I have a 300D Turbo with about 180,000 miles and I have determined that oil is passing from the valve cover to the air filter through the tube that conects them both. Why? Is it blow-by in the valves or the the piston rings? Please advise. If you want me to call you to talk me though it send me your number.

TODD ARE YOU SURE ITS COMING FROM THE VALVE COVER BREATHER OR IS IT COMING FROM THE SEAL LEAKING ON THE TURBO AND ITS SPRAYING IT BACK INTO THE AIR CLEANER ASSEMBLY AT IDLE TIME I HAVE SEEN THIS HAPPEN AND A TURBO OVERHAUL SOLVES IT AS FAR AS COMING FROM THE VALVE COVER SOME HAD SMALL BREATHER HOLES IN THE COVER NEAR THE BACK AND THEY GET CLOGGED

I am pretty sure it is coming from the tube running from the valve cover to the intake. I will check it out.
Normal Operation? If you ask do i run it under normal operation? Yes, every now and then i kick in the turbo. But i run it about 10 miles to and 10 back to and from work, five days a week.
I will try to change out the valve cover gasket this week-end as i have one already. I also loosened the oil filler cap and checked the pressure. The cap almost jumps all the way off. Do i need to replace the rings? I will have to get my wagon on the road to break the sedan down and replce the rings. A good charge on the battery and repair the hyd line leak and she will be running again.

That is called "sump compression" blow by or what ever, if there is some smoke comming out of your oil filler cap, then it is time for new rings...

As I said, normal operation, especially for an engine with that much blow-by. If the car runs well then don't worry about one bit about replacing the rings until you have compression issues when starting. It's never simple as "throw in some rings". Once you get in there you'll find bearings, timing chain, tensioner, piston clearance, valve seats, valve stem seals and many other things that need to be done on an engine with that much wear.
