Oil or Gas in cooling system
I have pro-charged 502 Rage. Set it up 8 years ago with AZ speed & marine. Has been totally reliable and bulletproof. Maybe 450 hours.
I noticed a petroleum sheen on shutdown as raw water cooling drains from intercooler dump (raw water draining down from block through intercooler and out). I'm not sure if its oil or gas. What is most likely source? No water observed in oil (milkshake). Blown head gasket? Failed oil cooler or cool fuel? Where to start? Seems to be running fine.
Thank you all in advance for any suggestions.

A trip to the hardware store to buy a 3’section of appropriately sized hose and 2 barbed couplings to bypass the oil cooler solved my sheen investigation. After installing the bypass contraption the water was free of sheen.
