So at around 262k my 2001 f250 had some really bad UOA with very high wear metals and coolant in the oil.
I decided to get a used block, had it machined and rebuilt it. Front cover looked fine, new injector cups and new oil cooler.

Rebuilt engine has about 18k on it now and I did a UOA and it looks like I am still getting coolant in the oil. I am about to loose my ****. What else can I do to keep the damn coolant in the radiator on this truck?

Truck is used mostly to tow 10k pounds in the rocky mountains.

Thanks for any help.

Oil cooler is a big one

Given you replaced the oil cooler and the block/ heads- the front cover is the only other possibility. No other place it could cross over. Did you get a whole new oil cooler or just the center section?

Not sure what you mean by the "whole cooler". I replaced the everything except the end caps that bolt to the block.

By whole cooler, I meant a new assembly with new end caps as opposed to just the center assembly reusing your old end caps which theoretically could have a crack between the oil and water passageway.

What do you mean by the whole cooler? I replaced the tube assembly.

They make one that comes with new caps and tube put together all new.
