200tdi oil loss

I thought that I would enlist the braintrust on this site to help me figure out how to proceed with my 200tdi...

Symptoms:
- losing 1 quart of oil every ~500 miles
- lots of oil in the air filter canister (coming from valve cover breather hose). The entire quart is not coming out this way.
- slight oil weeping at head gasket. slight.
- slightly down on power. maybe?
- fair amount of smoke from valve cover if you remove oil cap. How much is normal?
- a little more smoke out the tailpipe than normal?

Potential causes:
- engine experienced an overheating episode. Can a bad headgasket alone cause this?
- bad piston rings?
- valves?

Other:
- no oil in coolant or coolant pressurization issues
- oil return line from cyclone breather to sump is clear
- cyclone is clear

Before I rip everything apart wanted to check in so see if you guys had any additional thoughts. Thanks very much for your help in advance.

-Pierre

Blow by. unhook hose from filter canister and rev engine with your finger over the end of the hose. Is it pressurized much ? If yes a leaking head gasket or rings would be the cause. Overheating an engine tends to take the spring tension out of piston rings. They no longer push out against the cyl walls as hard as they need to.

Yah, you should not have smoke from the oil filler... Probably a head gasket as that is common. Could be rings too, but checking the head gasket is quick and easy.

Quick and easy as in removing the head, or something even easier than that? Thx!

There's always (~2 years) been some chuffing coming from the breather hose. Now it's just more pronounced. So likely rings...thanks for the confirmation.
