99 Grand Am, 3400 motor:
I just finished a head gasket/lower intake/upper intake gasket replacement. It ran well for a while, but then developed a loose rocker arm. I took the valve cover off and tightened up the rocker arm closest to the belt end of the engine on #2 cylinder. Its still making quite a ticking noise and misfiring.
Prior to the gasket work, this rocker arm had come loose and made a heck of a racket.
The threads in the head and on the "stud" are in good shape. I put it back in and used correct torque.
Does this sound like a bad lifter? what is making the rocker arm come loose? I put it back in with some locktite, I may regret that.
Is it possible to change the lifter out with a magnet....lifting the old one out and putting a new one in through the rocker arm gap? I think there is some kind of metal bracket in the way....I dont want to tear this thing down again if possible.
