Re: The Duchess Project: 1940 Super 8 Convertible Sedan

My block was manufactured in August of 1940, so very late, my understanding is in the late 1940 blocks there is no return at the bottom only half way up the block, this is how mine is. So if I am understanding this correctly if I do not have the bottom return the two feeds will not work.
The reason I am getting clarification is I just had the oil canister off the car to make sure all was clear, which it was. The hole in the center pipe is very small and leads me to wonder really how much oil is getting returned to the block? Regardless of the filter being plumbed correctly or not. If you have been following my oil lines are correct, but this canister in showing outlet at bottom instead of top side of canister. (I am looking at a similar canister on ebay that has the outlet on side). And I just did a third oil change adding two bottles of some motor honey and let it run just in case there was some air someplace. Seems to have made no difference in the lifter noise. But, will run more tomorrow.
I can't imagine either why the difference. If you remember I had to replace one valve, and did a very mild clean up and hand lap in all the valves, which worked great for a couple hundred miles. Unless as stated now that they are worked in and just now out of tolerance and stem adjustment. I just got a gauge so if I do need pull the head can check valve stem clearance.
Thanks for all the help and keep the ideas coming in.
