I thought that too but checked and cyl 1 is tdc when all marks are where they should be.

even if it was, wouldn't it at least try to fire, albeit very roughly?

A mate can borrow a Launch x431.  Hopefully get it from him at weekend. I'm going to try some other tests in the meantime.  Also got another cam sensor coming, just in case.

I'll update on progress.

ok folks.

I now know why it's not starting, but am at a complete loss on how to proceed.  There is no compression!  25psi on cyl1, 0 on the rest.

The cam buckets are all out again and feel very stiff, even though I primed them in warm oil before putting them back in during rebuild. 

Any thoughts?

right.

mate and I had a look again tonight and tested by filling cyl 1 with air from my compressor.  Air could be heard leaking out but we couldn't find where from.

stripped the head off again.  all valves seated nicely.  surfaces of head and block checked with straight edge - all ok.  the gasket looked fine, the only thing being it was a cheapo from flebay.

so - new (better) gasket and bolts tomorrow and will be checking compression before proceeding with anything else!

I'll update on progress.

Just take your time when refitting everything and make sure you follow correct sequence for tightening head down. :y

might be about to send the mega to the tip.    :'(

new gasket and bolts bought this morning.  spent rest of day rebuilding and when tried to start - nothing, just cranking away but not firing again.   

timing checked and all ok.

compression test shows ZERO.

anybody know what else would cause this?

the rest of the car is near perfect too, I've spent a lot of time and money keeping it ship shape.
