So i was driving my car yesterday and everything was fine. Ran great as always. On my way back from my destination i stopped at a spot to get a bite to eat. When i got back into my car i noticed a rattle sound knockin noise. Its not too loud at idle but when i rev a little or go it gets loud. Kind of sounds like on the passenger side. Oil is good i just did oil change 1200 miles ago. Doesnt sound like exhaust leak but i will be getting under car to do some investigation. Any idea what to look for? Will smog pump cause a sound like this? Also it still drives great. Just knocks like a bi***! Any ideas will help. Thanks

Take your serpentine belt off. It could be the air pump

Hopefully its not. I have to smog it next week. Ha fukin my luck. So if i get a shorter belt it will eliminate pump right? But i dnt wanna spend money on a belt i cant return, plus i have to smog soon. Any way to test if it is the pump

Start the car with out the belt and see if it still does it. If it does use a long screw driver and put it to your ear. It should help you narrow it down to where it's at

that doesn't sound like engine knock. Your right, sounds like the starter is staying engaged [ 2014-08-19, 02:16 PM: Message edited by: 92_5.0 ]

it's been awhile since I've been under my car, I'm pretty sure you'll need a long extension. I hope the flywheel isn't chewed up yet.

it should be pretty easy with the right extension, if you don't have one grab a cheap one from harbor freight if you can
