Author Topic:   oil out breather caps?

We have a decent amount of oil coming out of the breather caps and I was wondering if there is any way around that. The breathers are installed on the drivers side, and we are running SAE 50 weight oil. The car runs well, but it tends to leak on the manifolds and start fires (yeah, we know from experience). Is there any tricks to this or what should we do? Thanks.

we have taken shop rags and zip tied them around the breathers also you could take some old radiator hose and tubing and put the hose on the valve cover tubes and then mount the breathers on the end of the hose and tie then to the front hoop bars

Yeah, I had definitely thought about relocating them somewhere else. Just couldn't find a good spot for them. Thanks for the tip about the rags. That might work out ok. I would rather not have to use the fire extinguisher this week if at all possible.

The other you could check is if there are baffles in the tubes, and if they have been bent open more for adding oil faster. If they are bent way up or way down try to close up the gap some if not the rag work good or i have used socks on mine so that when you pull em all the way on there is a lot of sock bunched at the bottom to hold alot of oil befor it drips. Oh ya one other thing i did was to push the breather all the way down on the tube, it seemed to help some. Good luck

Hey, I like the sock idea. I wear size 16's, so my socks are plenty big . Thanks for the tip. Also, the baffles aren't bent. I did already check that, and they are pointed the correct direction.

Your idea sounds pretty good Az, but you kinda lost me. where does the foam go? Are you talking about putting the foam inside the breather tube? I would assuming that the fuel cell foam compresses nicely? Unfortunately I don't have any of that tonight. The only thing that I have resembling that is roll bar badding, but I am guessing that wouldn't work very well. Rags maybe? Thanks guys.

The engine has done it from ever since the first race, and it was just rebuilt. I don't think that is the problem. I will try and find some open cell foam though. Anyone else have any ideas?

Hey i like that foam idea will the oil make it get soft or will it be ok? I have been worried about putting somthing in the tubes for fear of peices going down in the head, but that fuel cell foam is pretty tough. The forum is great for stuff like this keep up the good work guys Well off to the races see ya sunday

brillo pads inside your breather works good too. They don't fall apart and still breath well.

If you are huffing oil and it's a fresh motor it's still a ring problem....the rings haven't seated yet.......us guys with all the big bucks don't have these problems because we go through this on the dyno.................ROFLMAO

I too use the socks on the breathers.....
after about 2 or 3 nights the rings have seated and the oil bath stops. but I leave the socks on anyway.......they won't get so full of oil they drip......

We use a rolled up piece of scotch brite (plastic brillo type stuff)in the tubes. Works great, breathes well, no mess, no socks....

My rear breather did leak on the manifolds
and cause a fire.so i cut the rear one off
welded up the hole and welded the breather back on in front of the other one.and i put a shield over that one under the bottom of cover,works great.

Man, this place rocks. I tried the sock idea, and it worked like a charm. Now it is time to move onto bigger problems...
