so i just performed a valve adjustment to my 86' 2.7L ETA engine
i adjusted them to the factory recommended .25mm tolerances and it ran like a charm until i drove somewhere
one of my rockers (the fifth intake) started to tick, it seemed like it had loosened itself up once i put load on the engine
so this morning i took the cover back off and checked the tolerances of the rockers around the tick, it was the fifth cylinder's intake like i said before
i readjusted it and even ran it for a few seconds with the cover off to hear each one better and it was almost dead quiet
but once i drove it, the same rocker lobe loosed up and is ticking again
what can i do about it and what should i check?
what are the lobes on the rocker ends supposed to be torqued to?
and do i need a new rocker?
