Replaced the spring when I did the pump. Oil is 20W50 Castrol GTX.
Rings were installed correctly.
Am beginning to believe that I have a bad oil sending unit. There's
evidence of leakage on the sending unit, and the light comes on earlier
and earlier in operation. I''ve got a T-fitting for both an oil pressure
guage and the sending unit, earlier today it was coming on with the
pressure reading 25-30 lbs, tonight it was on at 40-45 lbs. The guage is
accurate.
The fitting is threaded the same as that on a Chevy small block or six
cylinder, and as I recall, these were set to come on at 25 lbs pressure.
Can anyone think of any reason why I can't use one of these units to test
it with?
