Oil leak from under ignition cover

I tried the search function, but it kept coming up as "fatal error"! My '82 1100EZ has a small oil leak coming from under the ignition cover(right side)...my r/s boot has oil on it after a long ride. Is this a common place for an oil leak? Crank seal? I haven't even looked in the shop manual yet...figured I'd get a faster response here (in other words i'm kind of being lazy):D. TIA
 
Not common. Crank seal would be my guess.
 
Yep, likely the crank seal. BTW, it's been said that the seal should be installed with the metal side out (not as shown in my service manual anyway).

While I'm inclined to agree with everyone regarding the possibility of it being your crank seal, I'd suggest investigating further before going with it. Myself and many others have had small weeps around lower case bolts, or an oil pan gasket weep that when blown around by wind looks like it's coming from many different places. I'd suggest a good scrub down, wash the motor up, spread a lil talcum powder/diaper powder whatever (do everyone a favor and use some cocaine you lifted off the local dealer after pistol whipping him :p just don't breathe it in ;) ) and let the motor run to see if you've got other minor leaks if you find that the seal isnt obviously leaking.
 
It's definitely leaking from behind the ignition plate and coming out of the little weep hole in the bottom of the small ign. cover. The crank seal doesn't have a locating rib on the OD like some bikes do, does it? (cases must be split to change out the ribbed style crank seals). This looks to me like removing the ignition plate and seal should be directly behind it, no? Any tips/tricks/additional info would be helpful. This is pretty much the only oil leak on the bike (9100 miles:eek:)

You do not have to split the cases.
Loosen the first couple of case bolts around the seal. Freeze the new seal.
Take out the old seal with a wood screw or similar.
With the cold seal put a little grease around it and use a large socket or PC pipe and pound it in. Get two in case you go in crooked the first time.
 
To install the new seal, thread a long-ish 8mm bolt into the crank, and use a short piece of pipe or a large socket, along with a coupla washers and nuts, to press the seal in.

No need to pound it in (egads, how very uncivilized...) when you have a handy threaded hole to use.

FWIW, the manual specifies using a thin coat of case sealer on the OD of the new seal.

Also, yes, cranl seals do look like they install "backwards" with the metal side out. There's a tiny arrow on the seal showing the direction of rotation.

Guess how I learned this... :rolleyes:

You know Brian I did do it this way the last time. I do believe I did a search and found a post by you.
Sorry for the caveman method. :eek:
 
When you guys get our new buddy all squared away, tell me why my left boot is soaked with oil from a 10 mile ride on the street...man, am I getting good at these thread hijacks...:eek:

I too have an oil leak, but where is your leak located exactly?

I too have an oil leak, but where is your leak located exactly?

Hi all!
I saw the first post that this leak was near the ignition cover.

I have an 82 gs850g and and oil leak that I have seems to be coming from the front part of the bike and down the front levels of the cylinder head.

When i took off the gas tank it revealed a slash in the breather hose. i patched it up until i could get a replacement. Cleaned up the spray on top of the carb covers and down near the spark plugs. I did this when i did an oil change.
When the breather hose arrived i went back, but the leak wasn't coming from the hose, though it was new oil coming out for sure somewhere from just around the spark plugs, dripping on the left side and down the cylinder head.

Is that too where the ignition cover is and could my leak also be a crank seal?
it's not a very big leak, but it is persistent and could be fouling my #3 spark plug.

I'm female doing the work with fellow gearhead friends.
Thanks bunches!
 
The ignition cover is on the right-hand side of the bike (as you sit on it). On the left hand side is the stator cover. Scrub it really well and see if you can get it clean, then put some powder on it to really nail it down. When you're riding the wind can whip oil around so there's no telling where it's coming from. It's not unusual to have leaks around the valve cover, particularly around the half-moons under the cam end covers (the shiny round covers).

You could also post a pic... And introduce yourself in the GS Owners forum!

Chef Bill is a great guy, very helpful and all, but I recommend against loosening any crankcase screws unless absolutely necessary. Doing so can introduce an oil leak from a different place. Not worth the risk unless you can't get the seal in any other way.
