PCV Detailed Explanation w/CV and CC info

[Orlandoech]

OMG! Awesome info... I was looking for some info about CVs and CCs and this was perfect!

Well there it is and if you don't have one by now you will need one when you hit the track.

I was told that when putting a breather on the drivers side sends out a CEL on stock PCM's. Is this true, do you need a S1 or higher to avoid. Otherwise I will be doing the breather on the driver side, and the check valve and CC on the TB side

Thanks

I was told that if you don't read the entire thread and aren't able to understand that you shouldn't use a breather, that you should be banned from the site permanently.

After that, you should refill your turn signal fluid.

Seriously, no breather, use check valve and catch cans(plural, meaning 2) where needed.

im running a catch can off the pcv valve to my intake mani. im buying a checkvalve today but i wanted to know does the check valve get installed between the pcv and the catch can or between th catch can and the intake manifold

I believe between the PCV and the CC is where I put mine, but it's been too many beers since then. Read around here, Darrell...breather or no breather? settle this for us once and for all=), for more detailed info.

Put the check valve between the intake manifold and the catch can, otherwise you will pressurize the catch can when you're boosting. You want to contain the boost at the manifold, makes sense, right? The best way to stop blow-by is to install a windage tray/crank scraper assembly. This keeps the oil coming off the crankshaft down in the oil pan and no longer getting whipped into an aerated froth that is sucked out of the valve cover when the PCV valve opens under engine vacuum (closed throttle). I have the Ishihara- Johnson version with the balance shaft assy removed. I now get no oil in my catch can and no oil in the cold side pressure pipe. Darrel Cox Racing makes this as well and I'm sure it works great too. The check valve is a must as the PCV valve will not hold 19 psi boost (like I run) and you will have a boost leak and will pressurize the engine. Highly recommended by Dr Mike
