I replaced the gasket at the turbo to cat junction. In doing so I broke a couple stud's . anyway put it all back together and it runs but no boost. Due to the weather I took it into a shop.and they did a leak test and no boost leaks. They are telling me all the boost is going into the crankcase and it could be a bad piston ring or a bad valve (something major $1500 at.least). Does this sound right. I drove the car 170 miles and it ran fine I went 80 no problem just 0/boost. I noticed the old pcv system on the block was cracked and replaced it with one from 034 motorsports. Can anyone point me in the right direction . BTW it has a new diverter valve and n75j valve. Also no smoke from tailpipe.
