My 97 F-350 Rebuild/Repaint Thread
#273
I did put the melling HPOP on though, which runs a slightly higher pressure, so it's conceivable the cooler could have sprung a leak. I can't think of any easy way to test it once it's off either...
I do have the other cooler on the old engine I could use. Maybe I'll buy the oring kit, pull them both and decide which one to put back on...

Not from what I read. That would be fuel in the water.
And oil in the fuel is bad injector o-rings.
It seems to be pretty clear cut based on pressures - what fluids go where when different things fail. This is all based on research alone though. In open to any other opinions that might be out there. Definitely want to make sure I'm fixing the right thing here!

Agreed. I did an oil cooler on a guy's truck a while back that had just been rebuilt by another guy. Oil was getting in the coolant on his too. I pulled the freshly rebuilt oil cooler apart and one of the o-rings was rolled over the stop. He must not have lubed them enough when he put it back together.

After this initial sinking feeling that I had an injector cup job ahead of me, I'm feeling better it's hopefully just the oil cooler. Parts are in the mail and I have fri and sat to sort it out.
I've been driving it the last few days and checking the coolant each day. The level hasnt rise any more and there's been no spillage. As long as I don't ride it hard and hot it seems to be ok. I guess that means it's a pretty small leak or that it only opens at full temp.

thanks a good point. i've been checking the fluid level every time i shut it off, so i'm bleeding the coolant pressure at that point. i'll be sure to keep doing that!

good to know, Nate. its about time i rig up a bottle jack press in the shop anyway, but might as well try the lean-on-it-method first...

Scroll down to the oil cooler bit. Seriously it's easier than leaning on it.
