Oil pressure and mult-viscosity oil.

I started using Rotilla T4 in my 1947 Clipper's 356 cu inch engine. A well know Packard specialist informed me he was using in one of his Packards and it helped quiet down the engine. As my car has some noisy lifters I started using it as well. It did have a significant effect in quieting down the engine.
Around town, the engine has always consistently shown about 40 lbs of oil pressure .
Recently, I had some work done on the car which included having the OD repaired. I drove home, about 1 1/2 hour drive, and was able to easily travel at 65 MPH with the OD engaged. As I got close to home, I noticed the oil pressure had dropped to 20 lbs...I do not know when this started during the drive as I was watching traffic.
A few days later, I drove the car around town and (45-50 mph) and the oil pressure was at the usual 40 lbs.
When I start the car, the oil pressure briefly spikes to 50 which is caused, I think, by the effort of filling the oil filter canister.
My question is would the OD lower the engine RPM so much that the oil pressure would drop to 20 lbs? Or does the 15w-40 oil have some effect here.
As the oil heats up, it becomes 40w...thicker!! That should increase oil pressure, if at all.

Thanks Fred! I'm pretty good about keeping mine at 42 because tires are a very expensive item and I don't have to buy another one!

The Diamondback people told me to use 42 lbs. This is because they happen to have in stock the exact duplicate of my original tire size tire but in a radial. Had I been alert, I would have gotten a "fatter" radial tire. I think they look better.
The profile is pretty skinny. In other words if you look at it from the back it's a very narrow Tire. So I think that's why they suggested 42lb. Bicycle tires have extremely high pressure because they're so small.

When I put on my new DiamondBacks, I was told to keep the air pressure at 42. So, I put on the steel valves and was very pleased. The tires rarely need additional air. I will start using them for all my cars!!

The Customs were low production which makes sense as they were top of the line!! Grab that specimen. Its glorious 356 9 main bearing engine was just rebuilt..49K original miles.

I had a problem similar to yours. My car started cold but not when hot. After weeks of frustration, I discovered it was the ignition switch.

Re: 1940 carburetor rebuild - Super 8

When I looked at the instructions for rebuilding my Carter carburetor on my 47 it appeared that one needed a lot of tools which were graduated to minuscule small diameters. I did not want to buy a set of these micro tools so I just sent mine to Daytona carburetor and they did a great job.
Frankly, I don't see how a home mechanic can rebuild a carburetor correctly after reading those instructions. But, I am one of those people that knows just enough to be dangerous.
