: 97 Aurora with Northstar engine..Head gasket problem!

06-03-05, 06:41 PM
hey all I have a 97 oldsmobile aurora and have been diagnoised with headgasket failure. I have a north star 4.0 caddy engine. It all started with it running hot when i am going 70 mph or more or when i am in stop and go traffic. I flushed the radiator and changed the thermostat with no avail... so i just took it in to have it checked.

My brother is a mechanic so he can do all the labor.. I just need to make sure we don't miss anything. I am told we ned some timeserts..where can i get these and what are they for.

The mechanic said he could not see why it happened. I read about bolts backing out. . is that possible? also does the entire engine need to be pulled out? what type headgasket do i need?

and is there some type of how-to on the net for this? thanks

Questions about the Aurora should be in the Oldsmobile forum.
