Help! Front oil seal question
I am doing a front oil seal on a 302. I noticed the seal sits over the crank snout key. Is this normal? Is the seal supposed to keep oil in even with the key sitting inside spinning around in the seal? I need to put everything back together, but I would hate to do it if it is not right...
Please help!

It will, but the harmonic balancer goes on and the outside of that rides on the seal service, which by the way you can see where the seal has been riding on the balancer, sand this area down and clean it up.

Oh, so that seal will 'lift up' when the balancer comes in to place? Cool! Now, the seal itself... It seem that the flat steel flange of the seal slightly hits a part of the timing cover if I try to push it in. I am pressing it from the inside. Should this be a big deal?

Wait a minute... I found the directional arrow in the seal, so it has to go on from the outside in order for the engine to rotate clockwise like the arrow... Am I on the right track?

There is a flat metal side with the seal "lip" pointed out, that will be facing out on the timing chain cover. The opposite end will have open end and you can see the interior seal. The front of the seal, the flat part, is probably painted, This will be facing out. Just make sure putting on the balancer you don't push the seal service in. You can put a little bearing grease on the balancer to help it slide into the seal better.

Thank you, you've been most helpful! The seal install went well. With that flange on the outside, it definately works out with the directional arrow. I just wanted to double check the installation, in case it was done before but done wrong, as the seal was busted up all around. The neoprene material was dry and cracked up and the spring was exposed all over. I fine sanded the snout of the balancer to get rid of some old garbage that was caked on. There are some small grooves in it, but I hope it will not effect the seal. It was quite a job getting all the accessories off! A/c, thermactor pump, alternator, power steering, etc..
By the way, this isn't even a truck! LOL It is an '83 Lincoln Continental. I kept the waterpump intact so I didn't have to replace those gaskets. I just removed the pump and cover as an assembly. I didn't even have to pull the rad to work in there! I had plenty of room to clean the stubborn old gaskets off the block. I found that the old seal was an actual FOMOCO part, by the writing on it. I should post a picture of the old seal! Quite a mess... Well, back to reassembly! Thanks again, and wish me luck!

One thing I am having trouble with... There is only so much play in the timing cover before inserting all the bolts... And the seal doesn't seem to be perfectly centered around the crank snout. Nothing I did could bring it center! It is sitting a little to one side and a little low... Do you think this will cause a leak? I know that somewhere out there is a centering tool... But do you think I could find one???
I have heard many people installing these seals without the tool, and no troubles. Should I expect the same outcome?
Thanks,
Mark

I tried just slipping the seal itself over the balancer snout, and when done backwards, the seal won't slide on. It wants to bunch-up instead... The right way, it slides on like nothing...
