last night i drove through a puddle at about 50ish mph and it slowed me right down. didnt think nothing of it and went home. this morning i drove the car abut 2 miles and all of a sudden noticed a very high pitched noise coming from the engine area. happens at idle and while at revs and speed but not when under load regardless if the clutch is engaged or disengaged. i have been driving the car for about a hour since i noticed the noise and it seems to have got worse!! any ideas??
