190E green spark plugs
I recently bought a 1993 Mercedes Benz 190E 2.6L, after riding it for a while I decided to check the spark plugs, and turns out those are "green", like antifreeze; a mechanic told me ir requires to open up the engine and repair the engine head. So, I will proceed, but, what other stuff should I change to have a best performance-engine for a few years? Gaskets? any other stuff?
Please help me to get the best of my MB with your anwsers!!! Thanks in advance =)
