ok... while in the process of replacing all the belts & water pump on my M20 engine, i've really run into something totally unexpected... when putting the new timing belt on, i've discovered that the camshaft sprocket is 180 degress off, exactly 180 degrees... the sprocket has never been tampered with as far as i know, nor was it mis-aligned so tremendously in the process of taking off the original belt... so essentially, the engine has been running with a camshaft sprocket completely wrong... is this possible? did somebody just take of the sprocket off once and put it back on incorrectly? do you think i should risk it when i restart my engine with a possible mis-aligned camshaft?
