valve stem oil seals

[stevegti6]

ive noticed that after ticking over for least say 10 mins or so i get a little puff of blue smoke when i rev it
and when i start from cold its a very small amount of grey smoke it puffs out then it clears with in a second its not using any oil and it does not smoke on full boost or on the overun
could this be valve stem oil seals
will this get worse

 

[h17och]

mine are gone (could only tell coz i looked into the head with a torch! never noticed smoke tho! but yea it sounds like your is stem seals!

im leaving mine till engnine comes out again in winter

Mine are being being sorted now.

Valve stem oil seals normally smokes on overun when you put your foot down again.

Yours could be the turbo seals or rings tho.

Do a compression test to see what you get. I got 180's across the board but i think more than just the seals were causing my oil burning.

 

[stevegti6]

its only done it the once the oil level is just over the max im kepping a close eye on things
i might of over filled it oopps

 

[h17och]

that could be the probs mate! over fill can be worse than under fill

Mines only smokes when it idles for 20seconds + and pull off or reved it gives blue smoke. i havent seen it do it onoverrun. can i rule out the stem seals? or it still could be possibilty

Hi mate that sounds exactly like i have,there a certain hills i go down and i can guarantee once i'm at bottom and put foot down again i will get a puff of blue smoke.

What were your symptoms?

Any idea of cost for these mate? can they be done easily enough by yourself?
cheers

btw how did you do compression test?

 

[Big_daddy]

Mines smokes on idle, in traffic when pull off...let it roll in a gear and putt foot down...BIG puff of smoke...
Stem seals a head off job..(some people say can do it with head on)....most garages charge between 400-650ish...

My compression results

Atemps	C1	C2	C3	C4

[Cowie]

what did you use for compression test mate?
vag-com? and how ?
cheers

 

[Big_daddy]

compresion tester (availble from local auto store/halfrauds) or any garage can do a compression test for you...

 

[Cowie]

cheers mate

After fitting a catch can to clean up the PCV ventilation/recirculation stuff mine got a bit better. Changing turbo it got better still, and I think the last 10% is probably valves but I've done 183k so it's probably not that bad!

Old thread but hoping for some advice.i have a seat leon cupra engine code AUQ.
For some time i was getting a cloud of blue smoke on cold start which clears straight away. This would be after the car had been left standing for at least 10 hours.
Also once the engine is warm occasionaly i wil get a puff of blue smoke when pulling off from traffic lights.
And when reversing when the engine has warmed up i somtimes see a puff of blue smoke go past the pasenger side window sometimes worse than others.
The symptoms dont happen every day and seem to be worse in warm weather.

I had a compresion test caried out around 5 months ago and all was well
also boost tests no leaks

i changed the oil on the car which seemed to improve the symptoms for around 2.5k but now the symptoms are coming back again not sure what to do next? ??
