On 2 of my V6, I have oil leaks (one quite a bit, one minor).
On the 2.7T, I already changed the valve cover gasket (passenger side), but even then suspected it is the cam chain tensioner gasket (but too much work at that time).

Before I plan for the job, I found this:

"I read that Audi had put out a TSB telling their dealers not to change tensioner seals/gaskets B4 replacing the PCV components..a clogged PCV system can raise crankcase pressure and force oil past a seal that is still good. I started having some leaks (V6 has two tensioners) and smelled burning oil from the rear seal dripping on the exhaust..changed the compete PCV system (all hoses and the "suction pump") and its been almost a year with no more leaks"

So I would like to "replace the PCV components" (makes sense to me that if the PCV is clogged, the higher crank case pressure could force oil out a not so great seal"

Does anyone have 'how to' and what is involved changing the "PCV components"?
What are those, where are they located?
