Do you have a PCV valve installed? You may be blowing oil out the breathers. If you're running just a breather in each valve cover, that's probably your problem. The breather is to let fresh air into the engine, the PCV is to keep the pressure down inside the engine.

From under the car you should be able to feel the inside of your harmonic damper to see if there's any oil there. That will tell you if your front seal is leaking.

Valve cover breathers will "Mist" if they're not baffled as well.

Nope.:no: It's not on the vacuum side (one of the runners). It's just to the crankcase. So it would be the same as spraying carb cleaner at your breather on the valve cover.:D It shouldn't change a thing (idle wise).:no:

The corners of the manifold (front and back manifold-to-block at the corners of the heads) are common problem areas. In those 4 spots, silicone is your friend..:yes:regardless if your a firm believer in the cork or rubber end gaskets or not. I always work a bit into those corners just like you pack a wheel bearing to make sure there's NO potential problem.

You'll laugh (here comes the deep south remedies crap again) but once I took some clean cotton balls and duct-taped a good amount to the front corners of the intake (on the front of the block) and made a quick hit up the street and back. Then I pulled it off to see if they were wet or oil soaked or if just the outside of the tape has oil on it, then you know it's coming from somewhere else.

Also, pull your PCV valve out of the valve cover while it's idling and see how much vacuum you're pulling from it or if it's clogged..

I had one of these “where’s Waldo" leaks a while back. I too was getting oil outs the breathers. I still have not put a PCV on :eek: but plan to. Check your dipstick. I had a small leak there. Just my 2 cents on what I went through. Good luck!!

It sounds like your PCV valve is not functioning to me. That's the only way oil can come out of your breather if the valve cover is baffled. It doesn't take much to clog the pintle inside the valve. Go buy a new one and see if the problem goes away. They're cheap. The "shake" test doesn't work if you are using that to determine if the PCV valve is OK.

I change PCV valves as often as I change spark plugs. It's part of a normal tune-up.

Not running a PCV valve will cause your dipstick to pop out of the tube and leak too.
