The seal needs installed before replacing the cover. Make sure everything is tight and clean, and place a thin film of oil on the seal before installing it. I usually use a small block of wood to tap it into place.

Let me know if you have other questions.

I have a 81 ford pu 4x4 302 4speed the timing chain and gears went bad put new one's in and went to start and nothing would fire we did not pull the vavle cover to see the valve's closed @TDC and believe it is 180 degrees out. Here's my question can I reset the distributor 180 degrees and rewire 180 degrees and would that save me from pulling it all apart

Take it back apart and make sure the crank and cam adjustment marks line up.

Then find tdc for #1 cylinder and see if distributor is pointing at the #1 cylinder, if not adjust as needed.

Engine Mechanical problem
1977 Ford F150 V8 Four Wheel Drive Automatic

We have a 400ci engine. It was running but seemed to have a miss in it. Now it won't start. The dist. Has spark to it but the rotor button does not turn. I pulled the dist. And it seems fine. Could the timing chain be broke?

That is very possible take off the rotor and have someone turn the engine carefully. Make sure that the shaft is or is not turning. If thats not it you can mark the distributor and pull it out and make sure the gear on the end isnt damaged.

Ok we had a friend tell us the oil pump locked up and broke the shaft. We replaced the shaft and oil pump. It started right up. And ran for about a half hour and then it did the same thing.L He said maybe the dist. Has a problem. Any help? Thanks blackop555 for your help.

Shouldnt be the distributor. Is the gear on the shaft torn up or in good shape? The distributor should turn just fine. If it was binding it wouldnt have had a issue asap. Oil pump properly set up and timed? Anything bent?

Just to add my 2 cents on this. Just make sure the distributor turns free when you remove it. I have these bearing in the distributor bind up and cause the shaft to bend. Eventually you will start breaking rotor buttons but it will work for a while but cause all sorts of different issues.

Basically all you have to do is remove the distributor and turn it and it should spin very free. If it feels tight then it needs replaced. Thanks
