Blowing oil out of my breather cap
Hi all,
I'm losing oil out of my breather cap (I have one of those stand-a-lone push in chrome breathers).
My valve cover is just covered in oil to the point that it's running over the back of the engine and transmission. If I clean off the valve cover and go for a drive, it'll be covered in oil again. Nothing comes out while it's just idling in the drive way, so it's not just a regular leak.
I replaced the gasket and breather, thinking it was a bad gasket, but after putting on a fresh gasket and breather, I drove to the corner and back and it was enough to already cover the valve cover again.
My PCV valve works, I don't have oil coming out of my dipstick tube, etc. Not sure what else to do. My engine's a mess and I keep having to top the oil off.
Thanks for any advice.

It's been a year or two since I've had the valve cover off, but I didn't inspect the baffles. It's the original cover though.
The PCV is connected to a large rubber vacuum hose that goes directly to the manifold itself. However, I guess I haven't checked to see if the port itself is clean. I know it is working because pinching the hose causes the PCV to *click*, but that doesn't mean it's not a weak vacuum signal. I'll check that.
Other ideas are welcome.

No, this has been doing this for a while. I just figured it was due to a bad breather/grommet and hadn't gotten around to replacing it yet. However, I replaced the grommet and breather before my recent trip and noticed that oil was still blowing out, so figured it was time to ask the experts.
