V.Milke Posted December 24, 2003 Share Posted December 24, 2003 My '41 Continental's gage shows almost 50 pounds of oil pressure when I start it, but they gradually go down as the engine heats up. After a good while, oil pressure at idle is cero, but as soon as I step a very little on the gas pedal, it goes up again to about 15. Is this something to be concerned? A second question would be: I just took the oil pan off and cleaned everything, including the fuel pump, which looks fine but shows a little wear marks. I remember reading in the past of a replacement for the oil pump which would rise oil pressure in the engine. Can somebody tell me if such a replacement exists and where to find it?Thanks,Victor.

Guest imported_V12Bill Posted December 24, 2003 Share Posted December 24, 2003 Victor, Oil preasure should read 20# at 50 MPH. Low readings at idle are not uncommon and of no concern as long as idle periods are not prolonged espechially in hot weather. Alan Wheilahan sells a High Volumn oil pump for about $250 or you can use one from a 49-51 Lincoln V 8.(Some minor modification needed)As long as you read + l5# at speed, I wouldn't worry. Alan's pumps will probably read about the same preasure that you already read. Remember his pumps are high VOLUMN not high preasure. Bill Link to comment Share on other sites More sharing options...
V.Milke Posted December 24, 2003 Author Share Posted December 24, 2003 Bill:Thanks for your response. According to your description, I don't need to be too concerned, as oil pressure rises as soon as I step a little on the gas to about 15 pounds. However, I would feel better if oil pressure at idle would show at least 5 pounds or so. You mention the high volume pumps. Are there any high pressure pumps?Thanks and Merry ChristmasVictor.

Guest imported_V12Bill Posted December 25, 2003 Share Posted December 25, 2003 Victor, These oil pumps have always been described to me as high volumn pumps and distinctly not high preasure. Someone once said to me, do you prefer a lot of oil at low preasure or as scant stream at high preasure? The logic seems to be that I would prefer a lot of oil.

Rolf Posted December 25, 2003 Share Posted December 25, 2003 Hey Victor, the Melling 19 replacement oil pump is recommended highly in the flathead V-8, they are at least 80 lbs, and may have more volume too, V-12's lose OP through the hydraulic lifters, so a improved pump is helpful, Rolf Link to comment Share on other sites More sharing options...
V.Milke Posted December 26, 2003 Author Share Posted December 26, 2003 Thanks Bill and Rolf for your responses. I have heard very good words about the Melling pump, but I will try to do my homework and ask around before I decide myself for it. Link to comment Share on other sites More sharing options...
Guest 40-41 connies Posted December 27, 2003 Share Posted December 27, 2003 If you do not have a mechanical oil gauge, buy one and hook up the line to the inlet that your oil pressure sender is located. This gauge will give you an accurate reading on your oil pressure. I had the same problem as you and used one I purchased from NAPA to test with and my oil pressure was 8 to 10 lbs higher than the senders reading. For test only.

Rolf Posted December 27, 2003 Share Posted December 27, 2003 One common problem in this area is the oil sending unit. There are two varietys intended for the 50 and 80 lb oil pressure guages used on the pre and post war cars, using the incorrect one with the wrong guage will give you strange readings indeed. The senders are usually stamped 50 or 80 on the bottom of the unit, Rolf Link to comment Share on other sites More sharing options...
