Review on πŸ”§ Dorman 46034 PCV Hose Kit: The Ultimate Solution for Optimal Engine Performance by David Estevez

Revainrating 1 out of 5

Junk: PCV valves and breathers

Hose is useless. I replaced the PCV and hose on my 2006 Mazda 3S. I bought this hose because Dorman makes some OEM products for Ford. Less than a year later I started getting DTC 2187 which is a generic code. I found the hose was spongy and broke causing the vacuum to leak. It might not have been that bad, except that you have to remove the intake manifold to access it. Replaced it with an OEM hose. This product deserves negative stars!
