My cousin has a 350 Chevy engine that has in 190 miles since rebuilt,bent at least 2 pushrods bad and now has a cam with 2 lobes worn off.They were not on the same cylinders that had the bent pushrods on.The story. He called me a few days after he got the truck back from the his mechanics shop.It was running rough.I checked it out.It was missing on 3 cylinders.pulled the plugs,gas run out of the cylinders,because of no fuel filter,and the needle and seat on his new Eldebrock carb stuck open by dirt.I replaced the plugs fixed carb,started it up,dead miss no 3 cyl,pushrod bent and fell down in lifter valley.Removed Intake ,no3 exaust lifter pushed out but no damage to it.I replace the pushrod and re adjusted all the valves and changed the iol and filter.Cranked it up ran perfect for 190 miles,then he called me Saturday and said it was ticking on the right bank but was running good.later that evening he called back after going for a short trip the ticking stopped but now a dead miss.tore back into it,now no 6 intake pushrod bent.replace the pushrod and adjusted the valve,cranked it up and now no 6 exaust valve not moving.His mechanic removed the cam.lobes worn off of no 6 exaust and worn bad no 7 intake.I would like your opinion about what caused these problems.This engine is a 350 flat top with Comp cam 292 H and their lifters pushrods and roller tip 1.5 rockers.601 305 heads.My theory is lack of lube at the top end of the engine,possibly cam bearing not lined up right that caused the damage,most likely lifters seizing up?Whats yours?
