is the oil pump bad?
I have a toyota corona st190 4s engine 1993 model. Oil light flickers, metal
rattling noise when starting and then subsides along with the oil light...but
flickers and stays off most of the time. mechanic says its not the oil filter
(changed it anyway) but the oil pump may be losing pressure. Not the
sensor switch he says as oil light would stay on all the time...and not go off
or flicker.
Does not know if there is another oil filter inside the oil pump...
any suggestions please?
