Oil pressure reading DB 116
Posted 09 March 2011 - 05:18 AM
The gauge, of course, goes to 4 pounds.
What reading would be too high, indicating blockage somewhere in the oil
tubing or strainer?

Here is a quote from the mechanics instruction manual:
"With new oil of medium grade the gauge should show a pressure of approximately one and one half pounds with the engine running at a speed equivalent to about 20 mph."
"The oil pressure should raise with the speed of the engine."
"If gauge shows excessive pressure, it indicates that either the gauge is defective, the oil is too heavy, the engine oil feed pipe holes plugged, or too much tension on the ball check spring."
"After car No. A875-380 (1927) the oil pressure shown on the gauge is controlled by pump capacity and the area of holes in the oil feed lines and may not show any pressure at low engine speeds. No pressure adjustment can be made on these cars. When the pump is working properly the gauge will show pressure at 20 mph and will increase with the speed of the engine. This will fluctuate according to the density of the oil."
On cars before 1927 the oil pressure can be adjusted by increasing or decreasing the spring tension on the check ball in the oil check valve at right side of engine.
Hope this helps,

The spring tension I do not know how to check.
What is the 'oil feed pipe' - is this the pipe from the pan to the gauge or some other pipe I should be concerned?
