High-sided, possible oil leak?
06/10/11 10:08 PM

I high-sided my 14 2 weeks ago. Did some looking and found a lot of fresh oil on the engine where the headers are connected.

This picture is taken right above the two middle headers. The circled area is a bead of oil preparing itself to drip onto my header. Is something cracked or this a result of the crash and oil getting to places it normally doesn't go and will burn off after some ride time?

It seems like the oil only really started to bead down onto the headers after I put on the rear stand and caused the bike to lean forward from the elevated rear.

Did the engine contact anything when it hit?Take a good look along the valve cover gasket.Right to left or whatever.Along the front side.I'm guessing you did not crack anything.How are the header pipes?Loose?Any damage to the underside of the exhaust?Like maybe it got smacked right there?I can't really tell what I'm looking at in that pic...I mean...I see the header pipe,yes,but right above it....IDK what that is?(without looking at mine)Is that the block right there?It looks as if it's seeping DOWN to the header pipe...which means...it probably is coming from the valve cover gasket there along the front.If it wasn't leaking BEFORE the highside,then it probably trapped some oil up under the gasket skirt inside.Now,it's making it's way OUT.That's my guess there.

If the exhaust did not get "pushed up" by hitting something...it's unlikely the motor moved at all.Which to me means...NO CRACKS or damage...just oil at the valve cover.Which WILL burn off.Wipe the valve cover gasket area on the sides and front really good.Start your bike.Check it after she runs a bit...maybe leave her on the rear stand.Just stay out of gear.

Crashes can do strange things. My Busa had a puddle of oil on the top of the transmission case after I got it home from the crash at the track, no idea where it came from.
Wipe it off real well and see if it comes back. If it does, inspect the area to find exactly where it's coming from, then look for any damage.

You start looking the bike over really close after an incident. Maybe you find "new problems" that were there for some time.

Same symptoms as my never crashed 08 but my leek is much slower. It burns away during daily use. I never see it unless the bike sits for a couple months. Never had any run off onto floor but it ran all the way down to the oil drain plug in winter storage last season.. I plan to change to a new valve cover gasket soon and i expect that to stop the oil loss.

You might try to put washers under the bolt heads and tighten down the valve cover to speced torque. I would start to think you have a cracked motor.

Thanks for the input everyone. I'll clean the area up and once I get my replacement upper fairing stay so I can mount my headlights I will be able to ride again and burn off any current oil and see if new oil shows face.

I don't think the headers ever hit the ground. The bike slammed on the left side but didn't even scratch my radiator. The bike continued running for a few seconds after it was on it side so I would imagine that caused a lot of fluid to go places it shouldn't. The bike fires up every time no issues and idles normal. Guess I'm just being slightly paranoid since I've never crashed before and I view my motorcycle as my pride and joy.

Once I'm able to ride again I'll post back with my findings. Thanks again.

That is a leak not a seep.

Seep: Thousands of miles, it fans out at the center. The grit forms a layer; can coat over it each time out. That absorbs the oil. Cakes it on. Never leaves that round pool.

Leak: A leak however, drops to the ground, on the pipe. The loss of oil is heavy at the window marks.

A. A moved gasket, meaning, look higher than the exhaust flange area that is 'circled.'
B. I can only think of two things that a tumble could do:
1. Move the gasket and break a seal.
2. Crack a part that starts the leak taking a high side stumble.

I think what I'm seeing there is.....the exhaust flange and the mount bolt(where the half moon oil mark is.If that's what it is...then....I THINK the upset allowed oil to enter the valve assembly,oil got forced out at the exhaust,and there's your half moon oil spot.It's being(or WAS being)pushed out through the bolt hole cutout on the flange,and the header seal itself.Did the OP look "behind" that flange,where oil could easily pool up on that flanged lip?The ring?.The rest of the oil on the engine there is blowback from the exhaust header(flange ring).Probably got some serious oil in there somewhere.The valve cover is most likely PERFECTO!Doesn't the oil try to come up through the plugs if she's overfilled?That engine area right there.If it couldn't get past the plugs,then it probably got pushed into the header gasket seal.IDK.I know it wasn't overfilled...but....an upset could mimic an overfilled situation,yes?That valve area...that could get extra oil in there,right,from being tipped over?I think his motor's fine.I don't think there's a leak at all....just some oil got where it's not supposed to.


Here's a thought.How about looking at the drain container down at the shift lever.Any oil in there?

killing me Larry!"

NO! Plain and simple. You have to see a bent/cracked guide to be pushing out the exhaust. He said it burns on the outside of the pipe, not start up?

If it was star up, then blows it goes all day long till you turn the key off. Like saying you turn on a faucet and lie to yourself it is not on. Only when I'm home is it off. Only when I leave I can't hear the trees fall in the forest.

Gotta brake clean and air blow that dry. Gotta pop a fresh one, sit and wait for it to happen every 5 minutes and stop. OR; don't drink, take it for a ride and hurry back, shut it off. Now, sit and watch for the leak after about 5-10 minutes of cool time. This is still an air cooled bike sort of watch the water temp.

It will show up if that is a leak-LEAK!

Thought you'd like that little "synopsis".Fuc^...I don't know.How bout the "mimicking" part...any possible weight in that?

So now you've got im watchin the temp bar....presumably...having the key "on".You aint tryin to sell those Shorai's by any chance are ya there Hubster?
