I got some blow by oil at the rear seal with my A&A Corvette S/C setup. I have a catch can between the valve covers and the S/C air cleaner.
If I put on a breather at the oil fill cap will that ease pressure and not allow the rear seal blow by?
Is there an electric pump that I could use with a vacuum switch to pull pressure from the crankcase with boost mode to prevent the problem? I have an 8 rib setup and don't see any easy way to get a mechanical pump in there, the reason for wanting an electrical pump.

Pretty late in this thread but very interested in this! I went back and forth on pcv to breather setup for along time. What tipped my decision in the end was seening the new copo whipped camaro and it was just running breathers in each valve cover and nothing else so that's where's I'm at.

Ive really only read the last 2 or 3 pages of this thread. I have seen oil blow by out of the rear seal using the RX dual valve can. I talked to Matt at RX Performance and he hooked me up with the Monster can. After I install it I will put an inline filter in between the valley cover nipple and map sensor to my boost gauge and use the gauge to measure crankcase pressure/vacuum while cruising and in boost. I am pretty sure that nipple is capped anyway after the install so it should be a good test. Anyone see a problem with doing that?

Ok so let me get this straight as I am a little thick headed
I have a sts twin turbo setup one of the first gen only one wastegate and only one
Scavenge pump it’s all good
I want to install a catch can and from what I have read in this thread
It seems to me that if I were to install a dual valve can I could get rid of the pcv switch
Am I correct in that ???

They did field my calls to a certain extent.
But once I finally got the Monster2 C/C I was happy, just wish they were a stocking item, from what I understand they are made to order.
Thanks,Matt
