well the main problem I had was the missing parts from the engine I bought and the difference of the 98 bonneville engine. I didnt find any information about the parts being different, or anything. I just figured they were the same. Its my fault I know it is, I'm just glad everything is straightened out right now and looks like it might shape up ok. It was a good tear down anyway, we found the head gaskets leaking and LIM gaskets leaking... its a 6 year old car, but still, at 48000 they shouldnt be that bad.
