<VV> [fastvair] push rod failure [2 Attachments]

[Paul Fox]

I see this more and more. Not often at all on original engines though. And of course I  see this  more on Hi-Po engines with stiffer valve springs. I'm fairly sure it's caused buy small block type replacement lifters and or low ZDDP in the oils today. There just isn't enough oil flow through the small block Chevy lifters. Currently I'm saving all the original Corvair lifters I can find to send them out to be reground because I hate come backs.

While cleaning the inside of push Rods with a fine wire, the end broke off. Obviously it was fractured prior to the cleaning. Has any body had this happen. Rod was very clean and straight. Any thoughts?
