I believe the source of the
oil leak is at the top front of the engine. Everything down and back from there is covered with
oil (I'm a procrastinator and let the leak go too long). There was a pool of
oil in a water pump cavity on the passenger's side. The distributor is more on the driver's side. Oil is on both sides of the front of the engine, just seems more on the passenger's side. I've torqued the intake manifold (it was amazingly loose!) and replaced the distributor o-ring. Seems like given the location of oil, it would have to be either the intake manifold or the distributor. Does the oil pressure gauge line attach just behind the mechanical fuel pump or is that the tach? Sorry to be so ignorant about this and appreciate any guidance. What a mess to clean up!
