RE: Fouled plug, Cylinder #7 - 2002 MERCEDES ML500 - 163 TYPE - CYLINDER #7 Oil Leak?

I have a bad valve, piston ??? causing a fouled plug in cylinder #7.
Burns through 1 quart of oil every 400-500 miles.
Suggestions please ?
Many thanks

Maybe you can remove the plug and use a cheap bore scope to actually look inside the engine. You need to do a hot and cold compression test and a leak down test. Those tests will give you the condition of the cylinder. Chances are you will be doing exactly what Mattml indicated, finding a another engine. Good luck.
