We had a Ford E series ambulance with a diesel in it that blew out the pan gasket. Had to remove the engine on that one to do it too. Imagine getting a diesel out of a van.
We have the Diesel in our Ford van school bus` and believe it or not if you pull the trans and raise the engine front and back we do the pans in them without pulling it. The dealer was shocked to hear we leave the engine in.
