ok i just did my dek swap and when it idles and stuff i hear a loud rattle coming from like the timing chain area....could it be my tensioner is bad and timing chain is loose??? has anyone had this problem before

 

i have a tapping noise at start up and it goes away after it warms up. i think a pully or chain tensioner is bad or i have a lifter tapping, im not sure.

 

the timing chain is loose. the tensioner needs to be tightened.

 

this is what im thinkin as well

 

can the loose timing chain cause any like performance problems??

 

forget performance....
dude a loose timing chain means your car is near death. if that slips or comes off while the engine is running then you are going to need a new engine. my uncle actually just did this on his 02 volvo last week. gonna cost 3800 bux to replace 9 of the valves.

if it is the timing chain then the next time you start the car should be on your way to the mechanic/dealership. dont drive it anywhere except for there.

 

is tightining the tensior a all day project or does it just take like a half hour??

 

all day.

 

It was the idler pulley

 

is there a guide on how to change the idle pulley??
