Thread: Common Engine Building Mistakes

Tweet

Our Techs at work do exactly that on every engine we install (and we use only brand new crate long blocks) because it saves a whole lot of work pulling it back out if a problem is found. Just last week a brand new 454 was prelubed and no oil was getting to the rockers..........we think cam bearings were installed off center. If we had installed it we would have had 20 hours labor go up in smoke.

the lifter galley plugs .are missing in the front of the block or if a gen 5-6 the1/8 plugs were not in the lifter valley for low oil psi the mark 4 to 6 do not oil thru the cam bearings if the cam bearing were not lined up you would just dry the cam out burn the bearing out and cam the the 1/4 front plugs out you will get low oil psi oil to cam and crank . but no upper oil from lifters to rockers
