oil in the coolant

new to the forum.. lots of good stuff here... long story short, my ? is I was pulling a camper home (about 500 miles) . I put oil in before I left and as I was almost home I noticed oil on the ground. it was coming from the coolant cap. I have had this on going problem with the oil cooler so there was oil in the coolant already. awhile ago I changed the o rings and had it flushed but was still small amount of oil in the coolant. so,after I pulled the camper I checked the oil and was a quart low!! the temp was fine. can the cooler itself go bad and push that much oil into the coolant? asking cause I just ordered a new cooler and rings. need to be back on the road Monday!! help

Yes. The cooler can go bad internally. I could've saved you a lot on a new one as I have a practically new one with housings for sale on here.

99.99% of the time the cooler itself doesn't go bad, just the O rings get brittle and leak.

If the big outermost one cracks it'll leak oil on the ground. If the small inner one does, it'll leak oil into the coolant.

Mine was left so long by the previous owner I've had a hell of a time flushing all the oil out.

the ford garage did it once and 1 year later it did it again. I asked what the problem was and that they needed to fix it. 12 month 12k mile warranty on the cooler. well I was 5 days past the warranty and they wouldn't cover it!!!! *@$(*&W@ .. so later on I pulled it and replaced the rings but they looked fine? sooo, not sure how the cooler goes bad but I just ordered new cooler, gaskets and rings. gonna flush the hell out of it and see what happens.

It could also be ur gaskets if they reused the old ones.
