If you think it is the belt, try putting some baby powder on the belt. The baby powder helps lube the belt and pulley groves and will reduce or stop the noise if that is were the noise is coming from. The baby powder worked wonders on my pickup belt noise. The only problem is the powder washes off so I just sprinkle on some more powder and the noise goes away. I replaced the belt three times and a new belt (Dayco, Gates, and some other cheap brand) would only last about 6 months and the noise would start to come back. I even laser aligned all the pulley's but the noise would come back. I think the pulley grooves were worn. After that I just used the baby powder.MacGyver wrote:Mine does that when cold. I think it's the belt. I want to try a gatorback belt to see if the noise goes away.
think this might be on track my mechanic friend said take out the synthetic oil and put a 10-30 regular oil in it and check the noise. did this last night and the noise is just barely noticeable now. think with a few more miles on it will get lots better.dragon64 wrote:The noise you hear is from the hydraulic cam gear actuators in the variable valve timing system. The noise goes away as soon as the oil pressure builds up after starting the engine.
