DIY Crank Shaft Pulley
Re-installing the crankseal on the oil pump cover is fairly easy. Grease up the seal and use a block of wood, or a large socket and tap it in until it's flush to the surface.
Installing the oil pump o-ring is just like a valve cover gasket. If you really clean out the groove with a paper towel, the gasket will stick in there just fine. Don't stretch the rubber o-ring or it won't sit correctly. If you need, you can add some silicon to make it stick.
When you put the oil pump cover back on, be sure to line up the tab in the oil pump gear with the crankshaft.
Getting the cover tabs and gear tab in place takes a little patience, but it does go on. Sitting on the engine makes this a little easier!
The pulley can only go on one way because of the keyed pulley. You can apply a little bit of oil or grease inside the pulley to make it slide easier on the crankshaft.
Rotate the pulley until the key fits properly on the crank shaft.
Tighten the pulley bolt to 137 ft/lbs. Putting the car in gear should be enough for you to tighten the bolt.
From here on out it's just a matter of putting the pieces back together!
When you put the belts back on, be sure to not overtighten them. There should be about 1" of play in the belt and the belt should be flush with the top of the pulley surface. If the belt is below the surface of the pulley, then it's too tight!
To prime the oil pump, disconnect the main HT line going from the coil to the distributor. Then let the car crank for about 10 seconds.
When you start the car for the first time, watch the oil pressure light. If it doesn't go out within 5 seconds, then you messed up the install of the oil pump!
If everything went well you should have a look like this...
