Mountainman,

On the front of the engine there are three seals. You should probably do the whole shot. That is, timing belt, belt tensioner, and all three seals. You might consider a water pump as it will save you some time/trouble to do it at the same time.

Yes, you should have replaced the rear main, but if you had to button it up to move it you didn't have much choice. I have had to do two rear mains at about 150k miles, and my new 940 with 140k will probably need one soon. However, if the oil is dripping out from the back of the pan instead of the at the trans/engine joint, then maybe it's not the rear seal. Might be the pan or just running down from above.

I think there is a half moon shaped rubber plug back near the distributor under the valve cover gasket that might be your leak there, or it could be the valve cover gasket. I have a vague recollection that I saw a distributor seal as a listed part, but don't know if it was for the rear distributor or for the distributor in the block style.

You should probably check out your crankcase ventilation system because if it is not working it can make many oil leaks all over. I think that is covered in the 700/900 FAQ section.
