Chevrolet Tahoe Problem Report
Chevrolet Tahoe Intake Manifold Gasket May Leak Coolant or Engine Oil
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
our leak wasnt oil or coolant but air. The intake gasket was leaking to the outside when the truck was cold thus messing with its idle in cold say sub 45 degree weather. as soon as the motor warmed up and everything expanded it would seal and no leak=good driving. since we paid to have it replaced, no problems with it since. - Visitor
Coolant is low and leaking out the tailpipe (White smoke ) Oil is OK. Repair is being contemplated.

leaking exhaust manifold gasket. Motor sounds like a diesel with a sound like value chatter until it warms up at which time sound goes away. - Visitor

I have coolant leaking into my oil(engine), so it's head gasket or i was told its an air intake valve that goes through the throttle-body or a crack in the block...Drained oil, coolant and replaced...
I have a 95 Chevy Tahoe with a 5.7L V8. I have been noticing that it is leaking oil and coolant...
I have gotten several quotes from dealers in the Denver area, and they all see high. How long should it take to repair these items and what is a reasonable labor rate.
Engine misfires esp when it's cold. This is daily. I've had it checked at the dealership stated...
My Tahoe will not start,when I try there,s a spark coming from the top of the intake manifold....
