Pcv valve location on 07 malibu 2.2l ecotec engine?

we have no Holden, here USA 12,000 away.
but PCV ,has connection to all engines at the VC, valve cover.
the other side is intake plenum vacuum side.
there are 2 pipes to the VC
1: fresh air from air cleaner to VC> ( input)
2: bad AIR ,crank case fumes to the PCV VALVE
DID YOU KNOW SOME ENGINE HAVE NO PCV VALVE
BUT IS JUST A FIXED ORIFICE/( LIKE MY JEEP 4.0l i6)
THE ENGINE TO IS PARKED OPEL
front pipe there top, look like fresh air to VC> to me.
googling the world for z16SE shows no valve sold nor examples
and one post said there IS NONE !

the service manual covers all that, get one?
is not this car really and OPEL rebadged to down under name Holden? the wiki on this car is horror to read. variants.
called COMBO C.
using

• 1.6L I4 8V SOHC Ecotec
• 1.6L I4 16V DOHC CNG Ecotec

the wiki got me to 2 engines. is yours 8 or 16 valve is the question.
Z16SE? (8v)

Names and markets

• Opel Combo - Europe (except for United Kingdom) and Chile before the rebranding in the end of the 1990s
• Vauxhall Combo - United Kingdom
• Holden Combo - Australia, New Zealand
• Chevrolet Combo - Chile
• Shanghai Auto Saibao SAC6420 - China

now the Yankee answer. and photo

IT HAS NO SUCH THING AND BEHOLD HERE.
HOSE 1 IS HARD VACUUM 0.6BAR and sucks fumes to the induction plenum
hose 2 is fresh air from the AC air cleaner.
hose 1 may have tiny ORIFICE inside, or not. but maters not.
what maters is hoses not cracked or plugged up
and the circle X below deep inside VC has filter three that loves to clog on high mileage (KM) engines, we replace that.




end PCV valve hunt that never existed nor is it SOLD IN ANY STORE says google .

Usually in valve cover...will have slightly bigger hose coming off of it

Thanks, Glad I can try, however, its very easy to locate. if there's a plastic trim/cover over the engine remove-it and set aside. The Spark Plugs is sitting right below the Ignition Cassette or Coil as it is also referred to, it may say ECOTEC on the cover, secondly, remove the electrical harness on right side of the cassette, it's just above the oil filler cap, then remove the four, 10 bolts and pull-up the Ignition cassette. All four Spark Plugs will be there for easy removal and replacement. Reverse actions will be in order... Here is what you will need to perform the repair: 3/8 in ratchet, 5/8 in Spark-plug Socket, 3/8 in extension 12 ins long and a #10 socket. For your 2004 Chevrolet Malibu with a 2.2 liter ECOTEC Engine. Hope this DIY was helpful!

first thing check make sure oil pan drain plug tight. check make sure oil filter tight. try tighten oil filter by hand see if turn tighten oil filter clockwise direcction if all is good. how many miles on vechicle.could have oil leaks park vechicle in spot that clean.move vechicle see if you see oil spots on ground if yes.your front timing cover seal leaking oil or rear main oil seal ;eaking.or valve cover gaskets leaking.if find no oil leaks more likely engine burning oil.replace pcv valve.check air filter if you see oil in air filter housing either have bad pcv valve or pcv not getting vacuum make sure pcv valve getting vacuum when engine running vacuum should be felt at pcv if not pcv valve bad or pcv hose disconnected broken or plugged.if pcv valve okay engine has worn piston rings.worn valve seals or guides or oil return holes stopped up thats all possible reasons for engine burning oil.if spark plugs oil fouled engine burning oil.

Almost all PCV Valves, have been on one valve cover or the other, for
the last 50 years

They never need replacement.

Remove & clean, if you got nothing else to do

Symptoms of a bad EGR valve are usually stumbling idle or the engine stalling when the car is warm (normal operating temperature). Find the EGR valve and locate the vacuum line attached to it. Start the engine cold and wait for it to warm up. When the engine starts to stumble, pull off the vacuum line. If the EGR is bad, the engine idle will stabilize and no longer stumble.

The pcv valve is usually located on one of the valve covers look for the larger vacuum hose coming from the intake manifold and follow it you should find it that way. changing it is a matter of sometimes using a pair of pliers to remove a small clamp then rotate back and forth the pcv valve while holding the hose and pulling it away and off.
