I really need some help here fellow jeepers. this is my second jeep i own now and i bought it for dirt cheap because of a blown head gasket.. its a 2000 jeep wrangler 2.5 4 cyl black.. the jeep before i started tearing it down would still start right up and run fine it would just throw water obviously. so a buddy and i tore down everything and got into the head gasket, yes it had the 0331 hairline crack. i bought a new head gasket, i bought a whole new cylinder head, put it all back together to the right torque new intake manifold gasket. but the rocker arms back on but the thing i think i messed up on is i didnt torque those, i just screwed them in until the spring just started compressing. idk if that matters. got a new valve cover gasket cleaned up the actual valve cover, got all the lines hooked back up.. new distributor cap, wires and plugs, new radiator with all new hoses, new battery. go to fire it up and the battery acts dead and has a hard time crankin, which i very well couldve left somethin on one night, but then when i hooked up cables it would still barely crank and it would sorta back fire on me, so i shot starting fluid down into the intake and same thing wouldnt even turn over on the starting fluid. i need help please! any advice about anything is well appreciated!
