needle bearing in oil pan

I just found a needle bearing in my oil pan of 95 R100gspd. I removed it to change gasket and while cleaning pan found what looks like a needle bearing and some plastice blue looking material the blue material was half circle what looks like would be a2 inch diameter ring. Any ideas of what it may be from and what to do? Did not have any problem with bike before i started.

pics? approximate dimensions of needle bearing?

sounds like valve rocker bearing R&R time, except for the blue stuff

Maybe look at your rocker arms for broken rocker shaft spacers and missing needles...? The bearing cages have been know to wear thru or crack on the end.

The needle bearing is most likely from a rocker arm bearing. Pull the rocker arms and replace the broken bearing. Sometimes the broken bearing muffs the shaft. With a rocker and shaft in your hand, rotate the other rocker arms on the shafts and feel for notched bearings somewhat like steering heads get only different. If they are notched, replace them. I try to wait and replace them all during a valve job but . . . . I have never noticed a cage that has worn through. They just crack for some reason. They will crack with too much rocker arm end play and they will crack with perfect rocker arm end play.

I suspect the other stuff is a gob of blue RTV that was smeared around the filter cover gasket and then it fell inside of the engine? That's about all I can imagine right now. If so, poor goobered engine.

Rocker needle bearing. The proper fix is to replace all 8 bearings in all 4 rocker shafts. Some will try to fix just the bad ones and next year the next ones and then the last ones and, you get the idea?

Those rockers are really different than what someone like I have. But they have the same needle bearings, don't they?

Is the piece of plastic a hard piece of plastic or more like rubber?

You need a photo share site like smugmug or flicker. You could also email me the pic and I'll post it for you. hardwaregrrl@yahoo.com

Oh no. That sounds like the front main bearing locating pin. Your front main bearing could move and block the oil passages that oil the rocker arms. Sometimes they will run a long time or maybe forever without the pin and sometimes they don't.

If the needle bearings aren't notched per my advise, I don't think you need to replace all of them. I don't think they fail like disston described. In my experience, they are like airhead lifters. Some flake and others don't. It's the same with rocker arm needle bearings IMO. Some cages break and others don't. They won't all eventually break but they all will eventually get notched.

I am still thinking the blue stuff is silicon that was goobered on the filter cover gasket and squeezed out on the inside and then fell into the pan?

Or blue loctite that got pushed through by a fastener

Gawd, first it was the oil filter getting put in wrong, then it was final drive splines, then clutch splines, incorrect wheel bearing pre-load....

I'm losing track of all the things that are supposed to go wrong with these things.
So far, (knock on wood), I haven't had a problem with any of them.
With well over 100,000 miles on mine, should I be looking into this now?

Ouch. Agreed.

Vech (Benchmark) is up-state near Starkville and I'm not up that much on Ms wrenches.

I''ve thought about tapping the main bearing pin hole and substituting a loctited setscrew for that pesky pin. I've got a timing chain replacement coming up later this Spring and I ma considering going a little further and pulling the front main bearing cap for a peek at the pin.

Please regard the advice from supershaft more accurate than that from myself. He does this stuff a lot more than I. And I'm just anal about replacing everything, all the time.

A two inch diameter thread of Locktight? And dry Locktight is not rubbery. Really sounds like Blue RTV. The picture will tell.
