So, I just bought this car a few weeks ago. The previous owner assured me of no leaks. That being said, when I take the car out for a drive and return, there is oil everywhere. I'll be a bit more specifc, oil on the top of the passenger side valve cover, on the shock tower and on the underside of the hood. All near the front of the car, passenger side near the dipstick. It seemed as though it was leaking from the passenger side valve cover. So I did the logical thing and replaced the gasket. Easy enough, however, took the car out today and same thing. I checked the oil level and it is actually about a half inch above the overfill line. My question is, is it possible for oil to spew out of the dipstick if the oil level is too high? If that's not not it, then WTF?
I wanted to also mention that when I changed the valve cover, I used a cork gasket, put RVT down on the valve cover before putting the gasket and then again in between the gasket and the block...was that bad?
Sounds like you've overfilled the engine. Also check to see that your PCV valve is working correctly so your crankcase is not building pressure. No need to RTV valve cover gaskets. Next time buy the Felpro neopreme gaskets. They last forever and never leak. And they're reusable. Install them dry (no RTV or gasket glue).

You may have too much oil pressure in the motor now because it is way over full and it has to go someplace. Too much oil pressure and you may blow more gaskets out. I would drain it out and put in the correct 5 qts.

There is only about 1K miles on the engine since it was rebuilt. I have not changed the oil yet since I got it. So the previous owner must have fillied it to much. Would it be worth take the doing the gasket job again? Will the RVT plus the cork gasket be ok? Was it just overkill or will it cause leaks?
However....You mention changing a Valve Cover gasket? Did your car have this problem before, or did you just make some recent changes, and then the symptom appeared?
I changed the valve cover gasket because it was leaking previously from what I thought was the valve cover gasket. I was just out in the garage and drained at least a quart of oil out of the car to make it read correct on the dipstick. I will give it a drive tomorrow and see if the overfilled crankcase had anything to do with it.
Also I want to add, that when I have the car at idle I can't see any oil leaking out. It seems to happen only when driving.
Does the valve cover on the passenger side have a breather also in it along with the pcv valve? BTW is the engine missing or anything like that? I would think you could simply open the hood while the engine is running and rev it up to about 2K and hold for a min or so. With that much oil coming out it should be easy to find the source.
