    Posted: 10 hours 38 minutes ago at 8:52pm
On my WD45 today, I notices the oil pressure gauge is pegged to the high side at idle. I had the motor rebuilt last year. The oil does not look like it is over filled. Is it OK to have this high of oil pressure? If not, what would be my first step to address this issue?

I have the same issue with one of my 201 engines. I put a real gauge on there and it reads 90 lbs. I had to believe it reading a real gauge. Once the engine warms up the original gauge points straight up in the normal range (still about 45 lbs on the real gauge). I have now changed oil putting much thinner oil in it. The gauge still goes over to the far end on cold start up but takes shorter time to come back to the middle. A mystery to me.
Currently- WD,WC,3WF's,2 D14's B. Previously- I 600,TL745,200,FL9,FR12,H3,816 LBH. Earth has no sorrow that Heaven cannot heal!

Gauges fail. Verify and if bad then replace it.

Remove the filter base tube and clean it out by ramming a piece of wire down thru it and blowing air into it.
