Merry Christmas and Happy New Year to all!
I need some advice! I have a 1990, Ford PU, F250, automatic, 4X4, 7.3 idi, non turbo. Occasional driver, so being down for a while isn't an issue and I have the time to do it right.
I've developed an oil leak an inch or 2 above where the oil filter spins on. When the engine is running, I get a constant, approximate 1/8th inch stream of oil squirting out the back (rear axle side of the truck). Shut the motor off it slows and stops, so it's under pressure only. I downloaded engine diagram and think it's coming from the back head of the rear oil cooler head but I need a better look to tell if it's a gasket failure, crack or some kind of port. I plan to power wash the gunk off, start it up (I'm only about 1 qt low so I can do some diagnostics with out running dry) and try to get a better look at it. I'll upload pictures this weekend when I clean it up if needed.
My experience, lots of general repair and replacement on gas vehicles but this is my 1st diesel.
What do I need to know before I dive in? Is there any ports on the back side of the back cooler head that could be my issue? It doesn't seem like it's up against the block so I don't think it's a gasket but I haven't cleaned it up and inspected it close enough to be sure?
If it's a head crack, are they available anywhere. It didn't seem like a listed part in any site like RockAuto when I was looking for diagrams.
I've downloaded a video on replacing the cooler unit and other than getting everything out of the way it seems pretty strait forward, famous last words.
Thanks for any and all counsel!
