I seem to have a problem with oil pooling on the top of the engine tin, where the red circle is. Just changed the valve cover, and its dry, so I know somehow its not coming from there. I wonder if its coming from the little hose just to the upper left? BUt thats dry too. At a loss here...

If the leak started recently after changing the VC gaskets, I'd agree that's where you need to focus.
Crank case pressure is probably pushing the oil out of the top of the gasket. |

The leak was happening before I changed the VC gaskets, which were leaking bad, but now the vlave cover is completely dry, so I dont think its that. I tend to think its the head vent hose, but that seems to be dry too. One clue is that it only leak during "spirited" driving, not when the car is idling.
Finally the head vent hose is connected to a silver box on the firewall pictured below. (not my engine, I dont have carbs, but I do have the box) Box is also not leaking. Thanks all, Eric Attached image(s)

Ok, so now I am confused as the 1st pic was from a D-jet car and your 2nd pic had carbs?
pressure on a properly setup d-jet car should be venting though the head vent provided it has not been fuch'ed with. I could see on a carbed car how the pressure could blow out the valve cover gasket if it was improperly installed and the normal vents have been jacked around to where they are not evacuated properly. Makes it somewhat harder to diagnose when you describe a problem and then show a picture of a completely different car. Also, if the carbed car is yours, it looks like you a have the head vents and the PCV venting to the same source. If you still have the PCV in place which it looks like you do you may want to remove that as it was intended to be connected to manifold vacuum. |
