I had a lot of oil leaks due to the clogged crankcase ventilation filter mounted on the block behind the driver side valve cover. It is press fit in the engine, and since there is little room where it is sandwiched between the valve cover and firewall, I could never get it out. I used someones advice and simply kept flushing it with engine cleaner until the brash mesh in there was looking very clean. Then I obviously had to change the oil. With the brass mesh clean and new filter installed in the canister, I replaced the PCV valves under the valve covers, valve cover gaskets, valley pan gasket and added a gasket to the distributor that was missing. I have not leaked a drop since.
I would have never even known there was brass mesh in there if Barry had not enlightened me.
