I must say that if you did all that for $2,000 you must be one whale of a mechanic. I'm a low grade DIY'er but I could never acheive what you did. My biggest concern is the timing chain and rails. At this point I don't know whether or when it was changed. I can't do it myself and my mechanic will not get inside the engine because he doesn't have the specs. That leaves a Mercedes dealer and you know what they charge. Anyway, I appreciate your detail, and I'll pass it on to my mechanic.
