525's oil in coolant

I have a small amount of oil in the coolant tank. Engine oil seems clean. What is normal oil temp when running hard? I am seeing 220 both sides. Thanks

Re: 525's oil in coolant

I have the same issue and I've been told by the experts that the oil cooler is raw water cooled, not antifreeze. My engine has passed all the basic coolant leak tests and so far haven't deemed it necessary to do a full leakdown test. But the headgasket issue had been brought up. I have been keeping an eye on it but my engine is still running fine. At WOT I see about 200 or so on the oil temp and about 150 crusing around.

Re: 525's oil in coolant

there is a recall on the head bolts on SOME 525's and the coolant leaks that might be the problem.
