Oil level sensor leaking- replace the whole sensor?
 

I found the leak! I cleaned up my whole oil pan and found that the drip was coming from the oil level sensor. At least, I believe it is the oil level sensor. It is bolted on to the driver's side of the oil pan, the portion that sticks into the pan is a cylindrical shape. The leak was not coming from the o-ring that seals the aluminum body to the pan though, it was leaking from the small sensor that goes through the aluminum body. I tried to take the sensor out of the aluminum body but it wasn't coming easy and I didn't want to break it. My question is this; is there a way to remove the sensor from the body and get a new seal/sensor or do I have to buy the entire assembly with the sensor already in the aluminum body?

This is on my 87 300SDL with 167k miles. :sword2:

Anyone?

Ok, in that case, is anyone selling an oil level sensor for an 87 300SDL?
One that doesn't leak. Thanks! :rifle:

Mmm I could swear just the seal is available.

I just checked, it's about $1.50 for the pair... I'd order some other stuff so you're not paying $6-7 to ship ~$2 in stuff.

i have also seen the sensor leak not only through the o-ring, but also through the elactrical connection on the center, i would recommend the entire unit as opposed to just the o-ring

Hrm... I'm curious if this is where my oil leak could be at also. The light comes on at times for low oil... so I pull over paranoid and it's still full. :confused:

I bet it is, that's exactly what my light was doing. I ordered an entire assembly, $35 from my friends at S&G.

:D :D :D Hopefully it's that simple, I shall order this also here on the 14th.

Thanks for looking it up but if you went to Fastlane the small and large o-rings are not for the area from which the oil was leaking. The large o-ring seals it to the pan, the small o-ring is to seal the wire harness connection to the sensor. I think I'll tear it apart just to see what's in there, maybe I can even find the leak path. :rifle:

Do keep me posted in this thread or via PM please! :)

I won't know for quite a while if it fixed the oil light coming on, it's just one part on a very long list of things to do before it's back on the road. I should know if the leak is fixed on Monday, it better be or I'm getting my eyes checked. :eek:

Well as long as it eliminates the oil leak I'll be a happy camper.

I just tried to take the sensor out of the body but all I managed to do was break the sensor and I didn't even get it out. I guess buying a whole new assembly was the only option.

The new sensor unit didn't come with a large o-ring, go figure. :rifle: So I ordered one for $.75, good thing that didn't come with the assembly, wouldn't want to break the bank. I should know tomorrow if it's still leaking.

I can't believe it didn't come with the o-ring. That's pathetic.
