i changed my oil filter about 2 weeks after putting new oil in because of loss of filter wrench but drivng to car wash the gauge was really high never seen it that high. So i wash it off and started it up to leave and the gauges was barely reading at all. could it just be the sending unit or a serious problem

 

A sending unit can go bad at any time, i would try changing it first. If you drove it home and didn`t have any problems then it should be ok. I did have the oil pump go bad on my 86 4Runner, and i was lucky enough to catch it before it did any damage.

 

Hot OP can look like it's not even reading... But a quick reference to THE OWNERS MANUAL and noticing if it's in the NORMAL ranges will, or should put yer fears to rest...

Anything not in normal is a cause for concern... But your light should come as well..

 

i used a manual oil pressure tester and at hot idle it was at 25 psi and at 3000 rpms it was about 70 psi i think that thats about right. what do you think probaly the oil pressure sending unit?

 

yes. either your sender unit is bad. or your gauge in the dash is bad. you have great pressure.

 

thanks every one.

 

damn..i run like..15 at idle..and about 50 at 3000rpms... =(

gonna change my oil..maybe switch back to 20w50
