The crawler has had some occasional hard use but sits most of the time. Recently I got it cleaned up and running after sitting a year to take to a local fair. The water pump gave out and when I drained the antifreeze there seemed to be a good bit of oil. Doesn't appear to have antifreeze in the oil. Any ideas of the cause? [Reply]   [No Email]

Could anyone have added oil by mistake to the coolant or possible vandelism? Maybe there is actually nothing wrong other than contamination. [Reply]  [No Email]

Since the anti-freeze had not been changed, only checked for freeze and fill level the last twenty years I suspected it was probably an environmental time issue. I steam cleaned the water jacket and radiator out real well but hated to put it all back together if there was some other underlying issue. I put a brand new head on the engine when I did the restoration but I assumed I would have anti-freeze in the oil if the head/gasket was the problem. Thanks again for the input. [Reply]  [No Email]
