Question about 1989 Cadillac Sedan DeVille

1 Answer

1989 Cadillac Deville has started with oil leak. Not that significant - learned a mechanic had over-filled the oil, but another says not the problem. Have 72,000 original miles. Also having trouble locating a mechanic in the area to work on the car due to its age. Any advice or help?

Got an older car? Find an older mechanic...Someone who remembers there is an engine under the hood, not just electronics.
Typically you have nearly a one quart "leeway" on overfill. Depending upon where the leak is, you could try using an engine sealer/conditioner like the one made by Lucas...I've used it and it's pretty good. Remember though...It took a long time to develop a leak, it will take some time to soften the leaking seal and slow or stop the leak. And...there isn't a chemical in the world that will replace a failed part.

I have an 88 Cadillac Deville. 2 months ago I had a new fuel pump put in. It's making a whining noise and the car keeps dying and sputtering. What else could be the problem to make the pump go out?

My 1997 cadillac deville, northstar w/85, regular oil changes, burns almost 2 quarts of oil every change. It is not leaking.


If your car is losing oil, and if there is no evidence of oil leaking, there is no question that it is either losing it through piston rings or through the head (head gasket or valve guides).
Best thing to do is use a HEAVIER WEIGHT oil than specified for the vehicle when new, regularly monitor your oil level and be sure it never falls below one quart low, and consider having the engine overhauled when you start noticing a performance deficit or hear mechanical noise (such as rod knock) from the engine.

Leaking at the oil filter


Check to see if there are two gaskets. if the rubber gasket from the old filter is stuck on from the change then you have 2 gaskets on top of each other. being rubber when oil starts flowing they won't maintain rigidity because the one stuck on from before won't have the metal lip of the filter holding it

Hmmmmmmmmmmmmmm. I guess you find and push the "fix oil leak" button or take it to a mechanic so he can put it up on a rack, find the leak, and give you a price to fix it.

How do I change the oil gasket??


Are you talking about the oil pan gasket, valve train cover gasket? Id so on either one you must remove the old gasket an replace it. You can try tightening the bolts some to see if that stops the leak, but if not, the gasket should be replaced.
