I had a similar experience to 37Flat with oil pressure on my '54 Ford NAA tractor. If I remember correctly, (it was several years ago) I had just finished changing the oil and filter. Upon re-starting, the oil pressure gauge went full-scale in a few seconds and stuck there. I didn't resolve the issue, but continued to use the tractor on a limited basis for several years now. It does burn considerable oil, which might be attributable to too much oil pressure? I'm sure it needs an overhaul, but I wonder about the oil pump relief valve. Does anyone think excessive oil usage can be attributed to too much oil pressure?

I have never serviced the oil pump, and the engine has only been apart once, in the 1972 time frame, to replace a stuck and damaged valve. I also renewed the rings and rod bearings. It ran fine for years, using it mostly for gardening and bush-hogging several acres. I need to rebuild it, but have a later tractor that I use mostly, a '76 Ford 5000 diesel.
