Title: 1934 Blue Star inlet valve oil feed and oil pressure gauge pipe diameters
Post by: David Samways on 15 Aug, 2022, 18:02
Could someone tell me the diameter of the pipe that feeds oil to the inlet valve and that which connects to the oil pressure guage?

Thanks, David

On my '35 the valve guide pipe is 3/16 od and the oil gauge pipe is 5/32. The rear pipe I am reasonably confident about being right. The oil gauge was a bit of a guess judged upon the squashed remnants that were in the union on the timing cover.
