oil over the place

[moanthebairns]

Up at knockhill today, I suspected a little oil leak from the 675 before, but after cleaning it up it looked to be fine, so a new oil and filter on Friday and off to track. I thought it was just from me spilling some when filling it that had got under the casings, it never leaked on the road.

I felt the rear almost go a few times, just all of a sudden but kept it up right, thinking "must have fked that corner up". Weird as hell feeling, no warning.

Get off for the final session, my boot is soaking, so is my right hand side of the bike.

Get it home and find this







I lost half a litre of oil, very lucky.

Is it possible with the damage to the casing that it has cause a hairline crack/pin hole and the oil is pissing out on the track under pressure. Its hard to tell where its coming from but I suspect its that casing.

Its oossible, yea. Its also possible the cover is warped so that oil is leaking past the seam (if you get me). Degrease the whole area and clean it up, then run the engine and throw lots of talc over it - you should be able to see where the oil is seeping from.

Are there any breathe pipes there that might have ruptured?

Not that im aware of but don't hold me to it.

I heard about talc, what will it show, just it soaking any oil?

[moanthebairns]

can say with certainty, that casing is £70

ill clean it up tomorrow and get the baby power on it, if it is then ill just but a new casing, if its not then im fked.

[moanthebairns]

It could just be a gasket, ill degrease it tomorrow and cover in the baby powder I bought.

I don't care about money on this one, I just want it sorted and sorted right, its a track only bike now and I don't want to take the chance.

I reckon the casing has just loosened the gasket after the knock that it's had, so that'd be my first thought to replace, although I'd do the casing too, as I like to play it safe.

There's a,so the chance that you haven't tightened the new filter enough. I've done that once. Never again.

Bear in mind I am a mechanical a muppet though.

filter was tightened with a torque wrench, its obviously been weeping for a while as I had a small amount at my casing the last time.

Maybe the pictures don't show it very well but they don't look lagged in oil at all. The inside of bellypans always look like that after a while, they just collect road grime.

Its just the pictures, its very hard to show up.

My boot was covered in it, the casings soaked, your never going to see it particularly well on a photo.

I took a fairing bolt off and it looked like it had been copper slipped it was that bad.

ITS fkED, new one ordered £80 odd including gasket.

It came apparent that when up to temperature and on revs that it was dripping quite badly, obscured by the casing protector. The off at Croft must have finished it off.

On a positive note, I drained the oil and it is spotless, not a lick of dirt came out. Mind you it gets changed every two trackdays

Then it's not doing its job! Or you're a pussy with the throttle

its turned black from red, but I meant no big fk off bits of metal. To be fair it has only done one track day.

The other basin I use for regular oil changes sits in the garage, its full of dirt, grit, sand and dead spiders.

I know your meant to check your oil to see for swarf, but when your basin is full of st its kinda difficult and I cant be arsed cleaning it.

The skank over the road never tried to snort the tarmac did she?

No but I heard her shout to her pal who was half way up the street. My God I thought I sounded common, I thought it was Mary Doll from Rab C when I heard her talk.

Is the baby powder a real thing or did you just like the idea how him making a of himself?

Id heard it used before on the 675 forum. It does work well.

I doubt its anywhere near as good as the proper stuff which cost about a quid a use.

I want you think about that when you're sweeping up baby powder.

Whats the proper stuff, the dye that you need ultra violet light to see?

[moanthebairns]

Baby Powder £1.50 from Asda.
Bought at 9pm for use the next day.

No brainer

(Since this great thread seems to have finished its usefulness I'll chance an Asda question)

I went there about 4 years back, 5 maybe and they had mobil 1 at 16 quid per 4 litres. Never been back after clearing them out, but what amazed me was the amount of flange in there! Christ I've never seen anything like it.

Presumably you picked up your talc from near the condoms and I imagine there were even more around there than the engine oil?

being a piping designer when you said flange I thought of these first.

it wasn't till I read your second paragraph that it clicked.

That crack looked weldable to me

Why is it when I spend money, people say, "by eck id have fixed that"

yet when I don't want to spend much money people call me a tight arse.

The thing is fked, buy a new one.

wtf is £70 you cant even get a hooker and a gram of ching for that. st loads of baby powder though

[moanthebairns]

You'll be glad to know its all sorted now.

One mistake was forgetting I had the old sump plug washer still in then filling it with 3 litres of oil. fk. Still I swapped it over in the blink of an eye.

Took an hour to clean up the old gasket that had melted onto the face of the casing.

job done. All back together for its last day out this year.

Do people really care about this?

I've had the same sump plug washer for about 70k, it's never leaked yet even with 4k oil changes. I only changed it when I did to see what difference it made, which was nowt.

I could have used it again, the compression on it was fk all.
