Oil in the Radiator

courtesy of Bob, The Auto Answer Man

Hi Bob,
As I opened the radiator cap, I noticed that a small amount of oil was accumulated on the radiator cap. The water in the coolant reservoir is also oily. What could be the problem and what is the remedy aside from overhauling? Is water entering the engine? Emission of smoke is noticeable especially during high speeds. I temporarily drained my radiator and poured in Whiz metal sealer. I'll observe it for one week.

It sounds like you have a head gasket leak. There are some products on the market that claim to be a pour in fix for something like this. However, I have never tried one, so I do not have any first-hand knowledge if they work or not.
Good Luck!
Drive Safely!
