Driving on 5 cylinders

[kschachn]

I used a feeler gauge. All of the other valves are fine. It's the one particular valve where I replaced the rocker arm that had been broken. It continuously gets tighter and tighter with each rotation

Rotation of what? Your lifters are rotating?

Does it look like this?

Yeah it looks like that. And me hand rotating the engine. Initially I put it all back together and the car ran rough/stalled/rich. Took it all apart again to find that valve tight as hell. Readjusted it, rotated it by hand 5 times. Tight again.

This is one on the side that has 3 correct?

 

[deadcylinderman]

It's one of the number 4 cylinder's exhaust valves

First one from the left. The second rocker arm I replaced was missing a roller

I’d wonder what the lifter and valve look like that had the broken rocker? Chances are things got chewed up pretty good. Maybe worse?

Going back to the first broken rocker arm and why it broke and now the new rocker arm tightening for some reason is a tough one. I think it may have something to do with the mechanism on the intake side, it seems like something is catching that exhaust rocker other than its designated cam lobe.
I would remove the intake side valve train and watch the new rocker arm as you slowly rotate the engine.
