To my wife's spite$upsidedowness I bought another 300d - former w126$280se-1985, that had been turned into a 300d (in spite to all officials here in Romania whoi would do all to stop you changing engines of cars) non turbo, engine year unknown for me; paid 2200 euros and started fighting all enamies that came to my yard with the "new" car. Here you don't find many w126 and I always wanted one.
Here's the list what I have done in one month time, kind of too much, but still acceptable - some things helped much by reading posts on this forum:
changed wind shield - 150$
changed left guide rod - with a "nice" solution for remofing the old one from the aluminium mount that is scorching the old ball joint rubber with a propane torch;
changed three stuck callipers & brake pads
repaired e-brake with a turkish kit - 20$
repaired drivers lock which was different by changing the little brass keys inside until it fit the key
repaired tle left rear door lock as it didn't open - only locked
tried to remove some ancient alarm - some spagetti wires stil there since I don't know where all belong
replaced left engine mount - smothened the jumping 300d a lot
replaced the lower oil pan $ oil as it leaked - former owner used 5w40 ????!!
replaced the front pulley and main seal as I found the big crank screw almost unscrewed and the pulley turning on its own
fought the little too high operating temperature (90 & upper in trafffic) by drilling holes in termostat - thanks Diesel Giant- and cleaned the radiator in my tub - to my wife's desperation ; was full of yellow cheese that got finally out after one week of repeated flushes - tried some 6 t-stats until going for the dewalt drill;
The injection pumps here (european version I think) don't have a rack dampener bolt as seen on forum, but something similar - adjusted and stoped the engine's cha cha cha to a bearable level
Of course adjusted valves - I have no special wrenches, fought 3 hours to get done- experience gained with my other 300d w123
replaced alternator & repaired starter as they were almost dead
fused the low beams lights - previous owner didn't use them for one year!!!!
cursed again the rear defrost - my 4th MB with no rear defrost working
put grease & oil in doors $ sills to prevent rusting
Still fighting the ABS eternal glowing light - still no result, even if I replaced a sensor and checked relays
Adjusted the shift rods as they had been torn by a destroyed flex disk
welded the exaust as I had some tractor noises at some point
replaced some lug bolts as the prevoius owner used 2long&thre short ones at alu rims almost stripping the threads at all weels
replaced tie rod ends - left- checked other ball joints - stil good for now
and many other small things that I already forgot about

This is about it, sorry for the long post, but I decide to le you all hear from me; kind of lonely here fighting all these problems, still far from end
If someone has some ABS related charms that might help me please do let me know
Thanks
