I suspect most of you guys are so smart you don't need to look at instructions, but the rest of us need guidance.

We have borrowed a Haynes repair manual from the library, which has been a great help with several things, but sometimes it doesn't seem very accurate. For example, there is a whole section called "PCV valves", but apparently the car doesn't even HAVE a PCV valve (other than the heading, it isn't really mentioned, but it did cause me some confusion. It's not hard

). Also, we are thinking of rebuilding a motor (long story, on another thread) and the manual talks about having the cylinders re-bored. My husband phoned this place that does that type of thing, and he was told that there are cylinder sleeves in Mercedes. Great idea, and much cheaper than re-boring.
Does anyone have any 'other' manuals they would recommend? We also had the CD version of the 126 manuals, but we currently own a 300td wagon (1981).
Thanks!
