oil level sensor issue

Hey guys ,
I have a crazy question The low oil level sensor on 82 XJ Max leaks after its been ridden even for a little.....5-10 min. The strange thing is no leaks when it's cool and sitting on stand ...not even a little.
I recently rebuilt the top end and replaced O-ring on sensor.

Is it possible that flange bolts need some sealant or the epoxy or what ever the sealant is that surrounds the wires protruding from the bottom has seen its life cycle ? I do have a manual and regular read posts on the forum.
Thanks in advance for any advice or questions.

It very well could be leaking through the sensor itself. One solution would be to remove it, carefully and thoroughly flush it out with contact cleaner and then apply a CA-type ("superglue") adhesive to the wires where they come through the plastic to seal them.

However, I'm not 100% sure how effective that would be long-term; you could also just "pot" the bottom of it with high-temp RTV which although not as elegant would probably hold up better. I've used this method myself in similar applications (but not specifically on a Yammie oil level sensor.) Again, getting the part as clean and oil-free as possible prior to application is the key to success.

If it's leaking around the sensor, I'd slather it with RTV and re-fit.

I would simply recommend replacement but since it works and is an outlandishly expensive part I'd try to seal it too.

Suggestion: get everything uber-clean and do the "talcum powder trick" to isolate the precise source of the leak so you know which battle to fight.

 

Thanks Fitz
I will be using HiTemp RTV silicone method, cuz it's a @!$' it is to get to each time.
My hats off to all the insight that you guys give us shade tree mechanics.
