I discovered yesterday that my engine is 1/2 tooth out of timing at the crank and front balance belt sprockets. I believe this is due to the timing belt being stretched b/c of improper tensioner settings. Could this be detremental to my engine, or just make it run a little rough? I was wondering b/c the closest Mitsubishi place is about 60 miles from here and i'll have to drive it there to let them fix it. Thanks.
