It's really hard to tell what's really in there unless someone has a dead one that they can cut open and investigate. What we see outside is usually mostly dirt anyway, so it's hard/impossible to tell what the viscosity of the stuff started out as. > I agree with you on the qualities of oil as an insulator on stationary > equipment, but on a small, high vibration part? It seems that if the tar > leaks out over the years, it must be really tough to keep the oil in there. If it is really filled completely, then there's no sloshing, and the guts gets supported by the boyant force of the oil/tar, so it's still pretty well situated, even with vibration, but I agree that the tar might be better. Anybody got a dead Bosch coil that they would care to saw apart, or send to me and I'll saw it apart and let everyone know what I find? - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Search old messages on the Web!
