99 A6 2.8 Valve Adjuster Repair

Came out to the car last Sunday to find a puddle of oil under the car..
Looked at the dipstick and no oil registered. Didn't trust driving it to
the nearest Audi dealer (9 miles) so had the hook come and get it. Turns
out the problem was something called an oil separator (possibly in the cam
adjuster area?). The write-up indicated the "cam adjusters froze causing
undue oil pressure". This caused the oil to damage the gaskets and caused a
major leak.

Anyone know what an oil separator is what it does in the context of the cam
adjuster mechanism?

So the Audi place fixed the CAM adjuster oil problem; however, they did not
fix the entire oil problem. Seems to be leaking oil from the front left
portion of the engine as well. Took the car over to the local oil change
place and had them remove the shroud cover from the bottom and went
underneath the car to take a look. Oil coming down from the vicinity of
where the dip stick meets the engine but lower. Looks like there might be
an oil cooler in that general area but lower, behind the bumper. Looks like
high pressure hose in the area.. Could it be cracks in the hose or possibly
a weak clamp?

Turns out the head gasket installed on leaky side was bad. Had to replace.
All is well now. Also found out what the oil separator does. Similar to
something you would probably find in a diesel engine, the purpose, as the
name suggestes, is to separate oil from water vapor and other contaminants.
The separated oil is sent back to the crank case. The contaminates and
water vapor are rerouted either to be burned or eliminated to the outside
atmosphere via a breather tube..
