Today , This guy at jiffy lube said that he hand-tightened my oil filter on my 300e, is this ok?.. He said that if he used a oil wrench to tighten it may dent it and it would then be useless, I am sure he was just lazy, What should I do?. I have only drove about 15 miles to my home, Do I need to buy a wrench and do it myself?. Damn lazy kids..I am sure the engine will jiggle it loose. Or is this kid right?..thanks
Also, I went to change my air filter, and when I raised the metal lid up , I broke off this rubber piece connecting to the engine, it looks to be a breather tube or something, it connects from the top of the metal air filter lid to the engine, anyone know what it is called?..or part #..thanks
