oil in coolant help

hello

i have oil going into the radiator. i have flushed the radiator and it still seems to be getting in there i assume that i have a bad oil cooler i have taken an oil sample and sent it in and there is traces of coolant in the engine oil. i am worried about cavitation and i have done a compression test and all cylinders are in the 400s and i don't get any bubbles in the radiator. any ideas thanks in advance!!!

what he needs to do is a leakdown test and see if the cylinders HOLD compression. If not then its cavitation or a HG.
