I think the head is coming off soon!
At least it should pop off easily - not that long ago the HGs were changed!!!

I think the heads will stay where they are!

It cant be a bent valve, the compression is to good.

This, allied to the stiffness in rotation, does still suggest FOD inside trying to prevent valve opening fully.

Interesting.....just had a quick look.

The crank becomes harder to turn once the No 1 exhaust comes on cam.....and at no other point during the 2 rotations of the cam.

Found a few bits of sealer etc on the inlet valve (may well be un-related).


Interesting indeed.

The sealant might well have been me. I slapped the cam cover, manifold and plenum back on pretty hastily before it was moved.

Perhaps something in the valve train has siezed, although it's difficult to imagine how it would create enough resistance to the valve opening that it can be felt at the crank, yet allow the valve to close tightly under the force of the spring. :-/

Although being aware of you guys' professionalism, I do not think this can be the answer. :-/
