Could someone provide the part number for the breather hose? On the 300SD, it's a two piece setup. The plastic piece that connects directly to the valve cover, then there is an L-shaped hose that connects to that and into an elbow on the intake. I need the L-shaped hose that goes into the elbow.

Also, that little trim piece around the ignition (looks like there is a rubber neck too), does it just pop out? Looks like someone replaced mine with a piece of black wood and some screws.

What are the best windshield wipers for this car? The standard metal ones or the one piece units?

Lastly, is it safe to spray the bottom of my engine with soapy water from one of those DIY car washes? I'm hoping that will remove most of the oil and grease so I can see where the leak is coming from.
