Is this common or no? THANKS!
It's not a big deal. The guide pin on the crankshaft needs a dab of RTV. Pull the HB, remove old RTV buildup without unseating the pin (for lack of actual name), dab RTV it and reseat the HB. If it leaks again use a bigger dab. The timing cover seal only seal the outside of the balancer shaft. The pin is on the inside diameter of the shaft.
