That's certainly what it looks like with the diaphragm built into the top of the cover. But I thought there was an environmental regulation that required those fumes to be recirculated through the combustion chamber?

 

I haven't taken one apart but I'm sure it recircs normally for the reason you mentioned, the diaphragm might just be a pressure relief if there's more blow-by than the intake can handle (I think I've heard it relieve when cold at high elevations). First noticed that on a cold day at 8000ft, but it's gotten more common over the years so maybe more blow-by as the motor ages?

 

There is a passage way in the cylinder head thru the timing chain cover and to the other side of the cylinder head and then into the intake air path of the engine

The small hole in the lower right of this picture is for the PCV gases



And at the bottom of this picture you can see the hole that allows the gases into the intake port

Back to the original issue

This is for the 3.0T but the procedure for the 3.2 is identical

 

Ah, I did not notice that little hole when I had the cover off. That's what had me stumped, I was looking for something more obvious like a hose.

If those pics are your LR2, you have some clean valves! Which fuel cleaner do you use?

Thanks!

 

Mine look the same. I use mobile-1, but any synth oil will have good cleaning properties, basically it acts like a solvent and doesn't have all of the random hydrocarbons found in dino juice which will end up as sludge and deposits. Last used car I bought had been run on dino oil, and the valve cover was pretty cruddy... after about a year and 20K of M1, the crud was gone, the valve cover was shiny, and my gas mileage improved by about 30%.

I buy mostly chevron gas since techron is pretty well accepted to be good stuff (philips 66 also used to have techron but I don't think it does any more). Any designated "top tier" gas brand will have more cleaning additives, so at the very least go with that if you're planning on keeping the car for a while.

 

Merlin,

I agree

- Mobil 1 0W40

- Top Tier Gasoline "it has a Techron like cleaner in the fuel no need to add more"

- PCV changed at about 100,000 miles, it wasn't broken (because I am a bit paranoid)

- Spark plugs Denso Iridium changed every 50,000 miles (did I mention that I am a bit paranoid)
