[s-cars] Another Boost Leak - Searching for the PCV Valve - xpost

Thu Aug 3 08:14:30 EDT 2006

Bob-

You are correct about the difference between the N-80 valve and the other $20 check valve.  I installed all but the more expensive N-80 last night in the dark, bit of a pain in the arse.  The larger circular valve at the rear of the block was easier to get to, but in general that hardest part was ac cess.

I found a huge tear on the underside of the "T" hose after removal.

Thanks again.
