My trucks distributor has always moved a bit when the truck is running, cant tell if its a side to side movement, or rotational, but it rotates, or moves.
that was my old distro, now out for rebuild.. I thought maybe the bushings being worn was the contributing factor to the movement.
Now I just installed the brand new NOS unit I received the other day and it too does the side to side/ rotational movement.
now I cant remember is ALL of my past trucks did this. I dont think they did.
at first I thought that the engine rebuilder might have re-bored the oil pump to distributor hole a bit non-ecentric causing this. Then I thought, is that possible? do rebuilders even touch that bore?
So what could it be, and is it common?
I am leaning toward perhaps a bent oil pump shaft causing this? any ideas?
My distributor is a NOS unit... I just installed, it, but if a worn or bent shafted oil pump may be the culprit, I wish to not run this brand new DIstro long for fear of wearing out the bushings (maybe)
