Lets see if I can sort this out. This gets confusing so hang on.

Glen wrote the above because I posted the following question.
>John, your reply was regarding the 8-10 pound oil pressure at idle, what would
be the typical pressure at driving speeds (2000-3000 rpm)?
I asked the question because John had posted the following answer and I thought
he was responding to the idle oil pressure:
>Your pressure is about what is to be expected. The Rover motor does not make
high pressures.
John was replying because David Brown stated:
>I recently installed an oil gauge and discovered that my NEW (well, 17K miles
now) 4.6 block is only getting 8-10 psi at idle.
And he further stated:

Whew, did you figure that out? I did my research and found the *1961 Buick*
engine should be running about 33 lbs. at 2500 rpm (thanks to others who
responded and gave me similar numbers). But I did not find out any info on idle
pressure. However the brief time my engine was running it ran around the 30
mark at idle. Seems to me that 8-10 lbs at idle is low.
