PCV Delete, Catch Cans, and Unmetered Air

Girald

Update from my last post...

The PCV and CCV definitely breathe together.. Originally i posted that adding the PCV to the catch can would be the answer, with vented CCV...

not the case... so the exit pressure from the engine want to find a way out... if there is restriction ( catch can filter element etc) in the PCV, the engine will puke out of the CCV... i found this out after doing some workj to the car and found what looked like residue under the car resembling an oil leak... after searching for leaks, i tracked to the wheel wells where my CCV hoses were.

So naturally, I would suggest a 3 port catch can per bank (2) OR a tee-off at the PCV flow through point per side, where you can bond the 5/8 line with the 3/8 line and send all outbound to the catch cans... the 5/8 line is odd since the exit from the CCV exit ( look inside the plumbing) is much smaller, so i dont anticipate a pressure bottleneck.
