long story short, i wanted to get my pickup IMM ready. done all the welding, brakes etc. been off the road since January 1995. i had it running briefly in 2013 and it seemed okay. but on getting her running last weekend, i had hardly any oil pressure (from cold) and also there was an awful rattling from the bottom end. so i thought quick fix, to swap for a modified 1100 i have in the garage. engine has fantastic oil pressure, & pulls like a train. but smokes like a trooper. I did look into using some slick 50, but after reading on here i don't think it'd be a good idea.
So my question is, is there anything i can do, other than keep topping the oil up constantly. just to get through this years show season, before i take the engine back out and rehone/rebore?
