Adding oil vent tubes to the valve covers...none on the motor. Got the CB kit. There is an O Rings inside the valve covers, and the nut on the outside. If I hand tighten the nut, the O Ring is squuuisssshhhhed out and doesn't look good.

Suggestions? Gasket mterial? Superglue? Thanks Bill

McMaster has Viton washers.

Or PACK it full of RTV! (calling Cap'n)

Miracle putty.
Its way better than jbweld.

So you're doing this to non-vented heads, right. 2 ways: (A) Vent the heads like they were intended to be. (B ) Weld in those POS tubes.

The Cap'n

Not really sure, but I've been told that the valve covers (rocker box covers) run about 1/2 full of oil at times .... could be a lie, but the positions of those vents look like they suck a bit of oil. Just a guess.

The stock location is way above that level.

JB Weld forever .......

Unless he installs those covers with the port at the top. I was thinking the same way, Ron.

Yep they'll vent at the top of the cover back into the breather box way up on top hung on the firewall. Can't afford to put the vents into the heads right now. Thought about something like miracle putty but didn't know what oil and heat would do to the joint. Can't get any higher on the cover or it'll be in the curve. Picture doesn't show it very well but they're actually pointing slightly up when on the car.

If thats the kit with the EMPI breather box, replace the hose that came in the kit with something else. The hose in my kit was not reinforced at all, and started breaking up within a single year.

I replaced it with truck fuel hose from NAPA, which has a fiber reinforcing layer in the rubber.

Yep. It'd the empi kit. What did u do about the O rings on the nipples? I'll pick up some oil hose. The kit hose looks like it came from slip n slide
