The inlaws own a '99 deville .
Engine started overheating during a trip. They needed to top off coolant
every couple days (1/2 - 1 gallon).
Cadillac dealer says coolant leaking into #1 cylinder and that is causing
the problem (head gasket/crack/etc).
Cadillac dealer says, "put a new engine in it" (~ $6500 total). Cadillac is
not interested or willing to repair the current engine, they just want to
put another engine in.
I was thinking i could just do a top end recondition/rebuild and replace the
head gaskets etc as a favor to save them the $6500 as they would just pay
for the new parts.
What i think i know after some research on the web
(and could someone please share info or confirm) ...
1. Seems this cadillac engine style has a history of this head gasket
2. Replacing the head gasket on this car is a **
> It is a tight squeeze under the hood

head threads on

> lotsa bits to pull to get to the head.
3. Almost easier or better to drop the engine and trans together to do the
head rebuild ?
therefore why not just put in a used rebuilt engine and save the time
and labor effort.
Did i miss anything ?
Any recommendations on which path to take ?
Any recommendations for a new/used/rebuilt engine ?
Is there a compatible NON-Aluminum engine that would work in this car ?
Thanks for any helpful advice,
