Good evening:
I'll add my own question.
I've heard it said that raising the oil pressure in a vehicle can
actually decrease the oil flow to the bearings.
I can see where this might be true if one is using a pressurized system
which has only one exit. Decreasing the size of that exit to raise the
pressure would decrease the flow exiting the single tap.
When that concept is applied to our MG engines, I can't visualize how
raising the oil pressure could decrease the flow to the bearings. The
oil pressure is controlled by a dump valve which releases the excess oil
rather than trying to squirt it through the bearings. So, by raising
the oil pressure aren't you also increasing the amount of oil flow in
the system rather than letting it be dumped back into the sump?
