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.
