Thanks Jay and Pete.

Pete, what do you "read into that"?

I was hoping Spud still had the cylinder head.

It shouldn't be too difficult to have a lab do a hardness test on the valve seats.

I suspect my RX3 engine has a similar condition, in addition to other problems.

At ~8,500 miles both intake valves went to zero clearance within 1,000 miles. The lock nuts on the threaded adjusters were still tight.

My RX3 is from the second US shipment.

As of now, I have decided to "test the engine to failure".

Then I will open it up to see what is going on.
