Re: Head Sealing Problem?

So...

I have always contended that the liner height is critical.  Indeed I think what 
really matters is the loaded liner height.  Is it possible that liners can 
fatigue or for some unclear reason settle in the block to a lower level once 
loaded/compressed?  Possibly measuring ok unloaded but, compressing to 0 deck 
height once torqued? 

I think there is a pressure sensitive material that can be placed upon the 
liners.  Once the head is torqued down and then lifted off an indication of 
compressed contact is visualizable.. different colors represent different 
contact pressure.
