So I have Ford racing valve covers and the breathes that come with them are pretty much worthless since they flow very little air and don't seal well at all. Im sick of oil getting on my headers. I'm think ill weld a Bing on each cover where the breather holes are but need some advice. I like the shotgun evacuation kit but dont think the breather will fit under my intake so I think ill just run lines to a tank. Their tank is nice because its baffled to help eliminate the filter getting oil soaked unlike most on the market. Only problem is the tank only has -8 an fittings on it. It'd be nice to go with -10 or even -12. Not sure -8 isn't fine though. What do u think?

As for my PCV I'm thinking ill leave it in tact with my check valve but I've thought about eliminating it. Thoughts? I've been looking on turbomustangs and might do an exhaust evacuation ir vacuum pump eventually but the first step is to at least get my filters to not leak.

I just called shogun and bought their breather tank. Now I just have to decide if I wanna weld two bungs on the front of my valve covers or get new ones that don't already have filter holes in them. Id like to keep the baffles though but not seeing a way of having bungs up front with baffles since a set of valve covers is typically the same valve cover with quantity two, meaning one of the holes is at the back when u install them.

Well I guess no one had and advice but u think I'm just going to buy black trickflow covers and weld a bung in each of the near the front and run each line into the can. Hopefully I can make the covers look good after removing the powdercoating and welding in them. Also I hope not having baffles anymore isn't going to be a nuisance

You can buy bolt-in bungs so you dont have to weld them also.

I have Trickflow breathers with bolt-in baffles on the inside of the valve cover and I havent had any oil issues. If you get any good amount of blowby though, you will almost have to go the catch can route.

I've got the Summit brand '347 die-cast' covers, and they have bolt-in baffles on the inside of the covers. I have the pictured chrome trickflow breathers that simply push in the pre-drilled holes in the valve covers with the supplied rubber grommets.

Again, I have a fresh rebuild with almost zero blow-by, so your results may be different if you are running boost on a stock original rotating assembly that creates blowby....

Ah yes too bad theyre tall I bet those filter holes seal off oil better.

I just received my black trickflow covers just have to figure out the cleanest way of welding the bung on without screwing the powdercoating too bad

What the Hell I guess trickflow valve covers don't fit with stock rockers. Thinking bout just using my Ford covers now and one if the bungs will just have to he in the back of the valve cover even though it'd be better to have both in the front although I guess ill have baffles now

They are not hitting vertically. Horizontally there is a problem. The cover is essentially touching the outside rockers on the sides. I guess stock rockers do look wider than roller rockers.
