After jerking the oil pan and the stock cast-iron intake, we found clues as to why the engine was removed. First we spotted a lifter retaining clip (A) in the oil pan, which explained why there was a lifter’s inner plunger (B) lying in the lifter valley. We figured a flat cam lobe and wasted lifter (C) caused both problems, presumably the result of improper cam break-in on this otherwise new engine. Then we found the bent pushrod (closest to the foreground), thanks to a long exhaust pushrod having been installed where one of the shorter intake pushrods was supposed to be. What jokers. We later found a mystery chunk of unknown "oops" (D) under the valvespring with a retainer (E) that was chewed up badly.
