So the status report....
Pulled the radiator off. There is more oil in there than Saudi Arabia. It's really bad. It's old oil too. Flushed it with water. Then with Simple Green. Shook it up. Let it sit. Flushed again. There is still a ton of oil all over the fins. (I'm taking it the radiator shop tomorrow to get it pressure flushed).
Pulled the oil cooler off. Looks pretty good. There was some particulate in the core, so I brake cleaned that, slipped on the new O-rings, lubed em up, and put it back in. The old O-rings looked fine in my opinion, but I'd rather put the new ones in, see if the problem comes up, if not... Hey, I got some o-rings for the future.
I cleaned all of the hoses and I cleaned everything I possibly could get off. I ran the truck for about 20 minutes today with the Simple Green in the coolant, gonna flush that out in the morning. Put in some of the Peak Cleaner/Additive, run it for a bit. Flush that, then fill it with water and take it over to the radiator shop.
On a side note, however, I kinked one the return line from the radiator to the transmission. Scale of 1 to 10, how FUBAR am I? Here's a picture:
LAST Point. In speaking with the diesel tech at the dealership (who seemed pretty knowledgeable), he said I may be having a water pump problem. That the pressure on the crankcase is causing pitting and forcing oil into the coolant. I wonder, though, with the pressure going up and down in the block, on decel, wouldn't coolant get sucked into the oil? And there's ZERO coolant in my oil. Thoughts, opinions, help!? Anything would be appreciated.
