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.

Coolant is low and leaking out the tailpipe (White smoke ) Oil is OK. Repair is being contemplated. This is the forth time in the last ten years!

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.

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.

Just put a crate motor in it and I'm loosing antifreeze out the tail pipe. I have figure it's the intake gasket. What's the proper way to seal it off for no leaks alright tried redoing the gasket once but I have the same problem again? No water in oil or oil in the water
