Found your problems then and a valve not seated ! its still a good price though

 

Figured I'd update the thread. 12 bent valves probably due to water injection. Machine shop is fixing it now

 

Honda valves? care !> as seem to remember non oem may fail !

 

Water can't compress so it ended up bending valves

 

Hydro-locking it normaly bends rods..would suggest they did not close and pistons touched and distorted them.

 

Rods all checked out luckily

 

How would hydrolock bend valves?

Valve open, water just pushed back out cyl.

Valve closed, something else gives (rods bend, block cracks, etc).

What is scenario where water bends valve? Unless its not hydrolock, like maybe sudden cooling effect causing metallurgy issue?

 

Sounds like valve miss-timing issue?
