Oil in airbox

[angus7tb4]

Hi,

I have a problem because I have oil in my airbox but it doesn't look creamy white oil, it's really only oil. 




I cleared out the little breather part on the bottom of the airbox wich holds the evaporation back.
I didn't put too much oil. 


I don't reach to find where it come from. 
What I don't understand is that the crankcase breather pipe is dry, there's no oil inside. 
And for the 4 pipes at the end of the airbox there's equally no oil inside. It's just a little bit fat/greasy but not wet. 

On compression test, it's 8cm2/kg instead of 12 so it signifies a really used engine normally?
However, with only a few lack of power, the engine run's well (96000kms), in 3000 kilometers it only used just above the half of the oil window and yet I'm not an angel with my right hand.   
Normally with this conditions it would be more? 
Any idea?

Having cleaned it out I'd keep running it & check again - might have been a one-off issue.

Re the compression test - did you add a few drops of oil in the plug hole before testing? Else the results might be wrong.

I wanted to do that but the garage owner's who did it was to busy. And to him, the moteur was dead and it would be useless to lost time do that.
He asked me 60€ just for 15mns.... so I'll do it next time myself!

If the level compression is higher with oil in hole it signifies that piston rings are dead?

Nope you will hear a scraping ring(s) probably a bit of an overfill escaping via the breather when hot.

ive a 600n its a bastard for leaking oil from air box
its a big prob with the 600 ive cleaned breather pipes clutch cover breather had water and white snot in it rest were ok.
after the clean went for a burn its done wonders just a small drip
so its going to be on going just have to clean pipes regular
