As to the 1006 filter, John used to own the car before I bought it. He recommissioned it. He documented it beautifully. The pictures he showed of the filter pertain to that recommissioning. Evidently a previous owner had put on the V8 oil filter because it is larger. That is why there was a 1006 filter showing in the picture. I have the original oil filter but I have not reinstalled it because to me the V8 oil filter makes a lot more sense. So, I use the 1006 on this particular engine. And I think the previous owner whoever he was for putting on the larger oil filter.

The original oil pressure gauge and the auxiliary oil pressure gauge usually agree. I generally go by the auxiliary gauge because it's a lot younger than the one in the dashboard!

Great advice!

John,
Thank God for your pics!! You saved me a lot of work.
Weather permitting, I will take the car out on the beltway early Sunday morning for a high speed run. You would not believe the traffic! Rush hour now starts at 2:30!

I got my house to market too late this year! Off soon, then back on in the spring. I cannot wait to move....to many people up here! And Amazon in coming! Madness!!

Thanks!

I did not realize that but it makes perfect sense. Thanks!!

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.

The video!
