2003 DeVille DHS, 127K miles.
Went to do an oil change today and I knew I had an oil leak on the oil pan, but because you have to drop the transmission in the Caddy, your truck, and your lawnmower just to access it, I'm not going to bother for now, it's only an annoying drip.
However, there seems to be oil also dripping ONTO the oil pressure switch. I can see some oil creep on the sides of spots over the top of it. If I shine a flashlight up behind it, where I can see the exhaust manifold, there is some oil creep around the manifold on the passenger's side, and oil creep all over what appears to be the AC compressor.
I do suspect the oil filter adapter gasket is leaking as well, since it has a lot more oil creep on it than anything else, but I'm not sure where the oil would be coming from that's getting on the passenger's side exhaust manifold. I'm not even sure how bad this is because there's so much oil creep under the car.
I've wiped everything down and will put it back up on the stands later this evening after putting 50+ miles on it for an afternoon trip down to the beach.
Any suggestions on what might be leaking?
Also, any suggestions on getting the oil filter adapter off to replace the gasket? Looks like only you skinny folk are going to be able to find all the bolts that hold it on there.
