the worst thing happened!!! bad.

Well I sold my 88 lx to my friend and he has had it for about a week. It needs a rear main seal and he knows that. Well today I went over to his house and he told me to listen to it because it was ****ed up. It sounds like pushrod tapping three times louder. I told him to look how much oil was on the dipstick. I was like 2-3 inches above the full line. He then told me that he added like two or three quarts of oil because he though that it was burning oil bad. Well it must of not been burning too much oil if it was that far over the full line. He didnt even check where it was on the dipstick before he filled it.
This really makes me mad, because I loved that car and I didn't want to get rid of it in the first place. But anyway we were trying to figure it out and someone said that it might be the main bearings, but I dont see how adding too much oil would screw them up. Also we took the valve covers off and he started it and no oil was flying out(shouldn't it be flying out?) And through the small hole in the head were the oil is supposed to come from smoke comes out of it.

If any of you guys could tell me what it might be, it would help me out allot.
thanks.
