The headline says it all. My car is a 1946 TC. I removed the oil pump and checked it out, all seems OK. The pressure/bypass valves are clean, no visible wear or broken gear teeth. I lapped the cap/body faces before rebuilding.
I had the sump off once to replace the front seal on the crank, so I took the opportunity to clean out the oil pick up. It makes me wonder if I did something wrong.
I know that the sump gasket isn't blocking the flow as I can insert a flexible plastic strip into the oil feed and push it quite a way down, certainly past the junction of block and sump.
I'm wondering if the oil pick up is supposed to have a one way valve or something. There certainly wasn't one when I took it out. The Moss catalogue and the workshop manul don't have any diagrams that I can refer to. I'm reluctant to drop the sump again before trying all other solutions.
