I paid a company , to rebuild my engine, big mistake, I have ALWAYS dun it myself, but this time, I for any number of excuses, turned the project over to a outfit that was purported to be one of the best. I started the engine and the rear main leaked, but only till he engine came up to temp, then it stopped? I pulled the engine last Thursday and this is what I found:The rear main cap where it metes the block was not sealed , the seal was not rotated prior to install, easy fix, but why was it done half way? The most disturbing find came when I noticed the pan not fitting properly, the custom pick up lay right on the bottom of the pan!But to make matters worse, they fixed the problem by drilling random holes around the pick-up! This of course would allow ANY foreign material to go right into the pump and through the engine destroying it!Luckily I pulled the engine after one oil change and their was no damage. BE WARE, do it yourself!
