The idea of replacing the PCV hose with something that will not fail, will be a great improvement and should be done.What would you think of this. Top Speed sells a PCV valve block off plate (metal). That with a copper flare fitting, and using soft copper tubing to eliminate the 'rubber' altogether.
You would have no issues doing this , In my opinion on anything performance the PCV SHOULD NOT be going back to the intake anyway and the valve cover breather should not as well , vent them bothMy thought was to run a metal pipe either to atmosphere or a catch-can. I think it would be to tight a fit for a PCV to intake setup (good pics btw!).
Any carb/choke cleaner should work. Or 3M has a really good throttle plate & carb cleaner. P/N 8866. $7 a $8 at O'Reillys or other parts stores. It works really really good. I use it all the time to clean the throttle plate in the throttle bodies.I removed the intake manifold of my 2004 ZX5 2.3 in order to replace the PCV hose. The IM is coated with a wet carbon gunk, what should I ise to clean it and how?
Nice to hear it. That's a project I will need to do in the near future.Thanks for the quick reply. I bought two cans at a local CarQuest retailer, it seems to work pretty good. I do have lots of carbon buildup above the valves, that's not coming off.
BTW, I was able to easily remove the PCV valve from it's cover. With the cover off of the car I could use a needle nose pliers to grab and squeeze the locking ring at the two notches and turn counterclockwise, it came right off.
