i just finished my custom turbo kit and have blow-by coming out of the oil dipstick tube and was just wondering if this was normal. I have a 99 gt with a t-70 master power turbo.

thanks,
Jordan

You probably need a different pcv valve. Try one off of a supercoupe.

I'd post that question over at turbomustangs.com, where they are way more knowledgeable about what's normal or not than most of us are.

Boost is boost. If there's enough to blow the dip stick out there might be ring, ringland, or piston problems. What kind of tune or you using?

yep, who did the tune? Sounds like too much boost or your rings are shot.

Could be that OR it could be that the check valve in the PCV is bad or too weak for the boost he is running and allowing the boost to seep into the crankcase. Since the PCV valve is only a few bucks I'd check that first.
