im replacing the head gasket and a few valves and i noticed while taking off the harmonic balancer that it had resistance in only one spot as i turned it. i repaced all the gaskets and some valves that were burnt, im on the reassembling part now. before i torque the harmonic balancer back i turned the crankshaft to see if the resistance went away and it didnt. my book says that it might be that the valves are contacting the pistons but i dont think so cause it was like that before i did the job, and i dont really want to take the cylinder head back off because the bolts holding it down are one time use stretch bolts $150 for new ones. Any advice

i assume you have the timing belt on. there should be resistance in 4 areas as you turn unless you have the plugs out. did you do a compression test to verify that there is no more valve failures??

i havnt done a compression test yet, and i dont hav any of the sparkplugs in yet. i just put the timing belt back on and i understand that it has 4 points of resistance form the camshafts hitting the rockerarms for each cylinder but this resistance i feel is more than nessasary. i hav a compression tester but i dont know how to test it without either running the car witch i cant do yet or pumping air into the cylinder head with i dont have hav a compression tank.

just install the compression tester and crank the motor. it should be 150 or better.

okay ill try that but from what you said earlier i think im just dumb. i went back out and timed wher the resistance was in accordance to witch rocker its hitting and all i was aparently feeling was the resistance from each rocker so im sorry to waist your time with all that. i will still try the compression thing though to make sure. i have one more question. my spockets hav the word up on them, when they r positioned up that means they r (tdc) or top dead center?and is that the position i should try starting the car in?

there should be a mark on the cam gear. if not then the keyway goes straight up.
