January 7, 201511 yr 1990 Loyale in sig I have a horrible oil leak coming from somewhere on the front of my engine. I can't remember if I replaced the front main seal or not, but I did replace the seals for the cams (although one is leaking a little) and I never did the oil pump seal. From what I can see, it looks like it would be coming from the front main seal or the oil pump, but I really can't tell. Which is more likely? I guess if I do one, I could do both...but I think I can do the oil pump seal without pulling the radiator...it's been awhile. Any advise would be nice.
January 7, 201511 yr How long ago were the seals last done. I am betting it is the Oil Pump Seal if it has never been done.
January 7, 201511 yr If you do one do both. I was able to do all without pulling the radiator on mine.
January 8, 201511 yr no stop leak! fix the oil pump shaft seal. Maybe the steering pump reservoir is leaking.
January 8, 201511 yr how the heck do you do the front main seal without pulling the radiator? A small hammer and tappity , tappity until it's in.
January 10, 201511 yr Author no stop leak! fix the oil pump shaft seal. Maybe the steering pump reservoir is leaking. I'm aware of the stop leak... I have used the lucas oil additive...looks like gear oil...with success before. And yes the steering res is leaking, but it has ATF in it and the oil I'm seeing is fresh motor oil for sure. Also replace the PCV valve too. Your new seals will thank you. Will do. good call. I also have a PCV hose retro to put on that I pulled from a car in the yard.
