Hi all. 2002 SE Zetec Dohc.
Have a collapsed vacuum hose, need to know some specifics to tell the guy at the parts dept. The hose goes from the back of the intake, right below the throttle body, and runs to a pipe under the coil. Whats the official name for this hose? Also, I've never seen a clamp like the one on this hose. Doesn't appear to be the squeeze type or the regular type you loosen with a screwdriver. Almost looks like ya gotta pry it off. Any suggestions?
PCV (positive crankcase ventilation) hose.
Very common problem that they collapse when old.
Also, you have to cut the crimped clamp (not reusable) of the hose to manifold and use a new hose clamp; screw or squeeze type-doesn't matter.
Buy the factory parts, they're perfect. They just get old, hot and brittle over time. The front one is about 4 bucks, and the rear is around 6 bucks. Cheap enough to do it right. Common problem. I was able to get to both from the top fairly easily. Good time to replace the pcv too
I think the person who replaced mine didn't even use a clamp. Guess he figured the vacuum would hold the hose in. I think it's been okay for years now.
