Mysterious oil leak revisited Options

[Ctrout]

A few days ago, there was a post about a mysterious oil leak. The question was asked if the motor needed to come out to repair a leaky oil pressure sender or oil cooler. I have the same question as I have a pretty unhealthy leak coming from directly above the oil filter. Something above the filter leaks onto the filter, runs down it, and drips from the bottom, forming a puddle directly beneath it. I haven't tried to nail down the source yet so I could get lucky and find that it's just the filter. If it's the cooler or sender though, I'd like to have an idea of the work involved. 1974 1.8 L-jet.

pulling the sender is pretty easy. clean the area where it screws in, put the sender back in, leave the rubber boot out and start it to see if it's leaking. my 75' did the same thing, bad cooler seals. is the top of the filter one big puddle? there is a tech article at the bird re changing the seals with the engine in, i opted for the engine removal. you pretty much have to tear the front of the engine apart.
