Hey you're all good guys, most of you anyhow lol, but seriously.. lighten up.
The 1st post, the 1st pic... I viewed on my cell. If you viewed it on a computer and still thought it was a hard seat, put down the buddywiser and wipe the boogers out of your eyes. I still dont know for sure, who could when it's not in front of them, when you havent torn the heads down..what if it's an old pickup... full of hidden garbage from the previous disaster. How about somebody did a spring change at one point and magically lost two keepers into the engine and decided **** it... picked up two more... put the spring on ...n call'd it a day.
Btw pot calling the kettle black, Yellow.lmao

I did look at it on my iPad. And I had my glasses on.

I've broken probably 100 locks and had customers break probably close to 500 locks and never had one fail.

That's valves hitting Pistons much harder that the OP had. Blown alcohol Hemi junk eats valve locks like potato chips, especially if they float the valves.

That's one reason why I didn't say valve lock. They'd have to be 100% junk to fail like that with the spring loads and RPM the OP has.

Its a million times more likely a seat will fall out that a valve lock fail like that.

Plus, there was no reference as to the size of the broken parts.
