Broken pushrod in 1995 Z28.
Going to work last week, doing about 60 mph, I suddenly felt the engine go off song, then a lot of tapping noise. Limped home and parked it. So here's what I have: 135,000 miles, and about 25,000 miles on a comp 501 w/ Isky springs, full valve job, magnum roller tip rockers, and stock hardened pushrods. The broken pushrod snapped at the weld. Looking at it, it showed enough wear that I think the head got into a restriction at the rocker and maybe a weak weld allowed it to break off. I now have a set of Comp one piece magnum pushrods, and plan to install the full set tomorrow. My question is: do I have a freak incident, or have others had the same thing happen too?
