hi guys basically ive had my car full hybridized with new parts ect, now im geting a bit of smoke on idle ect , first thought piston rings , now been told it could be valve stem seals also car feels a little under power i no its not the turbo as its coverd 1500 miles so in good nick. checked my oil this morning and:shrug::cry: emty so its burning oil big time. i have a spare engine anyway but if its valve stem seals i can get away with just using the head instead the full block . can anyone shed some light anyone sufferd these problems . many thanks

have suffered same problems on other cars, not yet on my cupra(touchwood). could possibly be stem seals (wont necessarily be blue smoke emitted from exhaust, unless its real bad), to eliminate rings you could have a compression check done.

same symptom as you, mines smokes heavy at idle and if i idle more 3seconds and pull off it give puff smoke out...turbo been replaced 3times....catch can fitted.....
still no luck...drinks a litre of oil a month...lol
rebuild time for me...was told it could piston oil rings too...but i doubt it as i have high compression on all 4 cylinders.

Are you gettin slight misfire on idle?

Things to check..

Compression tes. Do it correctly tho.

State of plugs.

Oil in inlet.

Oil in pipework.

Leakdownt test.

Turbo shaft play.

Does it smoke on full beans?

Does it smoke after engine braking? Like in gear down a hil not touching the pedals then accelerate.

What colour smoke is it?

Quoted from Alex:

Turbo would smoke on idle when warm and would be white smoke, stem seals would be blue smoke on gear change and also on idle when the car is warm. Rings would be a blue smoke under load, but its hard to see unless you are behind the car.

As Phil has said definitely start with a compression and leak test, check the state of the plugs, and check the pipes for oil.

You'll need a compression tester Dave. If you've not done one before then get someone who has to help to make sure you get accurate figures :) You're also best off getting a leak test done at the same time to get a more accurate diagnosis.

What are the plugs looking like?

How u getting on dave? as my car has the same problem & ive found that the more i boot it the more oil it drinks. Went to the the VW fest down santapod a few weeks back & gave my car abit of beans for most of the journey & had to stop for a bit to eat & during down gearing into slip road for service station a big puff of blck smoke came out & when i got back home which was a total distance of no more than 200miles there was bugger all on my dipstick & i topped it upto the max level before i set out. There is no trace of oil in my inlet or tip, i know the last time i chaned my s/plugs they were very sooty black. I hear there is a tool to replace the seals, anyone know where to obtain one?

whats a leak down test? :confused:

My compression resutls 3months ago approx

Code:
Atemps	C1	C2	C3	C4
1	12.5Bar	12.75Bar	12.5Bar	13.Bar
2	12.5Bar	12.60Bar	12.4Bar	12.25Bar

Those compression figures appear OK, as per Phil's guidance from my results:

New Cylinders (145-203 psi) Wear limit (102 psi) Maximum difference between cylinders 44 psi

A cylinder leak test is exactly that; you use a tool to inject compressed air into the cylinder, then crank it manually to see how much air is lost between strokes. It tends to give a more accurate diagnosis than a compression test alone.

What do you mean about high oil pressure?

The trouble with issues like these is there tends to be a lot of possible causes so without narrowing it down it's hard to diagnose anything with certainty. Just because it's smoking doesn't necessarily point to stem seals, it's just one possible cause.

The above tests that Phil pointed out should help eliminate a few things and point you further in the right direction

meaning if the oil pressure i very high all the time...would that ruin turbo seals, stem seals ect?

how much average cost to do stem seals (supply/fit)?

how can i prevtn the car from stalling, as i want to disconnect ic pipe and let it to idle and see if it smoke when i rev it....:think:
