chain noise 2002 tt


Recommended Posts

2002 996tt @51k miles

has a chain niose on rt side.

kinda, a clicky-clack,clicky-clack,clicky-clack....... at idle...... off idle goes away.

listening with a long screwdriver you hear it on the rt chainrails mounting pins.

so we are thinking a worn rail or pad on the rail.

what about tenioner....low presure at idle ?

or chain slack......... at low idle ?

It's a new owner he never noticed it till I brought it to his attention doing and oil change.

now paranoia has set in and he hears it and wants it fixed,

I have motor out ,Valve Covers off. getting ready to remove chain rails to inspect

sorry but what is "LWFW" ?

ok i searched ....

no it doesn't have light flywheel.

I know what that sounds like.

this in the rt chain area.

flywheel noise usually goes away when clutch is applied,

this doesn't.

Almost every 996TT does a rattling sound at idle...It should go away above 1000rpm...If this is the case nothing to worry...However i can not tell whether this sound comes from left or right side...So if the sound you hear is focused on one side...it might be something else...
