Re: 1936 oil pump help
I presonaly thing 10-30 oil would be the best bet. That way all the oil that comes out of the pimp goes through the bearings. remember this is a positive displacement pump. AS for the pressure gauge, leave the line off the gauge until all the air is out of it. I run 5-20 in a new engine. get 10lbs at idle and 40 at 2k.

Re: 1936 oil pump help
How do you get to this front plug? I can not seem to find it on any drawings. I did try bleeding the line to the gauge, it did not make much of a difference.

Re: 1936 oil pump help
Air in the fuel gauge line will not change the gauge reading, the air just compresses.
The plug is 18-6026-A Plug, Cylinder Block Oil Line 3/8-18 Pipe. It is inside the front cover at the end of the block oil galley. It is shown in the engine block illustrations. Note: the same plug is also used at the rear of the galley. Last edited by JSeery; 08-01-2015 at 05:54 PM. |

Re: 1936 oil pump help
The way to find the pressure loss without taking everything apart is to make a pressure pot to feed oil under pressure into the gauge port, then (with the pan off) see where it comes out, bearings should only have drip, keep the pressure under the 30 lbs or so that opens the front valve
