Hi Adam,

With your engine vacuum reading I would be confirming the valve timing is correct.

Timing appears ok (from what i can see of in cylinder waveforms could be wrong?)


I have not had a chance to look at your in cylinder waveforms.

Was the timing set using the timing tools ? this engine does not have key-ways on the cams. I suspect the valve timing is out on one bank.

Regards
