Malleus
Far west of Siegen
Just finished what may be the longest headgasket replacement on record, on No. 1 son's 1995 80. Started on the first try, and no leaks. However (isn't there always a "however"?), while walking around, looking and listening, I noticed a ticking sound from what appears to be the distributor area, or within a couple of inches of that, anyway.
Charlie leans in and says, "it's the belts on the crank pulley. It's wobbling and the belts are running around and falling back down in the grooves after they try to climb out". I don't know if that was the source of the sound, but sure enough the edge of the pulley is wobbling, by about 1/32" or so, just enough to see, but apparently not enough to make any other noises. Yet.
The problem is, it's his truck and I don't look at it enough to know whether this was happening before his headgasket took a dive, or not, and if it was, for how long. It bothers me, in addition to the fact that the flanges (at least) seem to be wobbling, since the bore, AFAICR, is pretty long, the I can't remember the flanges being pressed onto the hub, but maybe they are. So, I don't think the hub itself, and thus the balancer, is wobbling, I think (I hope, really) it's the flanges that have worked themselves loose.
Has anyone seen this before? Am I wrong that the flanges are pressed onto a hub, which also has a balancer on it?
