Front main seal

[dougc767]

Or timing cover seal, whichever, ..replacing mine in a '91 and there's 2 different types. One has a flange (lip) the other doesn't. Will both work? How about the one with the flange, does it get pressed in from the front of the timing cover or from the back? Thats the one I got from the parts store but the old seal is the one without the flange. Much obliged.

get the one with the flange seal a timkin or national brand hopefully and it gets pressed in from the outside, u can use old seal to press in new seal.

i havent used it but i think either work. that extra piece is used if the crankshaft has wear and doesnt seal properly

On my 89, I was given the one without the flange. As long as all other measurements are the same, can't see why the flanged unit wouldn't work.
Both go in from the front.
-Make sure it goes in straight and not cocked.
-Use a large socket to drive it in. I use a seal driver. Block of wood works.
-I try to avoid hitting the face directly with heavy hammer blows.
If you do have to hit the face, tap around the perimeter evenly.
-If you pack it with grease it will keep the spring in place as you reinstall the harmonic balancer.

The repair sleeve goes on the harmonic balancer, and seals the harmonic balancer and timing cover. I didn't see where he got that kit.

Thanks all, I'll press it in from the outside (flanged one). Happy Thanksgiving!
