just google carbon issues for Mini cooper S and you'll see some good pictures. I owned a '07 cooper S and the carbon issues were horrible and i only had 60,000 when i sold it.

Who is not calm? I'm almost always calm. I'm just worried about "greenies" going after people and making their lives miserable.

The Audi/VW, Mini issue is well documented and a severe problem. So, I ask again. Does anyone have actual photos of THESE engines with carbon buildup? I have heard that it will buildup or does buildup. I want to see proof. There are plenty of these engines driving around. Can we get a photo or two? Anyone who has pulled one apart have pics? Anyone have boroscope pics? Anyone?

My thoughts and opinions....
I do have a borescope and have looked at what it would take to actually get the camera to the intake valves. Looks like it may be easier to just pull the intake manifold to look. Just because my engine or another engine has deposits,or not, doesn't mean YOURS does or not. I think a lot of factors play a role in making deposits. Direct Injection has been around for a while now, and I would hope the manufacturers are addressing the issue. So it may be too early to tell. There is also the question of how much deposits can be on the valves before you notice a difference in performance. I only have 6000 miles on my car, so I'm not concerned at this point. If you are, maybe look into pulling the intake manifold back and see what your engine has.

My concern is marginal. I don't believe the evidence available for the Audi/VW-Mini issue applies to the focus simply because it's direct injected as well. I think that a lot of this talk is a waste until there is evidence for concern, supported by proof, regarding our engines specifically. I would love to see the pics. I have searched all over and have not found any yet. And, there are a lot of these engines running about with a lot more miles than my 40K. I am not stating there is or is not a problem, just that if it was a problem there should be some documentation of it by now.

Thread got somewhat off-track ...

Back on topic -

The Helm manual shows a PCV valve on the oil-air separator as part of the assembly, but no details on it.

Helm image does look to me like the valve in this thread: http://www.focusfanatics.com/forum/showthread.php?t=361177

Questions:
  • 2002 Focus Maintenance Interval called for the PCV valve to be replaced every 100K miles. I didn't see that for the Gen III, but is it still the same interval, or longer, or shorter?
  • At this point, does anyone know if the valve can be replaced separately, or does the oil/air separator have to be replaced?
  • Is it possible to replace the valve from underneath the car without removing the intake manifold, or does the manifold need to be removed?

Thanks in advance!!!

You have obviously never worked in EPA compliance testing for that is incorrect. The unburnt hydrocarbons discharged from the road draft tube were a huge contributor to air pollution. In addition, the draft tube depended on air flow under the vehicle to function. Vehicles that idled extensively in traffic often suffered from sludge buildup.
