appears to be motor oil in radiator. Talked to Luke and a couple other 2 stroke guys and the concensus is that it's probably the oil cooler. What says those in the know? Can the contents in the radiator be tested to see what is in the water-antifreeze ? Thanks everyone!

I would say the oil cooler remove the cover and have it check at a radiator shop if you need a core I have a freebee core here from Red Ryders engine you pay shipping
good luck
Of course they can be tested.
Go to DD, get a sample kit, follow instructions.
By the way, Clifford has already given you the most probable cause.
I would think the oil would also be contaminated after shutdown water pressure would be higher than oil pressure and would cross flow

He will need to change oil and he better buy him a big box of Cascade for a dishwasher it will take at least 3 times to clean the mess out of his system
Thanks guys
Luvurbus, you said to remove cover and have it checked. I believe its on the inside or towards the firewall in the GM. Will probably have to remove it and have it checked. Just last year the tranny cooler leaked oil into the radiator. Keeping the radiator from rusting.

Yep no easy way to remove it from a GM just roll the engine out where you can get at it easy
