Why would a 1998 Cadillac Deville smoke really bad when started then stop after 10 minutes with no leaks?
Blue smoke, the valve seals may be leaking; white smoke may be condensation build-up in exhaust pipe; black smoke may be too much gas delivery at start-up.
Do you need a lift kit for 22' rim on Cadillac deville?
It will if you do modifications to it i have 1995 Cadillac deville on 22"defy kasino rims and i had to unhook air lift shocks add spring spacers to all 4 shocks and fold in the front strut plates just to make it work i really don't recommend it at all i regret doing it.get 20"they fit a whole lot better
How do you replace the head gaskets on your Cadillac deville?
you don't Not unless you really know what your doing. You would have to pull your engine out to replace both heads. To have a mechanic do it, it would cost upwards of 1,400 to 3,000 dollars because of the work and how long it takes to pull An engine out and replace the heads and put it back together and into the car again I suggest you start saving up ;)
