oil in coolant - Diesel Forum

shooter63 · 01-26-2009, 01:48 PM

my 97 350 is getting oil in the coolant. not alot, but its noticable. the truck runs fine and has plenty of power, but last week it started leaking coolant off the backside of the motor. i was told it could be the intake manifold gasket. any other ideas.

oil cooler or head gaskets

Hope it is just the oil cooler or the o rings for the cooler. Not tooo bad of a job.

My bet is on the oil cooler as well

If it's oil (leaking outside) from the oil cooler, it's the inner set of O-rings. If it's coolant, than it's the outer set of o-rings. If either is mixing than it's the outer o-rings....not that it matters. i'd hope you would replace all of them

I just went thru this last weekend. I've heard people say "you may have to jack the motor." I could see any other way but to jack it up about 1".
Pretty messy, but well worth it! I hear they get $600 from the Stealership to R&R the oil cooler. I spent a whole $40 to do it myself...not including the new oil and coolant.
