I tried to take a picture of the injector pump, but the darn batteries on my camera died. I'm charging them now and will take a picuture tomorrow in the sun light.

I'll try to describe my injector pump.

* It has a red cap that says OEL.
* The pump is located on the drivers side of the engine.
* There is a little rounded tube between the injector pump and the engine. Is this the overflow tube for the proper oil level? I'll try to get a picture of this tomorrow.
* I've read that I should put 30W oil in the pump - is this correct?

More tomorrow. If you can provide assistance on how to properly identify the pump for better diagnosis, please reply. I didn't see any obvious drain plugs, but it's really hard to see the pump very well. Mercedes really didn't do a very good job of making things accessable on this car.

Please reply and thanks.
