Okay....So when I bought my valver it had a small oil leak on the right side of the head....looked like potential dizzy oil seal as the rocker gasket had recently been changed (a mechanics half ditched attempt of rectifying said leak!) So...removed dizzy, replaced both inner and outer oil seals...changed the oil and filter and hoped was fixed. Still oil on the bell housing and my driveway! Now, underneath the dizzy is a black hose (about 25-30mm) with what seems to be some form of meshed breather

not too sure what this is or if indeed this could leak oil.
Suppose my question is...has anybody else experienced such leak or could anybody cast any light on potentially where it may be coming from?
My only alternative seems to be a deep clean followed by UV dye in the oil
Cheers all
