Oil pump change
I checked on here for something about this, but no luck. On my 88 F150 4.9 2wd, how difficult would it be to change the oil pump with the engine still in the truck? Can the engine be lifted up high enough without taking it right out?
The reason I ask is because when I start the engine, it takes a few more seconds than normal for the oil pressure to build up, an when it does, a hot pressure is about 7-10 psi. When the engine is shut off, and I watch the mechanical oil guage I put in bleed-off, the pressure drops off slowly, which to me means that the bearings are still o-k in terms of clearances. I do have another 4.9 for the truck, but haven't taken it apart to check it's condition, and I need to move by the end of April so I don't have time to change engines.
Any help would be appreciated.
