I have a suzuki rg 125f that once belonged to my brother. My father and I went to put it back on the road after a year of sitting in storage, the first thing that we noticed was that there was oil sitting on top of the radiator water so we took the engine apart but found no carcks in the main block or damage to the gaskets. Is there something else that it could be that we have overlooked. Cheers :confused:

When you took the head off were the nuts loose? Any cracks in the head gasket?

No they were still tight took abit of leverage to loosen them

No cracks in gasket as far as we could see

Hrm are you possitive its engine oil? Id check if the coolant hoses go any where else there could be oil or if a housing gets close to where the oil is :)
