I always turn things over a few times by hand to check for interference.
Just one of those habits that I'm glad I've developed. Haven't felt any
anything touching which might be because it's not really 90 degrees but
closer to 75 or 80 deg. Both timing belt gears have been changed but I
haven't taken them off to check them since the initial assembly. I should
probably do this though shouldn't I?

The good news is that I took off the valve cover to confirm that the cams
are timed correctly to each other and found lots of oil. The pump is work=
ing
and everything is pumped up nicely from all of this cranking.
