2002 Cadillac Deville 4.6 needs head gasket.
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.
