My '99 GLE just clicked past 100k and I've developed an oil leak. Disturbing - anyone know where it might be coming from?

It seems to be dripping right off the oil pan plug, but that is screwed in tightly so I seriously doubt it is that. Also, this developed in between oil changes - not right after one.

thx!

Probably the oil pressure sending unit. Go buy a replacement from Autozone (etc.) and the socket and swap it out - 10 bucks or so.

Was thinking it might be this - still hope so. Does this require changing the oil to swap out or no?

Just drain the oil, and reuse it - since you'll be right there near the oil pan drain bolt.

I have the same leak I changed the cam sensor (70 bucks auto zone) and the oil sending unit (10 bucks auto zone) and still have the leak about a half quart a month I was told it was the front seal of the crank which should have been replaced when I replaced the water pump 20,000 miles ago.

If the leak isn't bad, then just wait til the next oil change and then replace that oil pressure sending unit. That's what I did when this was happening. And then several months later, the rear valve cover gasket developed a leak as well. Replaced that and I was fine for a while. Then recently, I had another mild leak coming from the rear valve cover breather, the heater hose that was connected to it had cracked due to age. Replaced that so I'm ok for now. So basically, due to the age of our cars, expect things like this to start happening.

Power wash your engine and make shure its all nice and clean....after that do a inspection on your engine everytime you drive your car so you can actually see where that is coming from.
