You got there and that is the most important thing, be thankful it was the 1-3-5 bank out as if it was the 2-4-6 it would be head off again
Always remember, if you have fuel, spark and compression, the engine will run IF the cam timing is correct......hence having got to the point of confirming those three it had to be cam timing.
A few quick additional checks to prove the loom was ok and then a simple check of the cam lobes and diag done.
The thing is, I actually made two (really silly, and avoidable) mistakes during this job.
First one - fitting the G-cam on the exhaust side, and the J cam on the inlet, on the 1-3-5. This is what caused the original 1-3-5 misfire and dodgy idle.
It was after finding this fault, and swapping them over, that I THEN made the mistake of putting the inlet cam in the wrong keyway!!
I was actually thinking on the drive home that perhaps I should have a break from working on Omegas for a bit. But - actually - I have never made any such mistakes before, and have rebuilt lots of these V6 top ends, and whilst I'm at enthusiast level, as opposed to professional level - the reality is I'm probably as competent and equipped as most small garages to do engine work on these.
So, the show goes on, I am going to continue with my own 3.2 project, which has been sat all winter gathering dust. The only thing I'm going to do differently is not put myself under any pressure to get it done quickly, instead just doing a little bit at a time, and enjoying it
