2.5 using oil

[pica]

This works for me to find leaks... no special glasses required

They sell dye that shows up with a special light and glasses that you put in oil to see where leaks are. My dad used it with good success on an old 93 night hawk. Takes a few oil chabges for the dye to get out the engine but no biggie.

I learn something new here almost every day. Thank you. I just bought some of this and now, maybe, I can see what's going on.

My buddy uses a dye like that for air conditioner leaks in cars. I think there's a special light to see it . (ultraviolet?)

Yea you need the uv light

I believe I may have found the cause which in a nutshell is the oil making it's way through the gear position indicator bolt holes.
I had previously replaced both o-rings, replaced them again with RTV goop around the flanges and it still oozed when riding. Then recently I removed the sensor, cleaned up the goop real well and installed new o-rings with a little lube. There was oil visible inside the bolt holes but I could not see all the way to the bottom. This time I pushed some goop inside those holes but did not apply any elsewhere. After I could feel a little of that excess o-ring lube making it's way out as I'm riding around but that's it. Nothing that smells or feels like oil. I'm pulling the bolts out one more time since I should have probably put more goop in there since there may be a minimal trace of oil on the outside and I also want to see what's going on in there.
That would also explain why the bolt heads always had a some oil around them.

i believe that you may be on to something
where the bolts are
does the hole go all the way thru. if so then you could silicone real good. if not then might be that some one had some sealer that put a crack when tighten down and a place for it to leak thru to the ot side.

The holes go in further than I can see though there was oil in them. Could be that if there is a hole at the bottom of one or both from the manufacturing process.

I normally take a small screwdriver to check the depth of the hole .
You never know about the drilling or tapping of the hole. A little to deep with the drill you may have a problem or a tap one turn to deep and you have a crack at the bottom
Sometimes i.have a leak in a transmission that is hard to tell where it is coming from so I overfull it about 3 quarts and let it set for 20 minutes and the leak will show up.
This is for test purposes only you have to remove the fluid b4 running.
If you try this i would Install the unit without bolts keeping in mind that if a hole is to far off it can pull the unit towards one side causing a leak on the o'rings. I have seen this b4 and have drilled the holes with the next size up drill at a very minimum those orings should last 3 years.

I'm riding 500mi out to Vegas this weekend and am leaving the gear position sensor alone for now to see how it holds up over distance/time. When I get back I'll make a decision about removing the bolts one at a time and pushing moore goop in the holes.
I understand what you said about the sensor being pulled to one side by uneven holes. Every time I have removed it so far I thread the bolts in by hand and then alternately tighten them 1/4 turn at a time to 10nm.

Would a little bit of plumbers teflon tape on the bolt threads stop the oil from seaping out ?
