This is a M104 engine?

#1 boy finally decided that he would show some interest in his car. We had been working on making the car functional enough to pass state inspection so it could be registered. Got that out of the way and he slacked off. With the W140 on the road, he wants to put some shine to it. Anyway, he drags me out to see what is making the grease spots on the street where he parks. From the top it looks like nothing, but I get him to put it on ramps and take off the covers. It is a pit under there and the belly pans are loaded with asphalt and crud. Gave the pans a good scrubbing and they are ten pound lighter. We scraped the crap off the underside of the engine. Soaked it with citrus degreaser. No matter how much we dosed it, the stuff kept flowing off black and thick. Wire brush to the cruddy parts with thick coating and found aged cosmoline or some yellowed coating. Brake cleaner cut the mounds of gunk on top of the sub frames. Boy got it off ramps and drove it in the rain. When he got back there was lots of oily drips all over the place. Looks like there is a good leak going on. Door locks and other vac stuff is not working. I got tired of dealing with the kid whining about oil and gunk getting in his hair, so I told him to work on the vac lines. I have no idea if the pump actually works, but he got happy playing with my vac tester and making the door locks work. We will have to figure out the rest of that mystery when he has another day off. I spent the afternoon with the steam machine blasting away at the built up snot on the oil pan and the rest of the stuff under there. It was flowing and plopping all over, and the crust was disappearing to the point that what was once black was beginning to look about 150k miles newer. I finally got it clean enough that any new black drips will be very obvious and I will be able to see any real leaks. And the underside is all shiny and pretty. Even found that the suspension may have been replaced within the last 12k miles. All the bolts, once cleaned, were looking like new. I can see that this 300SE could be a sweet ride for show and shine. Now I am going to have to spend a number of hours with the steamer getting Frosch ready clay
