i nave a 5cyl on the engine stand,that completely rebuilt.all my engines start with new sleeves and every part either meets mercedes new engine tolerances or get replaced with new.
if you are interested i would supply and install the engine with a rebuilt tranny. mike prott of louisville rebuilds all my trannys. you would have 4500 in engine,1200 in tranny and800 in labor.
