Had to edit after discussing it again w/ my dad.. sry not to up on the lil details of the motor! Well.. i was doing a hill climb.. and then i didnt make it, rolled back down and i heard tick tick tick tick tick,, i said ****,,, valve.. but then it sounded more like header gasket, so i replaced that wasnt it. Today my dad came over and we took the valve cover off.. it seems to be the #2 cylinder, we were playing around w/ the torque on the rocker arms and it went away for a second then would come back. My dad is saying prob a lifter thats messed up. This motor was supposed to have only "30k" on it according to my friend who i bought it off, it was a crate in 96. Sat for a while, bla bla anyways, what are my options, some cost ideas. My dad was saying if i killed a lifter, and have to take the heads off might as well do a head job etc. I dont know much about the cost or what u can and cant do in this kinda situation. If it was gonna cost me like 600bucks to do head work, and risk some other part of the motor going i might as well get a crate? sry for the long rant, just kinda lost on what to do. any ideas? advice?
