Message: [QUOTE="elrodalexander73, post: 1131979, member: 16217"] And I'm talking good push rods, if you're breaking good push rods like smith bros you've got a serious deflection issue, did you ever yank the head to see if there was any piston to valve contact, I've seen the fulcrum ball bearing area wear severely from poor maintenance on 7.3s especially in cold weather areas where owners fire them with the oil cold and hammer down. I've ran stock junk on mine with 250/200s for 20,000 miles now and no problems with a junk D66 and right at 40lbs of boost and not a single issue, I built it two years ago, myself, had it balanced by EVI in Swarts Creek Mi, and assembled it in Tn, hardly ever even use glow plugs to start it. If your busting push rods you need to find the root cause, not rule out too much power, or valve to piston contact, if you're having contact you need to check seat pressure, again.. I'd be leary of lifters too not pumping up properly or when under load with boost holding them down (pressure against the valve to keep it from opening) that may have caused the rockers to snap. Swamps actually sells modified lifters that prevent this condition that causes pushrod deflection and rocker failure.. [/QUOTE]
