ettev Posted July 23, 2008 Share Posted July 23, 2008 Symptoms: 1985 Brat - Oil pressure dash guage reads near 75 psi all the time, hot, cold, idling, normal driving, even when the engine is shut off. Measures taken so far yielding no changes: completely rebuilt the oil pump (new o-rings, shimmed the spring, new mounting gasket, etc.) Installed new sending unit. Most likely culprit is....................._______________? If its the wire lead wear are they prone to have problems? Link to comment Share on other sites More sharing options...
nipper Posted July 23, 2008 Share Posted July 23, 2008 Sending unit. Disconnect the wire and see if it goes to zero. nipper Link to comment Share on other sites More sharing options...

Sending unit is brand new NAPA. Next place to look? Link to comment Share on other sites More sharing options...

Loyale 2.7 Turbo Posted July 23, 2008 Share Posted July 23, 2008 ...Or the Gauge`s Wires, it could be a Wire Grounding... Except if the Gauge doesn`t Low even with Battery Disconnected... in that Case, Just the Gauge itself. Good Luck! Link to comment Share on other sites More sharing options...

Cougar Posted July 24, 2008 Share Posted July 24, 2008 Since you state that the gauge shows a reading even with the engine of then the gauge itself is stuck and it needs to be replaced. Link to comment Share on other sites More sharing options...
