HATCHY Posted December 22, 2006 Share Posted December 22, 2006 Just a small question! Do you really even need an oil pressure guage?. But it sounds like electrical problem to me. I had that problem on my Mr2. But all I had to do was unplug it and plug it back in.. It was wierd.. Link to comment Share on other sites More sharing options...

I had one on my 1988 it would peg at 80 psi one a winter day when it was cold. the real danger to pegging the gauge is bending the needle on the gauge. If its an electrical gauge this wont happen, on a mechanical gauge it might. I wouldnt worry about it. What you want to worry about is how low it is. Once the oil warms up you should have normal readings. And a gauge is better then a light anyday, but using both with a T is even better. nipper Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 22, 2006 Share Posted December 22, 2006 Yeah - fairly normal for a cold engine. Especially this time of year. I advocate working guages be installed on ALL EA series soobs. The lack of a guage on my digi-dash 84 wagon caused the destruction of it's engine at a mere 165k. If it had a guage at the time, I would have known it needed a new oil pump. GD Link to comment Share on other sites More sharing options...
