2002 Cadillac Deville 4.6 needs head gasket.


Asked by May 26, 2013 at 05:10 PM about the 2002 Cadillac DeVille Base

Question type: Maintenance & Repair

Told there are consistent problems with these engines due to the aluminum involved.  Comments?  Also, told that expense of just replacing head gasket is too great considering the chance of it happening again.  IMO car is too old to consider swapping engine, but is in such great shape otherwise it is hard to let go.  Any comments appreciated.  Would love to have the repairs done without sinking $ into something that may or may not work.

These cars are notorious for head gasket failure! You're looking at about $3500.00 to have the job done correctly. The engine has to come out, from the bottom, anyhow so if you plan on keeping the car you might seriously consider just replacing the engine. In addition to replacing the head gaskets there are "buttons" that need to be installed in the head bolt holes in the block. Usually the head bolts pull out of the holes in the block causing them to strip. A friend from work had this done on his '97 Eldorado. A few months later he got rear ended and the insurance company totalled the car. If you really love this car and plan on keeping it a long time, go for it. But make sure the shop knows what they're doing!! HTH. -Jim

Midwest Cadillac Repair comes highly recommended and people bring him their cars from all over. He only charges $2000 if you can get to Palatine, IL.
