Oil in coolant

[MARSOC MARINE]

I know this issue has been beaten to death but, I'm curious to know what I'm getting iol in my res? My 00 v10 , shows no signs of fluid loss, (oil or tranny) , neither of which is milked ( both are uncontaminated ) plugs look good, no loss of power, no white smoke idling or under load, zero signs! It's got 127k. Idles smooth, runs great. Anyone got any suggestions for me? Thanks

Oh, btw, did compression test, all cylinders are within spec! I'm stumped?

Check trans fluid. Might have an internal rad failure. Pressure test

Probably wouldn't hurt to do a leak-down test. Its usually more telling than a compression test.

I bet you're burning it and don't realize it
