In the past, I've read where others, including myself, have experienced
a loud snapping sound, like an electrical arcing, just after the engine
was started. When checking my valve clearances a few months back, I
discovered both of my spark plugs were little more than hand-tight from
the factory. Fortunately, even after 7500 miles, the threads looked
fine and there were no signs of leakage or damage to the threads.
At 1st, I thought maybe it was just a coincidence. But, after
approximately 5 yrs. of snapping, almost every time I fired-up the
engine cold, since tightening the plugs, I have yet to hear the
infamous snapping or arcing sound. For those of you who are
experiencing this phenomenon, if you haven't already done so, you might
check your plugs.
