Hello sorry for the late response,I purchased the parts from the dealer here locally but this only effects the car in colder climate as Michigan that is probably why nobody in Houston stocks the parts.
Hi, I was wondering if you can help me out. Did you buy your parts (PCV hose kit, valve covr gasket..etc) from the dealership....if not where. Every Cadillac dealership I have called in Houston does not have it in stock, and GM direct takes about 7 business days to deliver. Also has your car been running fine/better since your replacement? Have you changed anything else?
