Valve cover baffles
 

I have been thru the vc baffle threads a few times and had done what I thought was one of the best VTA setups. Had a -10 fitting welded on the hotside, I enlarged the center to hotside hole as well as added a second hole next to it, and then added copper scrubbers. I didn't add a hole on the center to colds side baffle as I'm going to leave the pcv hole plugged initially and see if the hotside only will be sufficient. I then sealed it up with RTV and but blue Loctite on the screws for the baffle plates.

I posted a pic in the mt.net facebook group and from the response there it was a bit mixed so I wanted to post here in case the OG's weren't some of the ones replying on FaceBook. Some had suggested no scrubbing material at all, someone else suggested moving the scrubbers further away from the exits so that oil doesn't wick into the exits off of the scrubbers. It would suck to have to pull all the rtv back off but i'd rather do it now while it's still out.

Thoughts? Thank you

I don’t have a lot of experience with this and I’m certainly not an OG however…

A few recommendations I have is keep the scrubbers away from the port holes/valve cover exit. I’m also going to be running a VTA setup but I’m only NA. I drilled the one hole to 3/8 and called it good. My thought process was if you drilled a hole from the center baffle to the cold side the hole would be aimed right at the exit of the VC on that side and would essentially bypass all the baffling. The opening on that side is probably big enough already. I could be wrong though.

I think your fine, as is.
If you have serious blow by, the scrubber is not going to make a bit difference. And if not, you won't collect enough to drip through in a significant way anyhow. Learned that from experience.

Personally I think the scrubbers are overkill, and potentially looks like a problem down the road.

I was getting issues with positive crank pressure, but i alleviated the issue by running a gtx valve with a one way check valve. Tapped the breather, 3/8 npt to AN10 to a breather box/catch can. I also enlarged the breather holes/ports inside of the valve cover just as you have.

Seemed to fix my positive crank pressure issues. Was running roughly 17-18lb making 300whp, no longer leaking oil through my seals :likecat:

That's a very good observation on the pcv side port I didn't even think about, I'm glad I didn't drill that hole. MY thought process was the same though as far as the inlet on theat baffle i pretty large and should work fine as is if I end up needing that side to vent as well.

Seems the scrubber idea may not be the best idea then, I think I'm going to reopen and just pull the scrubbers out. The only one I could see leaving would be the center baffle and even then, it may not be worth it so I'll just pull them all out and reseal them. Thanks for the input.

I do not think they will do you any harm. I think it is not worth the effort to take it apart, and clean it up for the reseal.

Are those scrubbers copper (plated)? I'd worry about corrosion if they are. I used stainless - just in case.

So did I.
