I did a full valve adjustment on Monday and all went fine using the no-go go method. Except for one valve.

On cylinder 3 intake side, right side as you look at the intake. I could adjust to a 0.009" gap with the aim of it being a correct 0.008" after torquing the locking nut with the feeler gauge still inserted prior to measurement but the adjustment bolt kept tightening further (and messing up the gap) while torquing the adjustment nut. After much messing around it appears that the adjustment screw just kept tightening and seemingly bent the feeler gauge as if there was no resistance for it to push up against.

The rest of the valve for cylinder 3 adjusted as expected without any problems at all.

Is this a cause for concern? Seeing pictures of cracked retainers showed that the valve stem would start to drop lower than it should, could this be what is happening here?

I ended up adjusting to a 0.013" gap and torquing the locking nut which gave me a good 0.008" gap but I think it needs looking at.

What are peoples opinions?
