You can't? Let's see:

What's the problem, Skuzzy and Madmaxx? That was just the IMG link from my Photobucket account. Looks like it worked OK to me.....:3DSMILE:

Dugly :cool:

.

It's actually pretty easy to understand once you see how the oiling system was designed, that is, main bearing #1 has a direct feed from the main oil gallery, but the for the oil to get to main bearings 2-5, the oil must first pass around the cam bearing journal directly above it.

Actually, I have a picture of it, but decided not to post it.

Max you keep missing the point. **)**)**)**)**)**)**)**)**)**)**)**)

The oil pump and the relief valve are together This is the key to understanding what we have tried to explain to U.

The relief is on the BEGINNING of the circuit NOT on the end of the circuit. The more resistance (hose, filter, oil cooler, bearings,,,,,,,,) the more pressure will drop at each stage in circuit. The pump will reach its preset valve and that's it.......(unless you adjust or change the spring) (RESISTANCE is in the system otherwise you would not have oil pressure!!!!!!!!)
Do you think 100wt oil will have the same flow characteristics as 0wt oil if your oil pressure gage reads THE SAME value with both oils?????(remember your gauge is not reading the end of the circuit). Try blowing a milk shake through a straw then try the same with water which one will flow better?????????? The pressure will be the same at the BEGINNING of the straw, but the flow and velocity will be much higher at the end of the straw with water. WHY??? Because there is NO REGULATION on the COMPLETION of the circuit.

Many factors will affect the pressure. Why do you think so many people have pressure and volume issues when they add oil coolers??? The standard (PRESSURE) Melling Pump was not designed to over come that much resistance (with the factory spring) and does not have the volume when the oil is hot and thins out.

...my eyes glazed over and I almost drowned in my drink when I snoozed off several posts ago on this thread. :)

Some people are all flow and no go...:rolleyes:

Ahhhh, okay. Thank you Anthony. I had said all along the only way I could see that happening was if something was in the way of the oil flow.

To answer this question "Do you think 100wt oil will have the same flow characteristics as 0wt oil if your oil pressure gage reads THE SAME value with both oils?????"

Assuming a positive displacement pump with no relief lifting and infinite power source, YES YES YES flow will be the same with PD pump regardless of oil weight or oil circuit lenght. If oil circuits are identicle then it would be impossible for the pressures to be the same with both 0wt and 100wt.

I could get the pressure to read the same with a centrifugal pump but flowrate would be different
