It is a '87 190E 2.3, dosn't have any fire at the spark plugs so it dosn't run. Happened suddenly in my driveway thankfully. It has 197K on the broken odometer so I am going to guess 230K miles.
It seems to me that it must be the timing chain. I pulled the rotor stand out and could feel the horizontal drive shaft and gear (oil pump drive shaft?) freewheeling.
Drove fairly well up to the end. Some rough idle at times but only on idle, ran great.
