Hello,

I recently put a P1SC in my 99 T/A running @ ~ 7-8 lbs. I really did not have a good PCV/catch can setup in use when I first ran it. I think I may have pushed the rear main seal a bit. If so, I will fix it.
In the mean time, I want to get the proper ventilation set up prior to running again.

At this point, all I have done is the vent on the pass side valve cover is routed to the inlet hat port and I have a breather (in pic) in the oil fill hole.

What is recommended to avoid further problems with excessive crankcase pressure?

By the way I have an LS1 valley cover.

Thanks

Your combination with using the Caspers valve cover breather should be all you for no more boost than you are producing. Bob

Thanks Bob. One last question. I have read that it is not a great idea to run a hose from my pass side valve cover to the inlet hat because of the oil being pulled into the head unit. It makes sense but, how big of a concern is it and is there a better way?
Thank you
Bob

Thanks! That is, by far, the most helpful info on PCV/catch can setup I have seen.
