Phantom Oil Leak?

[BoB3rt]

Was at oulton park couple of weeks ago,

Was the last lap of a session and gave it full throttle down the back straight under the bridge after the double apex,

the bike seem to loose power (like it was lacking petrol) but within a split second caught itself and power kicked back in.

However when getting back the paddock i had a oil spray across my Alternator casing, and then a dribble down the fairing under the case.

it was wet and cold so i loaded the bike on trailer and not had a chance to look until yesterday and cant find anything after cleaning it up.

I left the bike running untill at or just over standard temp and gave it a Good Rev! nothing appears to leak, i am hoping its the case gasket and not a head gasket or one in the engine block.

its a ZX6r '99 (G) am seeing if anyone can advise possiblities?

I have no idea what this hole is there for and cant find it in the haynes manual or a picture to see if it should be open???

thanks

Is there any airbox drains in the area?

Have you checked the oil levels correct? could be an oil overflow if you've overfilled it.

One things for sure, it ain't cured itself. the only way to find out whats wrong is to get it back up to the same temperature as when the problem first happened & then check it over.. at race speed oil is at it's most fluid & the engine it at maximum expansion & the best time to look for leaks,,,,, Bet it's a gasket

[BoB3rt]

nope there is no airbox drains around there, i have seen that happen on my friends R6 and thought it was oil

I did run it to above standard temp and gave it a good rev but nothing, to be honest its a bit risky taking it back the track to find a oil leak while razzing around

The oil level is fine smack in the middle of the min and max.

I think i will change the Alternator cover gasket never the less, its not a big job and i have a load of gasket paper and glue.

There shouldn't be oil in the alternator, should there? Maybe a seal has gone inside the alternator case.

[BoB3rt]

yep oil does go round the alternator.... just to be sure the alternator is the electromagnets that spin on the side of the engine usually in the left hand side casing??.....

I changed the gasket on my late gsxr midday at caldwell park, that gasket needed replacing.

true story, look heres a pic!

Ok so now been back the track and appear to have found where my oil is coming from... And it was one of the places i thought; that small hole anybody i ask has no clue what it is therefor.

However one person said it could be a Tell-tale hole - meaning it lets u know u have a broken seal inside, and its there as a breather hole and a warning.

Here are some pics:

 

 

 

 

As you can see it is weeping out of this random hole...but this weeping can become a dribble quickly and land on my back tyre. needs sorting!

would anyone have anymore info or ideas on this?

Thanks
