Can't find this part or it's name... leaking oil

[hoehn.marcus]

I can't find the exploded diagram with this part. I am leakig oil bad, and I'm pretty confident that it is coming from this guy here... Is there a gasket that goes in it that I could replace?

If you are talking the tan thing that's your oil pressure sensor switch.

What bike are we talking about? Put it in your signature

Some guys with that bike will be able to help.
You can go to an online parts fiche and find out yourwelf.

Sorry, I have a 1980 GS850. I have looked at a couple sites with the fiche but I cannot find this part. Not just the tan plastic plug, but the entire metal part that it screws into and both bolts...

[JEEPRUSTY]

Horrid looking fiche. I have not seen one this bad. It looks like the O-Rings are there but are they available?

Yep for the base, 56 for the switch

[cowboyup3371]

Looking at your picture again, are you positive it's leaking from there? Looks more like residue from your valve cover or even your cam chain tensioner gaskets.

and part 53 is a O ring...

[hoehn.marcus]

Yes! I can't believe I was missing it! It is coming from either there or like cowboyup said, it may be the tensioner. Which is more likely? I bought this thing for 400 and it is running great, but I drove 60 miles the other day and lost about 2.5 quarts of oil, so it's a pretty significant leak... Any suggestions or pointers would be appreciated.

[JEEPRUSTY]

If you lost that much oil then suspect the o-ring and not the tensioner.

[cowboyup3371]

Whatever you do, clean everything up first. Spray some foot powder around the area you think is leaking and ride it for a bit. Then verify where it's coming from. This way you aren't just throwing money into areas you don't need to.

I like your style. I initially thought it was the head gasket, but I drove it a little today and it started and I could tell, but not precisely. I coul narrow it downto he tensioner or the pressure sensor.

I really like the footpowder idea.

[hoehn.marcus]

Ok, so I am quite confident that it is coming from the oil pressure sensor assembly. I pulled the tan plastic plug (sensor) and cleaned the o ring and even dabbed a little bit of gasket sealer on it and tightened it back up. It is not the sensor itself... would it be the metal assembly?
