I've been running straight 30 to try and slow an oil leak. Would thicker 40 weight lead to higher or lower oil pressure? My pressure starts out a little above the "L" when I start the motor at first but after awhile, when the motor is hot, at idle the oil pressure is off the gauge its so low.
Run over how to test the gauge again. I understand pulling off the wire to see the gauge reads low, but to ground the wire to the sender, do you mean run the wire that normally goes to the sender to a direct ground? And that should make it read high? Sorry for all the questions but I really wanna get this thing workin right.
On a good note, I got some of the bounce out of the speedo. I tried to straighten the cable as much as possible, no kinks. When I turned the cable by hand at the T-case I felt a little springy resistance through half of one revolution of the cable. I still gotta get some of that graphite grease and lube it up.
