Pegasus: Engine Valve Cover Seal Leak

Post by PegasusRider »



I am haveing an engine valve seal leak motor oil. Its gotten to be a constant trickle. Only when running and I think only at higher rpm. I bought new seals off ebay. I have never done any like this before so any advice would be highly appreciated. In the pics you can see the leak from the bottom left bolt.

If it is just a rubber seal that is leaking, no problem. Simply remove the bolt, slide the old seal off, slide the new one on and reinstall the bolt. Just do not over torque the bolt when you reinstall it.

Oh wait, you will have to remove the engine guard first. That is a bit of a time consumer.

I bought some seals going to take oics of me doing the install. I will probably go ahead and replace all of them on each side while I have the bike apart.

Yes, replacing them all is a great idea. If one is leaking now for no reason other than age, the others are not far behind.

I changed them out and am Test driving today. It was really easy to change and so far in the day it has had no leaks. You need a 12mm socket for the engine frame, which I of course lost. 70 percent of the time it takes me to work on it is searching for the right tool.
