty - internal seals

 

Other than that - I'd say its probably f****d. Engine strip down and rebuild if you are into DIY. :(
