I just installed my oil pump the other day and I am pretty confident I measured everything right and it was inspec. I spun freely when I had it out, but when I set it in and torqued it down to 80 inch lbs, the thing was too hard to rotate by hand. Is this normal? Should it take a good bit of force from the eccentric shaft to get it spinning? I just wanna make sure before I ruining a good engine and oil chain ;P.

Thanks guys
