Porsche 911 oil level sender replacement 911 (1965-89) – 930 turbo (1975-89) pelican parts diy maintenance article education level high school

If your oil level readings in your dashboard gauge are a little off, then it might be time to replace your oil level sender. Quite possibly the most dangerous part in the car, the oil tank level gauge is indeed mostly useless. Its measurements are only accurate when the car is warm and at idle. degree level education At all other times, the gauge will read artificially low or high values. Some of the times the sender or the gauge will stick, leading to more false readings. In general, the safe rule is to only check the oil using the dipstick located in the filler neck of the engine compartment. The oil should only be checked when the car is fully warmed up, and at idle.

The oil tank level sender is located on the outside surface of the tank, which is located in the rear right fender of the 911, behind the wheel. All 911s had their oil tanks in this location except for the 1972 911, which had it in the front.

The sender unit is held on with 5 small nuts that need to be removed. It’s a wise idea to clean the area of any dirt or debris that may have been flung up into this area from the tires. When you remove the sender, you don’t want any dirt falling into the tank.

The sender is an obscure shaped unit, and may require some wiggling in order to remove it from the tank. The new one should be installed in the same orientation as the old one. The sender can only mount on the holes one way, so you can’t really mess up the rotation. Make sure that you use a new gasket, and tighten the nuts snug.

If after installing the new unit, your gauge is still reading irregularly, you may need to replace the gauge. Unfortunately, the oil level gauge unit is not available as a separate unit: you have to purchase the entire gauge as a replacement. The old gauges simply pop out of the dashboard, and the new ones can be pushed back in after all of the electrical connections are reattached.

Comments: I have removed the wires of the Oil Sender Unit to clean around it and on replacing them can’t remember which one goes where. ie which to earth. One has rubber insulating on the actual terminal and the other does not. The wires seem to be the same colour due too age. I was cleaning as the gauge in the car was not showing an oil level but dropped a small fraction on turning the ignition off.

Comments: This is a follow-up post concerning the tightening torque for the nuts on the oil sender gauge. My oil tanks was leaking around the oil sender and I was going to change the gasket. All the screws were essentially thumb-tight. I tightened them a little more and now no leaking. Probably still change the gasket though. The OEM and Bentley service manuals do not state the tightening torgue for those nuts. Hoping to get some clear information on that. Performed extensive research and nothing turned up. Any help is appreciated on what the spec is supposed to be.

Comments: My 1985-911 Oil level gauge reads all the way in the red even when I have driven it for a few hours. I know it’s inaccurate as I just got the car from the shop and the car is filled with oil as directed by the shop book. secondary level education india What would you suggest???

Comments: I accidentally dropped the oil stick into the tank while checking the oil. When the mechanic removed it and poked and prodded and may have damaged the sensor. It was actually working very accurately before my incident with the dipstick. I need to know whether or not I need to remove the oil in the oil tank in order to install a new oil level sensor. Thank you very much for your help.

Comments: I bought the oil sender kit from Pelican, jacked up the 85 Targa, and found the non-functioning sender. What I didn’t see are the two wires that are supposed to be there!! Does Pelican sell a replacement wiring kit? What’s the terminus on the other end of the wire? In the engine space, or routed all the way to fuse box? Any suggestions for quick workarounds?

Comments: 1988 911 Targa and I’m replacing the cork oil level sensor gasket 91420189100 There is a notch on the outside edge of the gasket, but can’t find a corresponding notch on the metal cover to match. Does it matter where the notched area lines up when replacing?? Many thanks…..

Comments: I have 1973E with 47,000 miles and have owned car since l987. Have been doing some refurbishments on car including sending oil tank to Pacific Oil for refinishing. Have installed tank and filled with oil and run car and now have oil level indicator on dash pegging full as soon as switch is turned on. Checked circuit on power wire green with white around wire and ground and have proper voltage. Checked sending unit for resistance ohms and got reading of 1.4 K. My electrical guy says this is way to high for unit and probably indicates bad unit-guess I should have replaced it when tank was out. Never had any issues with oil system before. what does a level mean in education Do you think I need to replace unit?

Followup from the Pelican Staff: You should have 2 wires at the sending unit. One for the signal and one for the ground. I don’t know what you mean by the other end? Did you buy a replacement harness? If you did then you have to run the wires all the way to the gauge in the dashboard. – Nick at Pelican Parts

Followup from the Pelican Staff: You need to verify the gauge is getting electrical power. You should start by checking for voltage at the sending unit unplugged with a digital multimeter then load it with a grounded test light and see if the gauge moves. The most basic test is unplug the gauge and the needle should move all the way in one direction and then ground the sending unit wire and the needle should move all the way in the other direction. – Nick at Pelican Parts
