Answer 1

The L28 engine is the most common Z car engine. Removal of the cranshaft is staight forward. Sans the steps required to pull the engine from the car, with the engine mounted on an engine stand, the steps are: 1) Remove all exterior components from the engine. (Alternator, starter, water pump, intake/exhaust manifold). 2) Remove main pulley 3) Remove front engine cover. Requires the removal of the distributor, oil pump and pump drive shaft from cover, first. 4) Drain engine oil, remove valve cover 5) Remove engine head: remove cam sproket, chain, head requires a 10mm hex drive to loosen head bolts. Lift head from engine, set down on side, being carefull not to damage the valves. 6) Rotate engine 180 degrees, upside down on engine stand. 7) Remove oil filter, oil pan, oil pick up tube. 8) Remove rod caps from crankshaft. 9) Remove crankshaft main caps. Frint and rear main caps are most difficullt to remove and require leveraging these out of the machined surfaces. Be carefull not to damage the mating surfaces. 10) Crankshaft should lift out of engine block.
