The idea is to keep nasty crud out of the IPR. Inside of the cavity is a cheap screen filter that does not rival the quality of one of those bad window-unit AC filters. Engine must be stripped basically down to a long block in order to get at this thing. I also recommended the installation of a coolant filter and Rotella ELC NF as well, since no amount of flushing was ever going to completely eliminate garbage from that cooling system.įor those not familar with this engine, the oil cooler is a liquid/liquid type that is bolted into a cavity in the center of the valley between the cylinder heads. He was fortunate that someone had enough sense to do an EGR delete, otherwise the EGR would have self-destructed and taken the engine along with it.Īfter much consideration, conversation with my guys, and deciding I would assist them with that turdpile myself, I recommended a Ford OEM oil cooler, IPR, and IPC replacement, as well as replacement of the pigtail at both sensors, since they are known culprits. Flushed a lot of rust out of the system!". I called him up to get a history of the truck. Presence of rust, as well as oil in the cooling system. It took all of about 25 minutes to note a distinct gap between Engine Oil Temperature and Engine Coolant Temperature. I sent one of my trucks to pick up his truck, and proceeded to diagnose the issue. In the meantime, he was bleeding cash renting a truck at a prince's ransom. I didn't want to sentence any of my guys to that nightmare either.Ī few days later, he contacts me again to tell me that all of the other shops he contacted gave him 5-figure estimates to fix the truck. Sounded to me like a blown headgasket, and I did not want to listen to bunch of complaining that I can't separate a truck in half and replace half the engine for $10 and a box of FunDip. I know enough about Powerstroke 6.0's to know I wouldn't want to touch them with a 10 foot pole. 6.0! Good, no?".Īt first, I turned him down. Most unfortunately, he told me the engine was a "Ford. He said had a refrigerated truck that was mixing oil and coolant. A fellow delivery business owner contacted me for assistance.
