Took a look at a '91 W-126 today. 150K on the clock.

The vehicle was garaged for most of its life and the body is in excellent condition. Interior is also quite good, but not immaculate due to the mileage.

Maintenance consisted of just the basics.........shocks, brakes, tires, etc. No front end work of any kind.

The engine starts and runs rough with some injector knock. Heavy and extreme oil smoke. The event that precipitated this condition was sudden and instantaneous...........not the typical behavior exhibited when a rod bends.

I'm curious................from those with experience with this engine..........if anyone else had an incident with this engine that caused an instantaneous and dramatic increase in oil consumption.

I might consider purchasing it for the right price (probably about $1K or so).
