Where is the pcv valve located on a 2001 isuzu rodeo 2.2l 4 cyl


My guess, a USA car?
and is not 2.2L diesel guess 2.
its the 2.2L gas engine and is really GM/Holden.
we in USA do have 2.2L eng. gas, with DOHC belt drive cam.
Ok, my guess 3 is that you just heard someone say replace the PCV valve. but that person never saw your engine before, so was a generic , wish...
If you try to buy the part, you will fail.
(aftermarket of course)

OR did you fail to say engine leaks oil bad
and that PCV can cause this, it sure can.
its a system not a single valve. ever.

a word to wise some engines have no valve, Like old jeep 4.0 liter gas.

some have only an orifice, (that needs cleaned only or not... inspection work best)
so next i google for it, and get ZERO.
I then login to mitchells for you (so can you)
and I SEE NO VALVE.
Know where there,(deep searches) shows PCV valve.


why is that?
answer is: IT is not there.
it uses some kind of special venting system.
in most cases its and orifice, fitting on the intake.

just posted this last week, my guess to you as anony. post2.

the above red line, may have pcv device here, orifice ,etc.
26105704-j1tz12pcffy4oogy4uqrcbj4-4-1.jpgsee this red arrow i think this is the vacuum port for PCV
clean that? is probably just and orifice fitting;
for sure it has:
1: a fresh air path to air cleaner.
2: and a vacuum suck side, with no valve.
on some engines its a Isuzu only section of pipe that if clogged, you clean it or replace the whole thing (very hard to source here)


here are all 2.2l , fix engines or buy parts
its best to know , what is there. (i dont)
quote:
2.2 L X22SE I4 (gasoline)
2.2 L Z22XE I4 (gasoline)
2.2 L X22DTH I4 (diesel)
"The 2.2 L engine was a derivative of the GM Family II engine introduced in 1995 built by Holden in Australia that saw usage first in Australian and European versions of Isuzu-derived trucks and SUVs, and was later used in the Isuzu Rodeo
unquote:
found this post on a real isuzu form
quote
no PCV valve as such on the engine, but there is a small restrictor on the inlet manifold gaskets - between ports 2 and 3.

How do you replace a PCV Valve for a 2005 Cavalier?


It does not have a PCV valve. Do a web search for this problem or look up in a parts supplier computer or buy a service manual and you will find out how the system works without a pcv valve.

Excessive pressure in the crankcase of a mazda 2005 6


Have you checked the hose from the valve cover to the air cleaner ?
The PCV valve pulls air from the crankcase into the intake, but the crankcase has to get fresh air from the air cleaner too.
If the crankcase is getting extra pressure from the cylinders you should have a check engine light and trouble codes.

Is the pcv valve replaceable in the 2001 Sunfire 2.2L engine or is it built in to the valve cover


Yes the PCV can be replaced. It seals into a rubber grommet in the valve cover. See pitcure of valve below.

Location of pcv on 3.3 dodge caravan


Look for a large rubber tube attached to the manifold port located on the top left side (passenger) rising up and and then curving down to the rear valve cover pcv port. It is a squeeze, but work the hose off the pcv port, and "voila" the pcv valve is INSIDE the port. Pull it out with its attached grommet. Do not attempt to clean. Replace, only, and save the receipt for the engine warranty. This engine can burn oil if it is a valve seal or manifold plenum problem.

Low on engine oil


Well, if there are no leaks, then it has to be piston rings or valve seals. If it's only burning a quart every 1500 miles, you would barely see any smoke, and by the standards of 20 or 30 years ago, that was normal.
