1990 F150/5.0 oil pan removal
 

Is it possible to remove the oil pan without removing the engine?

Thanks
Richard

yes. You will need to remove the upper plenum and y pipe. Then unbolt the engine mounts and pick up the engine as far as it will go.
Unbolt the pan and snake your arm in to unbolt the oil pump. Everthing will come out then

Thanks Brad, That was exactly what I was looking for.

Richard

it is a little more involved then that.

clearance between crossmember and pan an trans. is "o".

radiator shroud needs to come off.

other tips if you do an advanced search in this forum.

Thanks QL2.
I already suspected the fan shroud. The fan clutch is FUBR, so I'll just remove it and leave the fan in the shroud. That will take care of the fan hitting the shroud.

Thanks

If you are trying to replace the oil pan gasket you do not need to remove anything. Unbolt the pan then wrestle the gasket in. The oil pump pickup is difficult to get under but it is doable...assuming this is what you want to do.

Its actually really easy to take off the pan if you have access to a lift,
don't forget the four bolts on the bottom of the timing cover

The old truck has 100,000 miles on it. When I fire it up, the mains bang until the oil pressure comes up. The the oil pressure will drop to almost zero when hot, at an idle. The ol beater will get less than 2,000 miles a year, hauling limbs and trash. I intend to roll in a new set of mains, rod bearings and a new oil pump. You would be surprised how long a set of bearings last on a less than perfect crankshaft. I've done this before on old engines with success. Thanks for all your responses.

Been there , done that a few times too. Helped a brother-in-law do that years ago in his Ford van, 2 of the original rod bearings actually spun on the crank. He put another 60,000 miles in that old van till a king pin froze & tore of the tie rod end.
