Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Just stuck on 2 things, getting the A/C off it's bracket and moving it aside (so I don't release the gas).
Any idea what caused the problem ?
Well after a week of wrenching in the garage until the early hours of the morning has finally paid off, got the engine in and fired up around 10PM.
Primed the oil pump with vaseline, turned the engine over by hand to make sure nothing was siezed up, hit the key and it sprung to life within 5 seconds and got oil pressure instantly.
Was a bit concerned the first 3-4 minutes of it running as the top end was very rattly but I suspect this was due to the engine sitting for so long the lifers had drained out and needed time to pump back up correctly.
After 5-10 minutes of running it up and down between 1000-1500 rpm the engine is now quiet as a mouse and smooth as silk.
Not bad for a donk thats been sitting untouched for over 5 years. (Low km ex VS Senator engine and remanufactured/aftermarket converter)
Tomorrows job is to tidy up some wiring, set the correct base timing, bleed the cooling system and she will be right to hit the road again.
