H3 PCV valve - Where is it?

[SELWA]

I removed the air cover above the engine and tried to find it the other day and have no idea.

If i am currect ? Our trucks don't have a PCV valve, just an oil spray baffle inside the valve cover with a vent to the air intake resonator box through a rubber hose. What year and engine do you have ? Is it running ruff our off ? Or are you just doing routine maintenance .

Funny how CTC was able to get me a part number anbd order it in! $5 so no big deal, I cleaned up my throttle body and it seemed to help my issue.



This is what was happening:



Drives fine, and at full stop the idle was fine, but right before I stop the idle would SOMETIMES idle close to 500rpms and a few times it stalled. This happens more when it's colder. If I tapped the gas it went back up. Very strange!

Well you said you cleaned your throttle body . Injectors also ? How old are your plugs ? Yes that is low, and stalling is VERY UNCOOL . I hope your head is not going ? What year and engine to you have . What is the mileage on your H3 ? Are you in Ontario ?

I cleaned just the visible throttle body. Having 4 kids leaves me with little time to wrench too much. It's a 07 with 140K on it. During the spring and summer I had no issues at all, just when it's colder out. However after the cleaning I've had the symptoms mentioned go away! I'm right beside you in Milton! <img src='http://www.canadianhummerclub.com/forum ... rgreen.gif' class='bbc_emoticon' alt=':mrgreen:' />
