Default Crank Sensor O-ring

It has apparently gone to hell and back. Looks like its the source of all the oil on the front of my oil pan and all the blow back as well. Replaced my belt today and got a so so look at the sensor, oil all over that area.

So where would I go about getting the correct sized o-ring? And what is the best way to get to it. Even with skinny hands and arms I could not reach it. Id like to be able to clean the area up as well.

I'm hoping this is the source of my oil leak.

How easy was the install?

You have to remove the front bumper and aluminum bar. Then slide the radiator forward. There is a single 10mm bolt holding it in. Replacing the O-ring is a waste of time. Just remove the sensor and clean everything super well. Make sure no oil remains on the block or the sensor. Apply some RTV around the O-ring and base of the sensor and reinstall.

cause RTV tends to breakdown and clog internal oil passages some can be used just people tend to over do it. I would recommend it for some people but for most DIY people they tend to think bigger / more is better and in that case I would rather see a leak than the alternative

RTV is fine as long as you place it on the sensor / O-ring accordingly. Using the correct RTV for oil based applications is alright.
