RE: 390 Oil Pressure Improvement
By Allan - 10/23/2002 9:55:38 AM; IP 12.13.226.18
.....verified oil pressure is really low.....

The guage in the car only has an L and and H for a range reading so it doesn't actually give a pressure reading. At idle it goes below the L.
I screwed another pressure guage into the sending unit hole above the filter and it reads below 10 psi at idle. The pressure comes up to about 35psi max at about 3000rpm which is acceptable but lower than what I would expect. I threw a can of STP in it and the oil pressure immediatly came up to about 60 psi. This tells me that viscosity is helping to close up the tolerances and improve pressure readings. Which leads me to believe that things inside are pretty worn. The STP pressure improvement only worked for about a couple of days, which I don't understand but just tells me that STP is not the answer. I'm going to change it over to 20W 50 oil next and see if that helps. (Now running 10W 30). As I mentioned earlier, my goal is to change to the new engine in the spring so I just want to hold this engine together for a while longer.
This thread, so far...
