FYI... My old guage pegged at the top all the time, too. For some reason, it no longer does this with the high-output USADMC engine. When cold, it pegs near the top, and when warm it cruises in the upper/middle of the range and idles near the bottom. It probably helps that I'm using nice, fresh synthetic oil and not that rancid, 60-million-year-old gunk. :-) Gus Schlachter Austin, TX 4695 > > This is the way the stock O.E.M. oil presure gauge seems to work. > You can watch the oil pressure with a mechanial guage to verify the > engine is O.K.
