Oil Leak - Now with a damaged engine

[Alexio]

I think I have an oil leak... but I can't seen where it's coming from. It's basically been happening as long as I've owned the bike but when the engine reaches higher temperatures only then oil seems to start dripping down. It's incredibly slow but I don't know where it could be coming from.

Even while this is happening I only have to change the oil every 3000 miles or so.... so I'm wondering if it's just chain lube being thrown off the chain to eventually dribble down my center stand when this gunk is heated up?

And yes, I've tried cleaning this stuff up a couple times but it seems to come back it was a lot worse behind that metal casing hiding the sprocket. I'm probably just not being observant enough to figure this one out.

Is it possible that my engine is leaking from the gear change lever or the front sprocket that drives the chain? That's where it seemed to be the messiest.

[stirlinggaz]

looka like it might be coming from the gear shaft seal...
am i alone in thinking that bike needs a f*cking good clean? lol
cheers,

my money is on output shaft seal, not gear selector shaft.

lol, thanks guys. So most likely gear shaft seal or output shaft seal. It seems to be a slow leak but all the same, would I have to get someone to take apart the engine to find out which of these it is and replace the seal?

Personally I think it's the output shaft seal

dont need the engine apart. just screw a woodscrew into the old seal and yank it out with pliars.

need to take off the sprocket first though.

And obviously an oil change is going to happen if I like it or not at the same time? If I'm going to get my garage to order in a new seal for me I think I might as well just get them to replace it. I'm not feeling brave enough I don't think.

I had a similar situation on my CG when I first got it, it was due to the type of lube being put on getting flung off the front sprocket, once I changed to a waxy lube I never saw those patches of oil again.

However, yours does look like a bit more than I had even though its in the same place so I would get it checked out anyway, hope it works out well for you

[MaybeGuy]

it wont piss out oil if you take it out.
its just a seal to stop oil splashing out when the engines running.

a garage will charge about an hours labour for that, plus parts.

so about £50

or you can do it yourself for the price of a £3 seal.

Yeah, I don't think it's chain lube to be honest.... there was an epic amount of this gunk that I had to clean out next to the sprocket (behind the covering) which looked like it must have taken a few years to accumulate, that was hidden from view until I had to replace the chain.

£3 say you? Now that sounds worth the challenge of doing it myself


... or maybe get my friend who knows a little bit more than me to help out

Edit: wow you're right, they're pretty cheap things;

Another Edit: Damn it, I don't think that's my model... have to keep on searching...

you cant find everything online.

any bike shop will be able to order it in for you.

True, but some bike shops have been real awkward towards me ordering parts to fit myself, as if they think I'll screw it up for sure or something. I have a feeling it'll be another month before I get around to having this problem fixed anyway. Thanks for all the help If I bump this thread in a month from now it's because the problems still hasn't gone away

My front sprocket cover had an epic amount of gunk in it as well, so much so I cba cleaning it since it was hidden away anyway

Since it's a slow leak and you're taking your time with it anyway, might be worth changing to a waxier lube as an experiment and see if it stops (if you're not using one already)

[Alexio]

Hmm, can't remember which lube I last used to be honest.... was it that long ago? Yes it was... um, months and saying that I think I really need to adjust my chain too....

This is the problem when you only use your bike for mile long journeys through town for a few months, you forget to maintain your bike.

Ah, found it, this is what I last used:

Thought I'd just update this thread and share what actually happened to my oil seals. I'm kicking myself for not taking any pictures now, it looked fairly interesting.

Basically, about 3 months ago I was on my merry way along a dual carriage way going about 60 when a big polythene bag flies out in to my path. My reaction was not to swerve or anything because I didn't think of plastic bags as much of a threat.... but well, I was pretty wrong.

It caught my left foot peg, and then got pulled in to and mangled in my chain at this point I should have pulled over and attempted to remove as much of the plastic mess as possible but alas, I was late to get somewhere and did not.

So basically, this bag wrapped it's self 1000 times around my main drive shaft and was heated up to the point where it liquefied, and then further and more weirdly solidified inside the oil seal. It was hell to get all of it out.

The plus side is that the oil seal was successfully replaced.

The down side is that I went to london and back (160 miles ~) and at some point during the journey obviously ran a little low on oil as it slowly seeped out of my engine. Oh, and worse than that when I realised I topped it up with TOO much oil. Aaand I was late getting somewhere and may have pushed the bike to 70MPH.

Well there's the right amount of oil now but when my engine idles it makes this slight high pitched pinging noise, like metal striking metal on every rev. At least, I think it does, I'm sure it didn't sound like that before. When it starts to rev nearer ~3000 RPM it makes a horrible noise like ever such slight grating metal. Well I can either cry or admit the horrible truth that I've idiotically mostly likely damaged my piston / bore

If you keep the revs really low though the engine sounds pretty healthy still and you can still make gear changes and cruise as close to an engine idling speed as you dare..... but really I need to get this engine open I'm thinking. This CG is ending up costing me way more than I thought it would



Gah, I'm an idiot.

Sorry to hear about that I caught a plastic bag once too but it stuck to my exhaust instead, they are a right bugger arent they. I never knew it could do that

On the bright side, if there IS any damage to your engine it shouldn't cost too much to fix, a stupid guy I know decided not to use any oil at all for months in his cg and seized it properly, it was going again in a week.

Best of luck to you!

[Nipedley]

At least yours had a leak, his issues were down to the fact he ran it into the ground!

Apparently he had 90mph out of it as well

[Alexio]

Well, might as well update the thread. While my engine does still sound horrible to my ear, it seems to still have power and hit 70MPH. So I'm thinking that either there's a tiny problem with the piston and I'm busy wrecking it further (might as well at this point), or a different part of the engine is making the bad noise. I'll just keep on using it and it'll probably last me until I need my next bike.

But as far as oil leaks are concerned.... JUST SAY NO!
