Octavia VRS smoking on overrun

Featured Replies

Greetings,

Developed a slight issue today with the vrs. Nice clouds of blue smoke are being emmited when I lift off after hard acceleration and then coast in gear. It only smokes on the overrun. Runs fine when ticking over and accelerating.

I'm thinking either turbo seals or valve stem seals? What ya reckon?

Looking at your specs (1.5bar) I would say the turbo lol.

I would say valve stem seals. If it was turbo related, it would smoke under power as well.

And I was thinking rings, since it was only smoking on over-run.

Whatever, the cheapest way to sort out which it is from here is to do a compression test.

If the test shows dry normal, it may be the turbo. If it shows low dry, do a wet test, and if the pressures come up significantly I was right!
