pcv drain tube

tdubb123 · 11-23-2012, 04:45 PM

the dealer did a safety inspection on my 2005 zhp and said the pcv drain tub is starting to leak. where exactly is this? how much and how difficult to replace?

If that is the only leaking hose then t is very easy to replace. That drain hose connects the oil dipstick tube/guide to the CCV.

In order to gain access u need to remove the air box and maybe the throttle body. Removing the hose from the CCV is easy. Just press on the release tabs and pull. At the dipstick there is no locking mechanism. Just pull and it should come loose.

Hope this helps. Good lck

No need to remove the throttle body.

I do them from the top with just removing the air filter box.

See the first link below in my signature for more info.

A bit tricky to get the old one off, but once you have the new hose and see the way the connector works, you can figure it out.

You may also need to slit the hose on the dipstick tube to get it released.
