GM 216 Engine Rebuilding.
Cool Chevy GM 216 engine we are rebuilding at the machine shop. GM 216’s were in production from 1937-1963, this engine is a 1950 cast iron beast.
Engine Rebuild Agenda: Teardown, Inspection, Bore and Hone engine block, Grind crank and cam, Valve job on the head, Install New pistons, rings, bearings, gaskets, timing set, clean, paint, and assemble.
Here is a Before shot, it’s time to tear it down.
As soon as we remove the oil pan we see where the problem starts. Somehow, material or a rag got into the pan and wrapped around the railing tubing and clogged everything up. Not good, the engine was suffocating.
Looks like the connecting rod dippers/scoopers may be bent.
Further inspection reveals a few more issues. Here you see we cleaned up the connecting rods and we see some damage. The engine block has a bad cylinder, check out that hole. Needs to be repaired, we will put a new sleeve in. We bore and hone the remaining cylinders and make them all the same size.

Fast forward and we are already assembling the Long block.
