Purring like a kitten...

OK thanks very much for the break-down, now where can I get the PCV valves from? Are these standard parts I can get from AutoZone or Pep Boys? Is there a specific part number? Thanks again for you time.

To change the PCV you basically want to be standing in front of your VX with the hood up. Take a look at the plastic cover on top of the engine. It's held on by four rubber grommets, roughly located at each corner, that seat onto metal studs that are in the intake. Grasp both sides of the cover with your hands about the middle of each side, then pull firmly but slowly straight up with a bit of a wiggling motion. Keep a sharp eye as sometimes the grommets can pop out of their holes and fall somewhere difficult to get at. Once you have the cover off it's a good idea to put any grommets stuck on a stud or popped off back in their respective holes, then set it aside.

Stand in front of your VX again and look at the top right side of the engine, just above the coils nearest you. You should see a hose with a finger-clamp retaining it on a plastic fitting the goes into a rubber grommeted hole in the head. Actually, it's best to already have the replacement PCV valve on hand, so you'll know exactly what you're looking for. While holding the PCV valve firmly with one hand, use the other to pinch the tabs of the finger-clamp together and work it a couple inches back up the hose. While still holding the PCV work the hose off the valve fitting. Once loose, then wiggle the PCV out of the grommet paying attention as the grommet can sometimes fall into the head if worn. If it's really loose and deteriorated just take it to your local auto parts shop and get a replacement, they're cheap and generic.

Reverse the above procedure to install the new valve. It's that easy!

Yep, standard stuff especially since we share the same engine across the Isuzu light-truck line. I order mine online from AutoZone.com when I get filters and usually get four of each at a time, then again we've got three Isuzus right now and I included routine maintenance with the '01 Trooper we just sold to a friend.

In any case, if you go to the store you can usually look up the appropriate brand part number in the book there. I usually get the Deutch which I believe is PCV193, but double check that.

Hey Joe,

My engine was replaced in 2003 with what I was told is an updated version of our engine. As such, my PCV is made of metal and is integrated into the housing. Do you know if I should be concerned about changing the PCV? In my case, that would involve replacing the housing. Do you know if 2002 and beyond 6EV1's were cured of our PCV/oil problem?

All that I've been able to find on the "improved" engine is that the baffle inside the head was changed slightly and the PCV valve was switched to a screw-in type as most of the issue revolved around the sealing of the valve.

As far as changing the PCV, you should check and change it regularly on any engine equipped with one. That's just a common maintenance item, and one that's all too often overlooked.

I've been working a lot lately on my Mercedes biodiesel project car and you should see how the crankcase is ventilated in that thing. Simple baffle in the valve cover, internally baffled rubber breather hose from the valve cover fitting to the air cleaner, which has an internal cyclonic separator pot that drains separated oil back into the oil pan and a venturi tube to feed vapor into the turbo. Just got it all back together last night after completely disassembling, cleaning and servicing it. There's an o-ring on a check-valve that the oil return tube fits over on the top of the oil pan that was a minor pain to deal with, but hopefully it'll be nice and tight and not need any more attention for some time. PCV valves are much, MUCH simpler!
