didn;t remove motor. just fan and shroud, crank pulley, balancer and timing belt sprocket and whatever else is involved in a timing belt change out. there is a assembly (for lack of a better word) that the seal goes in that also seals to the front of the oil pan.
I ended up taking that off that assembly redoing all hte gasket and reinstalling. Then pressing in the seal. I tried once with the seal in but couldn;t get the new gasket to the assembly to quit moving and ended tearing the crank seal. leaving the crank seal out left a little room to set it back on the oil pan.
I pressed the new seal in by cutting a piece of 2" PVC pipe to about 6" long or so to push against the seal and using a long 2x4 to push on the PVC using the sway bar as a fulcrum point (think 2nd class lever if you don;t get what i'm typing).
hope that helps and wish i had pic's, they always help. There is a trick posted somewhere about using drywall screws to pull out the seal if you don;t remove the "assembly".
My timing issue.... I'm just gonna throw the truck in the shop and let a mechanic figure out my problem. to hot right now to be f-ing with it and nobody seems to know here.
