I need some help I've had a misfire for a while and was pretty sure it was because i torqued the rocker arm wrong or something... now the book says tighten to 11ft-lbs +90degrees, but what i want to know do i have to have the valve all to the way open, or all the way closed? I did it with the valves all the way open, car ran ok could idle lower but it have been like that for a while. took it for a test drive runs good no misfire pulls real hard... on the way back just cruising i think now i have a valve tick.. or exhaust leak but leaning towards a tick... i just want to know the proper way to torque the rocker arms? thank you
