Oil Pressure gauge on my 94 4runner v6 drops down into the lower box on the indicator during idle. What should the actual oil pressure be at idle. Is it ok to drop into this lower box and if it is how far down into this bow would indicate a problem?
Thanks, Dale


Check the oil pressure sensor first. Maybe your pressure gauge raise after that.
