I'll let everyone know the result of my oil eperiment.

I've spent an awful lot of time and money on this manifold pressure problem. I'm hoping higher oil pressue is the answer, at last. Having the manifold pressue surge by a couple of inches whenever I try to reduce RPM below 2500 is simply unacceptable. There is something wrong somewhere,and it isn't induction leaks, in my case.

It might seem picky to want to cruise at 2350 instead of 2500. But 2350 reduces the noise level a lot. And the power setting chart in the POH indicates that the T337G should be able to cruise at 20,000 feet at 2300 RPM. I'd settle for 2350 at 180.
