Question about 1998 Chevrolet Cavalier

I cannot find the air/oil separator on my 1998 Chevy Cavalier

I cannot find the air/oil seperator in my 1998 Chevy Cavalier. My Haynes manual instructs to take valve cover off and there it would be but I did that and did not see it. I don't even know what one looks like.

We have 1998 chevy cavalier and is burning a lot of oil, per 1000 miles we ad 1 litar of oil., we did check for pcv valve but looks like this vehicle does not have pvc valve that we caqn check , can you...

If Pcv valve is not working correctly car will run real bad starving for air. And check engine lite will come on. I would add one liter of Locus oil stabalizer and drive it, Sounds like it's about time for a overhaul. best of luck to you.

Where do i find the pcv valve on a 97 sunfire

The PCV (Positive Cranckase Ventilation valve) is going to be on the valve cover. Usually has a rubber hose about 5/8 coning off it and running to the intake.

This is for the 2.2L OHV engine 1997 and earlier... according to Haynes, the 1998 & later 2.2L OHV engines "have an oil/air seperator inside the valve rocker arm cover that requires no maintenance. 2.3L and 2.4L OHC engines are equipped with an oil/air seperator that is attached to the side of the block above the oil filter."

As you are standing in front of the car facing the engine, if you look down at the top of the engine it is in the back lefthand corner of the valve cover. You will see a weird looking 1-1 1/4 inch star shaped nut on a round thing that sort of slopes up out of and toward the back of the engine & has about a 4" tube sticking out of it connecting to the fuel injector? assembly. If it is on too tight to loosen with by hand use a channel locks pliers to loosen it. Then pull the tube out & the pcv valve will be inserted into the end of the tube. Simply replace & hand tighten the nut.

Hope helped (remember comment and rated this).

2002 chevy cavalier turns off while driving

I fix my own 1998 cavalier. before I had the same problem. mechanics made me changed catalyte converter, combustion gaskets, EGR, fuel injectors with a tune up on spark plugs and boots... BUT the problem was still there. they all gave up and told me to trash the dang thing but I kept it. did research and studies, lots. finally found out the car was design without a regular pcv valve. **There is a thing called an air/oil separator on it. Its mounted on the block of the engine just right above of the oil filter. You must clean out the tubes. The one that usually gets clogged by oil slug would be the one connected to the oil. runs smooth like a baby after you get that clean. hope this helps.

My 1998 cavalier z24

it take water to make the gage work . if it a head problem i would do a compression check it should be around 125 or 150 psi if a cyclinder do not read then there your problem with the head if not a head problem and compression look good and u did not run for a long time . then the head might be ok then i would change the water pump and it should be good
