Re: Re: First Technical Question - Islero Oil Press Gauge

Hi Udo, Welcome to the new (very new) list. I agree with Fred. The sending unit is not all that reliable. I have an unusual problem with my readings when the engine gets to normal operating temperatures. The maximum pressure indicated is about 7 atmospheres. I just rebuilt my engine less than two years ago with new everything, so I know there is nothing wrong with the engine. The usual problem is the sending unit. But in your case, it wouldn"t hurt to also check the pressure relief valve located in the oil filter base. I can"t image it causing the symptoms you mentioned but I would look at it anyway. Check everything with a mechanical gauge. That will probably identify the problem.
