The factory sez 73 psi is max. Smartly I execute a 180 turn and retrace the ten miles to the airport. While taxiing back to the shadeport I goof with the throttle and see that the oil pressure rises and falls with the RPM, but by the time it gets to 4,000 RPM we're showing 100 psi. Inspection shows no leakage. I'm hoping it's something cheap, easy and on top... Any help troubleshooting this would be most appreciated... Thanks in advance.

David Joyce + 914, which had similar issue a few years back.

Vibration usually kills them over time. Not recommending you do this, but I moved my sender from the engine block to the firewall and have a length of pressure hose from the block to the sender. So far, no problems. Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop (90 hrs).
