Rattle Noise 00 blazer
Alright i posted about a weird noise from under the dash. a few of you said vaccum hoses and pcv valve. Sure enough the noise was comming from the pcv. and the vaccum hoses were crimped and dry rotted. I replaced all the bad hoses and the pcv. Noise went away for a day and now its back! is this a warning to a bigger problem in the motor? is something wrong in the valve cover?
