Front Belt Cover WET!

What would cause the front Belt guard to have mass amounts of oil inside and seeping all over the lower timing cover?

I pulled of the bottom Poly Pulley expecting the bottom seal to be worn under the pick up. Nothing.

There is a hole that goes through the casing, could this be where the oil is coming from? Crankcase ventilation issues? Rear seal failing or blockage?

I checked the manuals oil galley picture but cant see where this hole may be connected...

Weird...
Tomas

Clean it all REAL good. I use brake cleaner after a wash and dry....making sure the thing is clean as it was born. Then ride for 50 or so miles and look for the source.

An old master mechanic shared this trick with me and it has helped me to find some real odd leaks especially if air is blowing over the suspected area.
After washing and drying, spray the suspected area with antiperspirent and when it dries it will have a chaulky finish. That way you will see the origin of the leak easily and quickly.

I use baby powder. Like Bob said, clean the area REAL good then lightly dust. You'll see the leak very quick so don't make it a very long ride, or at least stop and check every so often.

Great tips!

What I'm also asking...is what is the purpose of the small hole that is at the bottom of the ignition plate? It appears most of the oil is coming from there. No oil on the shaft seal...

I suspect a crankcase breather issue....or the rear seal(S) have been improperly installed.

Cheers
Tomas
