Mercedes Emergency Spark Plug Thread Repair - NEW SOURCELET

Installing steel threaded spark plugs in aluminum heads is risky business. If you are not careful it is easy to damage the fragile aluminum threads. In a few cases I have seen spark plugs blow out of their holes while the engine is running. And does that ever make a loud racket! Heavy handed mechanics often cross thread the plugs during a tune-up and you wont even know it until you go to replace the plugs at some later date.

I would encourage you to either replace the plugs yourself or make sure you go to a competent and seasoned mechanic who takes care and pride in his work. But, if you do find yourself in a situation with damaged or destroyed threads on one or more holes, this Sourcelet explains your options for repair without removing the cylinder head from the engine. I will even show you some tips on how to prevent damage in the first place. A must read for any Benz gas enthusiast!
