2005 Virago 250 oil leak

Post by Bilito » Tue Jan 22, 2019 9:08 am

HI I just changed the rear chain sprocket to a new gear two teeth less and while at it I removed the forward chain sprocket cover to clean all the stuff built up in there and after I took the bike for a test drive I suddenly had a dripping oil leak. I think it might be coming from the area in the front of the chain where the wires come out of the alternator side cover. That area was a real mess of built up grease and I may have damaged the seal there around the rubber grommet, I want to get some silicone to put around there to seal that area and I need to know what product to buy to do the job.
BTW It kept slowly dripping so I drained the oil and got it stopped.
What can I do???

Billto,
To really be sure the oil is coming from where you say it is. Here is a way to determine that. viewtopic.php?f=6&t=617

If it is indeed where you say, please attach a picture of where the oil is coming from. It will aid in determining what the best approach of action to take. I've never worked on a 250, so the picture would be most helpful. Others on the forum that have 250's may chime in. Could possibly be that all the gunk you cleaned off was keeping it from leaking.

Puts a lot of credence in the saying: "If it ain't broken, don't fix it." All kidding aside. A picture would be great to see what you are up against.

Make it 2 pictures. One close up, and the other farther away for reference.

Bilito,
Thanks for the pictures.
What is that that is all over the wiring and grommet? Is that the grease you spoke about? We need to be able to see the wiring grommet coming through the engine side cover case and where the oil may be coming to assess any damage. Can whatever is there be removed to see if there is any damage underneath it and what can be done to correct the problem. Right now we can't see we're blind. Even the service manual doesn't show this clearly that makes it all the more difficult.

If that is a silicone sealant spread over the wires, trust me, that won't seal the leak.

Let us know.

My gut feeling is that you will most likely need to replace your side engine cover gasket.
Around $8.00 for a Virago 250.

That mess of goo was an attempt by me to seal up the area around that grommet, I wanted to have a look at the bottom of the case, so I removed the side stand switch.
I could see about a 1/16 of an inch gap all along the bottom, that did not seem right and I decides what the heck I am gonna remove the case and have a look at the gasket.
I found damage in several place and a few tears,

New gasket is on order. Looking at all the damage I was surprised it was not leaking before. I think my super cleaning did what was left holding the oil back finally failed.
to my surprise the actual bottom of the case has no gasket and it probably explains that 1/16 inch gap I was looking at. The seal is above that part of the case.

Bilito,
Glad you found the problem.

I see what you are saying. The gasket doesn't cover that edge that would be at the bottom at all. I have no idea why Yamaha would have designed it that way.

When replacing the side cover screws do not over torque them. Check the service manual for torque values and screw tightening sequence.

Here is a method when replacing the side cover to assist in assembly and not damaging the new side engine cover gasket:

Good luck!
