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. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

I also got mine used with close to 70,000 miles on it, have owned it now for close to 8 years and may never get rid of it! I did replace the stock transmission with a 700r4 overdrive that gave me a whopping extra 7 mpg in the city, and raised the top speed of the truck to well over 150 mph!
