My new 6 has a pipercross crankcase breather which seems to be smoking! Shock

Theres a pic below, as you can see the filter looks oily and seems to be letting off very light white smoke with engine running. I appreciate the oil may be burning off it, but any other suggestions? Is this common?

Piccy Clicky

The underside of the bonnet and some other areas appear to be coated in a mist of oil, but I'm not sure if this could be from when the previous engine went bang?

I have an oil catch tank with that sort of breather on the top and it smokes a little from time to time and lets off a bit of a smell, nothing to worry about mate its just breathing off all the shit that would otherwise be being recycled through your inlet manifold and valves etc coating all the sensors and everything in shite.
Mine does it quite a bit because the piston rings are begining to get past it a bit and let a bit to much compression into the crankcase but expected after nearly 125k of thrashing Wink

i'd sack it off and return it to standard, there's meant to be a valve there.

I think I will. There's a fair bit of smoke coming from
the breather. I really hope it's nothing to worry about. There's also a noise coming from what seems to be just below and behind it. Any ideas on that too?!?
I'd be gutted if it broke!

yes/no, there is a valve inline, it'll only vent if the pressure gets too high I believe.

Thats what I thought. I think tomorrow I'll give the filter and the general area a good clean up.

I'm more concerned about the noise to be honest. Sounds sorta like a tap, but it's only intermittent. Think that'll be a garage job, unless Carl comes along with any ideas!

noise sounds like a loose spark plug, i got that, on the same cylinder too LOL took the coilpack out and it was covered in soot Roll eyes

from what i've heard this 'valve' thing is just a load of wire woll type stuff, like in your breather filter Huh? and i really can't see the benefit of reattaching the whole thing and letting oil be sucked into your inlet manifold Huh?

Ok, after further investigation, noise doesn't seem to appear if car is driven lightly, say below 3500rpm. Over this and it seems to make the noise. Possibly a sticky valve?

Worthwhile using an engine flush??

Ta!
