760 GLE/1987/My oil light is on for some reason.

I recently took my car to the car wash, and since my car has a couple leaks i figured i'd open the hood and spray some engine degreaser in it and then wash it clean with water to get rid of all the build up of the 22 years the car has been alive. So I did! I drove home, and everything was fine. Then I got back in my car and my oil light is on and my car feels like it wants to die (rpms would jump up and then decrease. repeat). The lack of power went away after 2 days but my oil light is still on and I have put oil in it and checked if it is at the correct level and it is. Anyone have any idea why my oil light is still on?

check all your wires under the hood... that engine degreaser is a PITA on old wires, sometimes eating right thru them. Make sure you have no bare spots, and check connections, if all else fails, check your sending unit. you may have fried it.

Dang wish I would of known this, considering the previous owner of this car obviously didn't take this car to the best garage when it had problems... most of wires are all taped up, have bare spots, and all in all just look like crap. I would like to get this fixed but I am scared it will cost a fortune

I am just gonna say the worst and go with that I fried the sending unit. Because even disconnecting the battery and reconnecting which i thought would reset it did it for about a day and then the light just turned back on.

Its probably not the best way but you could redo the wiring yourself... It WILL take a while, maybe a day or two, but at least you will know it will work. Just get some of those heat shrink butt splices and a LOT of wire ( different colors for doing it right ) and some of that wire loom plastic stuff that is split and you can put the wires in to protect them. Then undo all the tape and plastic from your wiring up to where they go in the car, and one wire at a time, Cut on end, butt splice a new wire, and follow it to the other end and reconnect the new wire. The plugs, and connectors are extremely hard to find, but at least there will be no more bare spots, and it will save you a few hundred bucks or so. then make sure you use electrical tape after each butt splice has been heat shrunk to keep moisture out. Pretty soon, you will have a whole new wiring harness and you will only be out maybe 60 bucks.

Again, not the best way, but at least you know you will have gotten everything under the hood.

JUST be careful! those connections are OLD and Brittle.

Thank you for such a speedy response. LUCKILY! my plug wires look almost new

thank god... because I've priced those and they are not cheap. Its just basically everything else is crappy looking, mostly to my fuel injectors...

But yet again, thank you. I will probably most likely start this project when pay day comes
