Pictures of Cleveland that dropped a valve

Thanks for the information and pictures! Now I can show the wife what could happen if I don't replace my heads! Maybe the bigger bill of replacing my entire motor will convince her that the heads are just a drop in the bucket!

Dang, and that was just the exaust valve. If the intake had done the same thing, it woulda blown completely to pieces.
It makes me wish I had taken pictures of my fragmented engine on a what not to do story.

Just a word to the engine newbies that are here.

The two piece valves (stem and head) are what Ford used as stock. And yup, they break at the joint where they were 'connected'. When you redo your engine's heads, make sure you upgrade to Manley or whoever single piece valves, usually Stainless Steel. Under no condition, even just a street motor, should you use OEM two-piece valves.

Could a cylinder liner be fitted to fix the cyliner wall damage?

My #1 cylinder looked a lot like this when I dropped a valve at our local road coarse several years ago. Valve was embedded vertically in the top of #1 piston when I tore it down. In my case we were able to sleeve the cylinder that was cracked & has been running great ever since - "knock on wood", even after going to closed-chamber 2V heads & kicking the compression up to about 10.5-1 from 8.5-1. Best to rely on your trusted machinist who has rebuilt a lot of 351c's for this decision.

Let me know if it works Dennis so I can try that one out on my wife....
