Maintenance, Engine & Driveline TechThis forum is brought to you by The Speed Syndicate (TSS) in Burnaby. Discussion of maintaining your engine, transmission, differentails, rear ends, and mods associated with "driveline" parts..
So my mk4 TDI is starting to periodically blow blue. However, the only time it does is when you're really winding it out and manage to peg the limiter. My initial thoughts are the valve stem seals but that's just a guess. Any suggestions?
Also, doesn't blow on start up or any other time. And if it sits for a few minutes afterward, it stops spewing smoke.
