Oil coming out valve covers...

[Unofficial]

Lately I've been loosing a lot of oil out of my valve covers. I got new gaskets because they were leaking. No more leaks from where the gasket is, but I'm blowing a lot of oil out of the grommets, they fit fine but there's still oil all over the outside of the valve covers wherever there is a grommet. My oil breather is soaked with oil, even with a baffle underneath the grommet. The PCV valve is brand new, any ideas? It's a 350 tbi with a mild cam by the way.

blow by?

     x2 on the blow by.  Better take a look at your oil pressure...

Well my oil gauge is messed up...It jumps around all over the place. When it's steady it's usually between 15-30psi. Sometimes when I come to a stop though the gauge will read at around zero, but I figured the gauge is just out of whack.

Can anyone go into more detail about the blow by? Is that when I have too much pressure in the crankcase? (Bad rings?)

This motor was completely rebuilt about 10k miles ago...

Does your air filter have oil on it too?

No oil whatsoever in the air filter

I know you said your PCV valve is new; but re-check it anyway, check it in place with the engine running. Pull the PCV valve from its grommet and place your thumb over the PCV valve opening. You should feel it click. If the click sounds or feels mushy, replace it again.
Also check the line from the valve to be sure it isn't blocked or kinked.
Another way to test it is to remove it and shake the valve. If it's good, you’ll hear a solid clicking sound.

im in the same boat but mine used to be only when I hit high rpms but now its all the time went to change gaskets pan and covers then I saw oil on the dip stick tube so now my truck is parked to I rebuild a 350 or build a 383

Make sure the drain holes in the heads are not blocked a guy from work had that issue with his truck.

The PCV valve is literally brand new. I shook it and there's a good click. And I just really doubt that I need an overhaul... Like I said, this engine was completely rebuilt about 10k miles ago! I guess I can check the drain holes like screamin86 said. I just find it odd that I'm getting oil dripping from the breather filter even when I have a baffle in the valve cover underneath it.

Did you really over fill your crank case?

If I did overfill it, it wasn't by much at all. I guess I don't know how much it would take to leak out though.

On a long shot, maybe your exhaust is plugged up and causing the exhaust to be pushed out past the rings. That would take a lot of blow by to get that kind of oil leak.

I recently chopped off a big part of my exhaust... It was mandrel bent at a 90 degree angle coming out before the rear tires. But I didn't like the look after a while and I cut off the exhaust maybe a foot after the mufflers, could be more I don't remember exactly.

What kind of valve covers and breather do you have? If it's blow by you'll have a lot of smoke in the crankcase with it running.
