Ok, today is the beginning of my troubleshooting, to discover why this engine is mis-firing. I've been on nightshifts, so I will need a bit of sleep, but hopefully will get some time.
Jobs for today are, in this order:
* Remove Aux belt, and remove timing cover. Check that the valve timing is set spot on and that the belt is OK. Remove the bolts from the Camshaft pulleys, and ensure the pulleys are engaged in the correct keyways. Remove the cambelt and adjust if necessary (I hope I don't have to)
* Check the presence, and condition, of all the spark plugs.
* Compression test, (if it arrives today) to determine any possible internal issues. (I can turn the engine over with the switch without the barrel being installed
)
* Get an ignition barrel assembly and key, so I don't have to keep bump starting it!
* Attach strobe to each HT lead, and find out if it's missing on any particular plug. Investigate as necessary.
* If at this point I've discovered nothing, time to look at other issues, such as crank sensor, cam sensor etc.
But to be honest, it sounds so nasty and is pinking so much at high revs, that I don't think it's a sensor.
Time will tell, I will be posting up the results.... I must just keep reminding myself that this engine has likely been thrown together by monkeys that don't know Vauxhalls from Adam, so I'm really not going to be able to assume anything and must not overlook the obvious....
