Hey Guys,
I just did a timing belt and tensioner on my 1.9 AAZ, and everything is good. Except, now I hear a whirring noise I didn't hear before. I set the timing belt to be able to rotate to around a 45-degree angle. I hear the noise pulse by the injection pump (fades in out and out, it's quiet then it's noticeable and then goes away). I've run it for about 2 - 3 hours and very minimal driving on it. Is this anything to be worried about or is it normal?
