ok as some of you know im having a problem. ok first ill tell you how im pretty sure it happened. i was moving my truck to the other side of the driveway so i could get a rolling frame out of the shop. well i got it to the other side and it died from a fuel problem. so i went and moved the frame, cleaned the shop, and pushed the frame back in. well it still wouldent start so i went inside. well my mom got home (im 18, i split the rent with her) and told me to move my truck and i said it wont start and she said i dont care. i have crap in my tank so after it sits it starts(im fixing it when my fuel cell gets in). well i get in and it starts and by this time it had already been a Really bad day so i floor it and let off the clutch and spin all the way back to my spot and killed it. stupid i know and it wont happen again. well i went back out and started it and it was missing. well after setting the valves i discovered it has a flattened lifter(or a bad spot in the cam). im buying 16 new lifters and installing them tomorrow, but whats the odds the cam is bad too? i know its the number 5 intake lifter thats bad and also that its missing on 5 because i pulled the plug wire with no difference in running. anyways should i go ahead and replace the cam while im at it? im still quite new at this so any help is appreciated. now i know what happens when you do stupid things. anyways thanks ahead of time.
