Ok guys quick backstory car ran great like new my dumb self accidentally went from 3rd to 2nd needless to say 3 bent valves 2 on passenger 1 on driver side. Ok checked all valves replaced the only 3 that were bent/wouldn't close up tight. Alright just got car back together hasn't been ran or cranked since last August car cranks up fine I'dles great car starts popping from driver side exhaust pipe,thought we found the problem was the hose that runs from the bottom nipple on the side of the throttle body runs to the Evap thing lol. Put it on car stops popping. Get everything buttoned up crank the car to go for a spin it idles abt a minute CLUNK! Car cuts off bent 3 pushrods both on cylinder 2 and one on the exhaust valve of number 4. Check everything notice the poly locks in my rockers look extremely backed out and I believe 3 of my pushrods were from another engine coincidence 3 broke? Anyways shot in the dark I buy 3 new pushrods put them in fire the car up idles and runs great I take it for a spin I don't go above 3k rpm runs good I get back let it idle and it pops through the exhaust again. We run through and double check all the valves everything's good. We watch the rockers with the car running all looks well BUT when you first touch the key to turn the car over the rocker on the the exhaust valve of the #1 cylinder doesn't move for a couple seconds? Last time I saw this issue I had an oil gally plug pop out and wiped the front 4 lobes off my cam -_- so here's my question what do you guys think my problem is here lol I'm at a loss and any advice is very much appreciated thanks guys
