Engine Oil Pan Removal

I have pulled the pan on '91 f150. Which is a pickup of the same exact body style. It was also 2wd, had the V8 and the auto trans. The oil pan will clear the crossmember, however in order for it to do so, you need to unbolt the engine from it's mounts, loosen the tranny mounts, disconnect the exhaust at the manifolds and jack the engine up about four to five inches for the oil pan to clear.

The oil pump and pickup tube sticks down into the oil pan quite a ways and you won't be able to pull the pan out unless you reach up in there and unbolt both and lower them into the oil pan.

Make sure the crankshaft throw for #1 cylinder is at the top of it's stroke (TDC). All that should give you the room you need to remove the oil pan. I hope this helps.

You will have to remove the front engine mount nuts and raise the front of engine with a jack and wood block. This should give you the clearance to remove the pan.

Have you removed the oil pump and tubing for extra clearance?

This is on a 4.9L engine, correct?

Sorry about that, whats your email and I will send it to you so you can open it up and enlarge it through email.

Have you removed the fan and lifted the motor until it contacts the firewall?

Hi
Engine must be traised at least 1" off mounts. Also rest oil pan on cross member remove two bolt holding oil pump let pump fall into pan remove.
Thanks for donate

Yes, remove the torque converter dust cover (metal plate), unbolt the engine mounts, loosen the tranny mounts, and jack up the engine 4-6 inches. You have to do that so the oil pan will clear the crossmember easily. Make sure everything like the fan shroud and stuff will clear before you jack it up. I hope this helps.

What pan are you talking about. Engine oil or tranny?

Make sure no wires are preventing engine from going up. Also make sure radiator fan isnt hitting radiator. Try loosening up tranny mount and other motor mounts to gain additional clearence.

Yes, you will have to lift engine. Here is step by step how to replace oil pan.

1.Drain the crankcase.

CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

2.Drain the cooling system.

CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

3.On 1987-93 models, remove the upper intake manifold and throttle body (see Fuel System ).
4.Remove the starter.
5.Remove the engine front support insulator to support bracket nuts and washers on both supports. Raise the front of the engine with a transmission jack and wood block and place 1 in. (25mm) thick wood blocks between the front support insulators and support brackets. Lower the engine and remove the transmission jack.
6.Remove the oil pan attaching bolts and lower the pan to the crossmember. Remove the two oil pump inlet tube and screw assembly bolts and drop the assembly in the pan. Remove the oil pan. Remove the oil pump inlet tube attaching bolts. Remove the inlet tube and screen assembly from the oil pump and leave it in the bottom of the oil pan. Remove the oil pan gaskets. Remove the inlet tube and screen from the oil pan.

To install:

7.Clean the gasket surfaces of the oil pump, oil pan and cylinder block. Remove the rear main bearing cap to oil pan seal and cylinder front cover to oil pan seal. Clean the seal grooves.
8.Apply oil-resistant sealer in the cavities between the bearing cap and cylinder block. Install a new seal in the rear main bearing cap and apply a bead of oil-resistant sealer to the tapered ends of the seal.
9.Install new side gaskets on the oil pan with oil-resistant sealer. Position a new oil pan to cylinder front cover seal on the oil pan.
10.Clean the inlet tube and screen assembly and place it in the oil pan.
11.Position the oil pan under the engine. Install the inlet tube and screen assembly on the oil pump with a new gasket. Tighten the screws to 5-7 ft. lbs. (7-9 Nm). Position the oil pan against the cylinder block and install the attaching bolts. Tighten the bolts in sequence to 10-12 ft. lbs. (13-16 Nm).
12.Raise the engine with a transmission jack and remove the wood blocks from the engine front supports. Lower the engine until the front support insulators are positioned on the support brackets. Install the washers and nuts on the insulator studs and tighten the nuts.
13.Install the starter and connect the starter cable.
14.Install the intake manifold and throttle body, if removed.
15.Fill the crankcase and cooling system.
16.Start the engine and check for coolant and oil leaks.
