Mark - are you talking about
oil pressure or
oil temperature? I believe the
oil pressure gauge just has oil in it while the oil temperature gauge has ether in it.
My oil temp gauge went out recently and I have a replacement one that I have not yet installed which you could have if that would get you going today. I bought it at Nosingers as the repair wasn't a whole lot cheaper than replacement. I understand it does take some time to re-run the line from the engine to the dash and one must be careful not to kink the line.
Can you just rely on your water temp. gauge for today?
Just my 2¢.
Hope you can make it - Tom
P.S. No longer raining in Burlingame - should be fine for this evening.
