I just ordered a pully kit and will be installing it soon. just curious as to damage to the engine from this part as ive heard after a certain amount of kms the vibration in the engine can damage engine components... is there any truth to this?

 

search
but no, there are guys with 100,000 miles under their pulley and no issues

 

no issue except for a damage belt after 10K kms, bought a better one and still going great

 

there's a thread on this exact concern already. searching is your friend.

And like mentioned in that thread, i'd say 75% of RA owners on this forum have the pulley and people have put close to 80K on them with no problems. I mean if you want it to last for 200K then i doubt it.. i think the car would be done for before that... eh.. mitsu's.. haha
