PVC Valve and Hoses

[MiniMike]

Do I need to keep the PVC Valve and hoses on the Honda engine or can I just remove them and block off the tube? Would this casue any problems?

Mike, Why would you want to remove the PCV valve? You can put a small filter on the valve cover as some have done but the Honda apparently needs to recirculate the fumes for everything to work properly. This comment is mostly from reading the forums and not personal experience. Plus it pools some of the oily crap afterwards on the engine. That's why they use catch can systems. JS

Different honda engines have the PCV in different locations. Most have a pipe from the bolck to a valve inserted into a cut out on the intake manifold then a pipe from that going to the intake itself.

Dont block off the tube, you do need it.
Its better to run a catch can system from the valve so you dont put the oily crap back into the engine.
The PCV needs vaccum to operate, you cant just put a filter on it, tho the crankcase breather pipe can be replaced with a filter and no side effects.

Thanks, I decided to leave it in, was just looking at cleaning up some hoses, as it's crammed under there. Mine does go from the rear of the engine up through a hole in the intake manifold between the runners, and then onto the intake manifold like you described.

Where does it go if you're not using a Honda inlet manifold ?!! Suer I'll find plenty of other pipes and hoses with no home to go to when it comes to assembly !!! :lol:

Then I would put it into a catch can and route the other end of the can to your vaccum system. Just dont leave it unconnected.
