I shut it down, checked the gauge, a stewart warner, and it moved after i pumped air into it, ran it with the oil pump boss open with no oil coming out. I finally took out the distributor and primed the pump with a drill and allthread rod cut for the pump. It spun freely for a few revs but then caught and i could see oil going up the oil pressure gauge tubing with pressure now reading on the gauge. I ran errands on the truck all weekend with the usual 10 to 15 lbs of oil pressure no problem. Could this be a sign of future trouble or is this a common occurance???

Also, if you have an oil filter, sometimes the air trapped in the top can act like a spring, taking a moment to compress, before the gauge starts to move. Remember, the rods are getting oil, as they have the dippers.
Are you right up to the "full" mark? | | | | | Joined: Jun 2010 Posts: 1,001 Shop Shark | | Shop Shark Joined: Jun 2010 Posts: 1,001 | Remember, the rods are getting oil, as they have the dippers. Is it true that the dippers are picking up oil if the pump is not filling the troughs? | | |
