Flathead pre-oiler - good, bad and the ugly?

[Ziggster]

Posted this on the HAMB earlier today, and so far no responses, so decided to post it here as well.

Decided last week to fab up a pre-oiler to use on the first start-up on my C59A. Hoping to start it for the first time in a couple of weeks. Some background. Engine was rebuilt (short block) back in 2019 IIRC. I didn’t get around to doing the final assembly until 2023-2024. I used Permatex Ultra Slick engine assembly lube on stuff I assembled like oil pan pump and cam gear. Has 5 quarts of Lucas 5W-30 Hot Rod oil in the pan.
Since it’s been sitting for so long, thought it would be a good idea to somehow pre-pressurize the internal passages. My understanding with flatheads this is impossible due to the distributor drive config (I put a helmet style on). So, the idea of a pre-oiler. Got this old air tank and modded it. Tank has crude/rust inside so added the Ford style remote oil filter. Now wondering does this make sense. Will the filter trap all the crude inside the tank?
