I have all the vents going to the catch can with the pcv before it, than line from catch can into intake, with check valve.


The catch can looks very close to the header but its about 3" from it

You should put the PCV valve directly attached to the intake manifold. The way you have it now, you will be boosting the catch can...

Also, you will not have any ventilation under boost either (when you need it most). Take that T out of the line, and run a hose coming from the front port on the p/s valve cover to the intake side of your turbo. Then you should be good.

You can buy new vacuum line for like $1 a foot... Thats the only way to be venting the crankcase while in boost unless you vent to the atmosphere, then that totally defeats the whole PCV system...

Yea I was thinking about putting a breather on one end of the catchcan so it could vent to atmosphere

but then you are deleting the PCV system all together... May as well just plug the holes on the intake manifold and put breathers on the valvecovers...

what if i use check valves in place so when under boost I can vent to atmosphere and while not in boost it will act normal

That would be a very complex system... Way more complex than just running 6 or 8 feet of vacuum hose. And more costly too. KISS method works great.
