Pcv location question.

I just have a screen covering my turbo. Is it ok to weld a hose barb on the a2a pipes and connect it there?

No.

That PCV is designed to have a vacuum while you are in boost. You could go with a breather on the valve cover. With a breather you end up with a film on the valve cover that needs to be cleaned occasionally. Ring seal may not be quite as good without a PCV valve.

HTH,

I have a breather for the driver's side. I should have been more clear. The passanger side is the one that is just venting to the atmoshphere right now. Is that ok or can i plumb this line in?

I wasn't too clear either. I was talking about putting a breather on the passenger side, also. Remember the stock PCV setup uses 2 valves. One works in boost (connected to the intake crossover). The other one works in vaccum (connected to the throttle body). Hooking to the A2A would not provide vacuum to the PCV under boost. Did that make sense?

I think the best option would be to put a filter on there. Have you tried a cobra elbow?

You could always go to an electric vacuum pump, or a Moroso fitting on the exhaust.

PCV's & Valve Cover holes

PCV's & Valve Cover holes

I'm getting down to the short strokes on my rebuild, and about to put the PCV's on. Your info on the hookup of the 2 Pass side will certainly help. My stockers are shot after ~ 100K - no surprise. I don't know if they are specials or not - I see a CV799 # on them. Hopefully they R available at the chain AP stores.

My major question is on the drivers side. Amazingly, there's no info on the PCV's in the shop manual. What goes in this drivers side valve cover hole ?

PCV - Drivers side

pop a regular air breather in there.

Ok, I'll see if I can find one. What went in there - Driv side - stock ?

A pcv valve or just a straight fitting(memory struggling here) that had a hose coming off of it that connected to the stock air box.

I believe it was just a hose running to the stock air box.

Both stock PCV's were on the pass. valve cover.

Just went to the AP stores. Pep Boys didn't have the PCV, O'Reillys' didn't have it, but AZ had one they said substituted - the Deutsch PCV227. Seems to fit anyway.

I checked the drivers side VC hole. Ur right, it looks like the air inlet hooks in there. The hole size seems like it might fit another PCV. Not sure if we want 3 PCV's, do we ? It would seem like we need one of the holes where the crankcase could breath freely w/o a valve inhibiting it.

Those breathers w a very small hole (3/4") are hard to find. I always like the kind that has a side outlet where U can run a hose off it down to the bottom of the engine block to get rid of the oil fumes.=
