Hello to All. My rebuilt 4BT 150hp marine engine may have had the pistons put in reversed 180 degrees, and not oriented with the combustion area on piston top with the injectors. It smokes too much for a new engine. Would it run with injectors aligned incorrectly, or would they hit the pistons? Capt. Tom would like to hear from anyone. Thanks.

Ask some folks in the aviation business to borescope the cylinder with an injector out (or through an open exhaust valve) to see what direction the pistons are in.
