    Default Oil level sensor leak

    So my BII has a leak at the oil level sensor. They don't make the gaskets anymore as far as I can tell. Anyone try RTV in this sort of instance? I really don't need the sensor, I wonder if I could find a plug for it?

    I would think a good chemically resistant rtv would work. Either as a gasket, or if oosdible around it where it goes into the block. Guessing on application, just saying that because I s3aled a leaking, actually draing, yoke seal on my tj np231 output. Even though it was only a finger bead around the area, it worked for years.

    Don't they have kits of make-a-gasket where you can cut your own? https://www.amazon.com/dp/B000BWE3VO..._rc1sDb029N3W2

    I don't - I think I first saw them on Road Kill (that may or may not be actually an endorsement that they work well in the long run)

    I have not used that kind before, but have used the cork style sheets and just cut out what I needed with good results.
    However like you wrote, "gasket maker" RTV made to work with oil and the temperature it would handle would work too, if applied properly ;)
    Hope this helps and wish you good luck either way.
    Traction, articulation, and gearing make a good off-road rig. Just a big lift, wide mud tires, and a winch simply do not.

    What does it look like? Flange? Pipe thread? I'm guessing it's a flange like a thermostat housing? If so, RTV should work fine on clean, smooth surfaces with no gouges.

    I agree; the "if applied properly" is key. I'd try red RTV, thin bead, let it "skin" (about 15-20 minutes), install snug, wait another 5 minutes, then torque to spec. This is how I install my diff covers and haven't had a leak yet.
