My 1996 Ek1 Engine Rebuild documentation.
Hey guys, just posting up some of the documentation of my D16Y4 rebuild.
The whole process took about 2 and a half weeks to get the motor running again as it took about 10 days to get the boss pipe which connects the water pump to the thermostat up. The job was mostly an DIY job (note im only 19 this year ;P) The job of taking the motor out was done at Racing Project (mitcham, victoria)
Reason of rebuild: Engine was drinking engine oil but there were no traces leakage as well as engine wasn't running as smooth as it should of been along with the need of a new clutch kit.
work done: Port and Polish done to the head, Block was sent out for a light hone as there were hairline scratches down the bore, New Rings and conrod bearings, thrust bearing, all crank bearings and big end bearings were fine.
Pictures are shown below on chronological order, enjoy.
First comes first, pics of the car ;D

Air Con compressor is taken off the engine so it stays with the car, proves to be a little bit more work but saves the effort for regas and other contaminants entering the system, hard to see in this picture but wiring loom to ecu has been pulled out and follows the motor alone.

Found the cause of the dissapearing oil, it was from the valve stem seals exhaust side leaking at a slow rate. all that black stuff took about 15mins each piston to remove. good old wire brush and part washer fluids.

4 pistons are in, (D series drivers, note how thin the conrods are) weighed the pistons and conrod's without the bearings in are about 669g each. all within an 1g tolerance.
