Hey guys n girls. First post here. I'm from Australia. I have a Holden VT series 1 wagon with a L67 from c vx Calais fitted. I have had the engine in for around 2 months. I have changed all pulleys apart from harmonic balancer, including a new idle tensioner .I have changed the belt 4 times,using different branded belts in the hope that it may fix the problem. . I have tried using electrical lube/dry soap/belt dressing/armour all etc etc. Nothing seems to work. I have changed the snout bearings and also the coupler for the blower. The belt squeal is doing my head in. I have an aftermarket 10psi pulley fitted.the squeaking was happening before I upgraded the pulley and it's doing exactly the same with the new 10psi fitted. I'm using a 6pk1735 serpentine belt to allow for the smaller pulley. Any ideas would be great. Is it the harmonic balancer that I need to replace to fix the problem? I can't think of anything else it could be. None of the pulleys have excessive movement or wear as they are all new. Could it be that I need a shorter belt? I seem to be making 8-9psi consistently according to my boost gauge. It squeals on idle and gets conciderably louder as I accelerate. Under boost is painful as is drowns out the whine of the blower. Please help!!! Haha
