Hi...
We took the motor out of my 93 F150 but before my neighbor helped me and we were successful I had some difficulty pull the engine myself. When I attempted it myself I removed all six bell housing bolts and disconnected all wires and cables. Hooked the motor up to the hoist elevating it and rocking it back and fourth and it wouldn't come out. I got under the truck to see what the problem is, and saw one side was coming loose but the other side wasn’t. The image shows were what I thought was the problem. I thought a rusted out alignment dowel

 

Looks like you still have to unbolt the exhaust pipe too.

 

Thanks for replying
This was my first post and I did some thing wrong. I tried to have it taken down but no luck, anyway the exhaust is cut on both sides so engine is free and out now. As you can see I damaged the hole thinking is was a rusted alignment dowel stopping me from pulling the engine. I was gonna ask if could put weld in the cuts and beef up the hole then run a tap?

 

I wouldnt worry about it, that thing is in rough shape....
Youre suppose to loosen the 2 trans mount nuts at the trans crossmember & slide the entire trans back till the trans mount studs bottom out against the crossmember,
The trans will slide back about 1".......

Assuming you had a floor jack on the trans to support it while you lifted the engine out??
You want to crank the front of the trans fairly high.....
then lift the engine....

 

An alignment dowel wouldn't prevent the engine from separating from the trans. They are too small and are not threaded preventing them from seizing things together that hard.
The engine to trans bolts go through the dowels which sit in a counter bore. Most of the time you have to watch you don't knock them out of place when getting it back together.

I wouldn't do anything with that bolt hole except chase the threads.

Check for bolts that you may have missed, be sure the flywheel/flexplate is unbolted. Be sure you are lifting it high enough to clear the motor mounts depending on how they are made, sometimes it doesn't matter.

 

As rough shape as that engine is in inregards to rust....
Sometimes the bell housing / engine alignment dowels get stuck in the transmission,
The need to be hammered out from the backside using a punch & re-install in the back of the engine.

They hold the inspection plate in place.
