So do you think its just a quality control issue with the lifters? There are several articles on-line stating its a crap shoot when you buy them due to the # of suppliers

Lots of the lifters are made in China these days. I can't get US made solid lifters for a 235 six cylinder motor any longer. And yes, they do break.

Were they Mellings JB 2236?
How long had they been installed?
Is there anything that might have contributed to lifter failure other than poor quality lifter?

If so...what does Pete have to say about Mellings JB 2236 as they are as identical to stock lifters as you can get?
Lifters

Lifters
we use the same lifters,Bob and Pete think that the cams moved,and that started the train wreck.

Cams moved? You mean timing changed?
Such that you had valve contact with pistons?
I know it is close depending on head work, valve work, timing and Cams.....I had light (but you could see) eyebrows on all pistons on a set of heads not too long ago.

Yes that's what I mean (changed valve timing).

Maybe in October.
I think the cams started to walk to due to the shearing the rest is a train wreck of catastrophic events. Chain broke after all the bits and pieces ground the cams to a halt. Lifters shattered as they got in the way. Valves bent as all the pieces started to share the same space.

Very ugly Even when I lost my secondaries system the very small pieces bent 2valves.
