ok so I've run into an issue. I'm hearing a nice little rattling noise under the hood.
first thing I thought it was before lifting the hood was timing chain tensioner. after lifting the hood and looking around it sounds like it was coming from the headers. I recently installed a pacesetter header and at first it sounded just fine no rattling or knocking, sounded just like it should. I went and re-torqued the bolts and still getting the same noise. I'm going to change the tensioner just because if it isn't the problem it will be later down the road. I guess I'm just wondering if anyone has run into the same issue. Just a little extra info I just rolled over 36k miles.

My car does this when I put cheap **** gas in it.

 

Sc coupler maybe

 

Well I guess I'll just start replacing stuff till I figure out what it is

 

i have the same problem let me know what it is

 

Dunno, last time I heard a rattling noise, a bolt holding the timing chain in place backed itself out.... it wasnt pretty.

 

im also hearing timing chain tensioner issues

 

got the part in today, will post results after valve cover is done drying since I figured I'd paint it today.
