Smile Oil Level Sensor leaking oil

my 2000 E320 has a small oil leak that seems to be comming from the oil level sensor. Any advice on how to replace the sensor would be appreciated.

IIRC it is very straight-forward. Remove engine part of belly pan, drain oil, drop lower oil pan, replace sensor, clean pan, reinstall. Renew the gasket if dried out (I probably would anyway). I can get you the torque spec tomorrow if someone doesn't get it to you first.

If you do not need extra qt of oil before oil change, any repair is not necessary.

AFAIK, both the top and bottom pans use sealant (Loctite). They do not use gaskets.

Maybe they do not want to spend the time to clean the pans so they like to sell you new ones. Just a possibility.

Thanks Lou. I couldn't remember if there were specific gaskets or the home-grown kind.

Hi Gregs210,

I tried to PM but couldn't, so have to hijack the thread a little bit, at least it's still about sensor.
I remember you mentioned about universal oxygen sensor and you were able to get all four for $180???

Would you please send me the link?
Thanks,

JeffreyP

Does this procedure also apply to a diesel. I am about to change the oil and I believe the sensor is leaking. Your advice regarding gasket replacement and torque spec will also be be appreciated. Thank you

Diesel sensor comes right out with no need for pan drop.
There are 2 orings. The smaller one for electric connector comes in the oil filter kit.

Please clarify, what do you mean by just comes out-----I did not see and nuts bolts or screws! Please note I have a 606.692 diesel engine

Additionally, a drawing I saw back only showed a gasket. When did they start including an oil level sensor o ring with the oil filter???

My filter came with two o rings,but they are for at the end of filter housing.
