I know there have a few posts in the past about these oil coolers but i thought i would share an experience of a friends truck.
A few months ago a friend noticed moisture around his oil cooler cover and also his past 2 oil analysis' showed a small amount of coolant in his oil. As of the past few weeks he's noticed the runnability going down hill, we tested the ficm and found out it was bad so it was replaced with a tuned piece from Ed i believe. After the new ficm was installed the truck seemed to run a little better but still wasnt 100%. So next we did a power contribution test on the injectors and found only 2 cylinders with no "counts" on the scanner, he bit the bullet and 8 new injectors were ordered.
Last night he starts tearing the truck apart to find the water leak is coming from and finds this (pics below) when he pulls the oil cooler out. Apparently the dorman oil cooler gasket isnt compatible with oil? Also the small handle on the screen had come off and was laying in the valley of the oil cooler. The screen was almost completely plugged from broken down gasket and unfortunately the screen did have a tear in it. My thoughts are the screen plugged then tore and now gasket material may have gotten into the injectors causing his problems? The truck was "bullet proofed" about 3 years ago he thinks, he couldn't remember the exactly mileage.
As for the cooler itself he said after 3 years it had a 12 degree delta but obviously if you do decide on an aftermarket cooler at the very least use ford gaskets.
Just wanted to share his experience.
