need some solid advice on whether to sell or keep this w140

95 s500. its got 238k miles, i jumped the timing chain a tooth when fixing a serpentine belt(turning motor over backwards) so i ripped the whole front of motor apart(timing chain cover) since i thought at the time that was where the tensioner was located) --laughter--. So anyways i reset the timing and put everything back together that was needed just to start it up. I started it and it still had no power like it did when i bought it, that same day i figured out the problem was the ets wires insulation--more laughter i know--, So now its decision time, since motor isnt fully together yet do i buy all new tensioners and chain and replace everything to keep? Reason i ask is it has 238k miles. I found alot of thick oil gunk behind the distributor housings, is this normal? or from serious lack of oil changes? Also how do these transmissions hold up? It seems like it has a serious leak somewhere in the trani, havent dived into the cause yet, i assumed from front bein lifted on jackstands(which is still strange). And last but not least how to these headgaskets hold up?? also if a head gasket went bad do these blocks strip out where the head bolts go in like many other aluminum engines?? sorry for the long post i just hate to put all this money and time into this thing if its not worth it at this point. just to clarify i bought the car with a bad serpintine and bad ets so i never even drove it nor have i ever drove an s500. thanks so much for any help.

Head over to the 140 section and take a look at the stickies about common problems. Also, use the search function once your in the 140 section to locate threads about your specific problem.
Example go into the 140 section, hit the search button (top right) and search "transmission." This will give you info on your leaks as well as opinions on longevity.

Finally, if you do plan to keep it and work on it, search each repair before you start, find out what problems others have encountered, and other important information.
