Hi John, block was not line honed at all. Both dowel pins are there for the rear main housing. I finally received a brand new OEM rear main seal yesterday. I put it in the housing and mounted it to the block. Same thing, the outer lip does not touch in certain spots. I even made sure the seal was pushed all the way down into the housing. I flipped it around backwards and the inner lip(the one that actually does the sealing), does touch all the way around. At this point, i'm just assuming that the outer lip is only a dust cover and not necessarily a lip that holds back oil. The inner lip(the one that you don't see) is the one that has the spring going around it on the inside of the seal.

I just now got the motor in the car about 45 minutes ago. Somebody PLEASE tell me I'm right on the above!!!!


EDIT: I found this on a non DSM site. It does not say anything about the outer lip holding back oil.

".....the rubber inner lip of the seal rides on the end of the crankshaft and keeps the oil inside the engine. There's a spiral-wound circular spring around the lip of the seal to help keep tension against the crankshaft."
