Buff of blue smoke on deceleration After Stage 2 Remap..Please Help

(1/3) > >>

Mego:
Hi Guys,

i have an 2007 golf gti mkv with 107k km, after going stage 2 tuning i can see a puff of blue smoke when I'm cruising a downhill with my leg off gas and after a stop and start to move again i can see a puff of blue smoke from my exhaust..this happen on 1st gear or 2nd gear(if not fully stop).
i have changed my pcv and problem still exist..a friend told me to check the valve cover and i did but couldn't make sure its cracked but i can see some oil in my rear breather tube(rear pcv) which has no valve inside it(old version).

any help would be much appreciated.

Try an R Tech PCV Delete mate. usually works. mine does the same.

Mego:
Thx bro,,i will try it and see

Oil inside rear breather is fairly normal. I doubt an R-Tech PCV delete will help in this instance. You'll probably find its either from the turbo or valve stem seals. Did it start shortly after removing the catalytic converter for your stage 2 map? If so then it could well be coming from the turbo

yes bro exactly..i was on stage 1 +revo intake for more than 1 year and car was fine..no smoke at all and no smell if burned oil at all..after going stage 2 with dp the problem started and i can see a buff ib blueish smoke when going downhill and when start to accelerate after downhill finish,smell of burned oil most the time..

i have 2 options now..change valve cover or change turbo..u sure its turbo related bro?

Thanks
