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.

My intake gasket was leaking also. I simply put Bars Leak in and it completely stopped. Amazing. I also want to add, that i have owned many trucks, newer ones, and I would not trade this good old truck for any of them. This is one tough solid truck

I bought the truck used and it was leaking oil at the time. The leak slowly (over 10 years) became worse. To date, I have not fixed leak.

My intake gasket leaks coolant from the front of the intake. I resealed it and 10,000 miles later it developed again. Slower then before, a can of radiator stop leak fixed it though!
