All,

I'm currently building up my 320 engine. Seems to be going ok so far; I have the crank and camshaft in (with bearings obviously) which are prelubed with engine building paste. Also rear main seal installed. I left a slight amount of interference on it by cutting it with a box knife blade laid flat.

I noticed this rotating assembly so far takes 25ft lbs to move from a standstill, and 8 ft lbs to keep moving. Is this normal for a NEW seal, or did I leave too much interference?
