Bad Oil leak!!!! 96 F250

[cbrumley]

I checked the oil the other day and was 2 quarts low, odd the old truck doesn't burn any oil normally. Yesterday I replaced a failed starter and noticed where all the oil was going. Out the driver side back end of the motor. I snapped a picture, looks like the oil is coming out of the cylinder attached to the oil filter housing. Any ideas?

That cylinder is your oil cooler (a tube/shell type heat exchanger that uses engine coolant to cool the oil). There are two sets of large O-rings on each end to seal the coolant and oil. Also make sure that it isn't coming from something like the High Pressure Oil Rail end plugs on both ends of each head (plugs are o-ringed sealed about 2" in diameter with 1/2" square-drive recesses). Cheers!

Thanks for the responses!!! I snapped another picture of just the oil cooler. The leak is not coming from the oil pan seal on the back of the block, the leak is higher up than that. I think that this picture shows that the leak is in the oil cooler. So if this is true advice on replacing the orings/gaskets?


Or is there a plug on the side of the block im missing?


Thanks Again



Leak is on the driver side of the truck.

I did mine last year not that difficult probably took a 2 hours from start to finish, hardest part was prying the tube out of the rear fitting. If I remember right quite a bit of oil was still in the cooler so you will need to either change the oil completely or replace what was lost so make sure you have some on hand.
