Oil leaks from the valve cover gaskets, timing cover gasket, distributor o-ring, and rear main seal area are common. The leak at the rear main seal area is generally not the seal itself but the bearing cap to the engine block seal. An oil leak could also be internal to the distributor, if oil is found inside the distributor then the distributor should be replaced.

changed the rear main seal and pan gaskets and it didnt even slow the leak down in 15 miles it pours out 3 quarts ollks like the pasenger side of the engine rear above the oil filter area and more to the middle of the block im thinking putting out that much oil its gotta be on the main oil passage from the pump is it possable it is a leaking plate under the oil filter and can that be replaced by me and or the o ring on the distributor? and or the sending unit on the block by the distributor i cant see the valve cover leaking that much but i have the gaskets for that now and will do them too runs perfect and has 186000 miles doesent burn any oil just leaks like a sive i had the same problem on my last ramcharger and the main seal fixed the problem this is a diffrent issue obviously
