I have 96 V6 just changed the oil, had 5w 30 Mobil 1 they said 5w 20 (Castrol got it for free) would be fine I put that oil in started making a faint tapping sound switched to 5w 30 Mobile 1 extended performance sound still there any one have any idea of what it could be? Probably might take it to a mechanic on the weekend. My poor pony

Here's the link to the video clip on the tapping sound hopefully nothing serious

First take the front belt off and check all pulleys and idler pulleys for bad bearings.

Next, read the following post. Something is making that whine.
