Question about Cars & Trucks
I have a 80 corvette and the oil pressure gauge goes to 80 PSI when you turn the key on and stays there. I have replaced the gauge and confirmed the sending unit is working. Any ideas on where to find the problem?

chances are your sending unit is not bad. These dashes have had alot of problems with stepper motors failing in the instrument cluster. does it go to zero when key is off? is it erratic? changes where it sits when running and when off? These are all problems within the cluster itself. It is not cheap to take this to the dealer. THey will want to replace the cluster. these clusters can be repaired for half the cost if you know where to go. Not sure yet what the rules are on here but i can repair these for about 325 verses over 600 from dealer and then reproggramming costs! One other note. Chevy has a recall on these! call you local dealer and ask what the criteria is for the recall. You may be able to get it repaired for free if you meet the time frame and mileage requirements.

The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.
