WHAT WOULD HAPPEN IF YOUR bearing clearance IS TO TIGHT OR TO LOOSE WHAT WOULD THE MOTOR DO WOULD IT AMKE OIL LIGHT STAY ON OR LOW COMPRESSION
COuld you please be a little bit more specific?
your question is very vague. If you are talking about the main engine bearings… a badly worn set can allow more oil to flow around them and create a minor drop in pressure causing your oil light to come on very dim…
Regardless of that if it is being illuminated at all get your oil pressure checked by a mechanic, or search the forums here to find out how to do it yourself.
it could be a failing Oil sending unit or something far more severe.
