Droaning Sound In Motor After Belt Change

[mattyg]

Hi there,

i found a constant droaning noise in my rb26 a day after i put in a new timing belt kit and water pump. i red up on it and alot of people said the gates racing belts make noise for a while after instalation due to running them on factory cam pullys so i didnt warry about it. about 2500ks have gone by and its still there, so i have just taken the top belt cover off to check the tension thinking it must have been the problem but its not to tight. When i first herd it, it sounded like it was coming from the rear of the motor and then a couple of days later the front of the motor, posibly the cam bearings i thort at first (due to a tight belt). does anybody hav any ideas? it would be much appreciated. thanks

Usually they settle down but depending on the resonance and acoustics of your bits n pieces on your motor, particularly your timing belt cover, it can remain. My belt has continued to do it after the change. its less than it was when it was first done but still there... It stops completely when the timing belt cover is off. But that isnt exactly the fixt i want. I then replaced the rubber seal around the CAS as well as the bolts n it is 70% better. Just harmonics methinks seeing as it goes away completly when the cover is off...
