i have just purchased a 04 cav amd speeking to the previous owner he said 1 qt every 1000 miles and that seems correct since i have put in about 1/2 qt in and i have ran it about 800 miles. he said it has done this for 4 years and never got any worse. Could this be the pcv systen and how do i fix it?
horsepower is how hard you hit the wall, Torque is how far you push the wall with you
Although your seems a little high our motors do tend to use a bit of oil.
listen ay no engine should use 1qt every 1000 miles unless its my dads 66 impala..pcv system uhh no fool. check them valve guides oil control rings OIL PAN GASKET...good luck homie.
^^ Have you read the forums at all about the eco motor?
Everyone here with an eco has had a range of using a quart of oil over 1000 miles to a quart over 3000 miles. My eco uses a quart over about 2500 miles to 3000 using synthetic. Using conventional, it's a little more, about a quart every 1500-2000 miles.
GM put out a bulletin saying this was normal. There has been some question among active users wondering if this is really normal or not, but so far the oil usage has yet to cause any major problems. The going consensus is just stay on top of the oil level (which reminds me, I need to check mine).
And yes, it is the PCV on these engines. The PCV is built into the valve cover. It is not serviceable, and it loops back into the intake system. If the original poster takes off the intake elbow at the TB, I'm betting the it will be fairly dark and in need of cleaning. Mine did. Most of the oil put through the PCV ends up at the bottom of the intake manifold, or in the TB elbow.
To the OP, yes, the oil usage seems a little high, but not out of limits. Keep an eye on it. Make sure it stays full. If you start using more oil, then start looking for a problem. Otherwise, you're probably ok.
Per GM, 1 quart every 5,000 miles is normal for the ecotec.
1 quart per every 3,000 miles is normal for a higher mileage motor. No idea what GM thinks is higher mileage....

Haha higher mileage. I'm gonna go ahead and assume that means out of warranty mileage. I've got 120k. My oil usage hasn't changed from 89k when I bought her till now. I'm not going to worry about it.

well so sorry homie, god dawg no i havent been reading because its hard i didnt pass in school ay...why cant you by pass that puto pvc system plug the vacuum side! by pass it dawg! but pass emissons first! then do it! @!#$ the state air quality and enviralment or watever ay keep your pocket fat with money $$$ plug at valve cover and intake!
Knock on wood, neither one of my ecos is burning oil yet (though the 03 with 92k now is burning a little off the top, but has not shown a drop on the stick)
Waiting to see if it happens here....

i have a really slow rear main seal leak i think...i have a few drips every day when i park. but i have noticed i go through about a quart at least by every change. im at 198.5k miles.
i also get a lot of blow by in my catch can of a fuel-oil smelling substance.
but it seems pretty normal to me, especially after a hard day of country cruising being really hard on the car pushing its limits...it'll even 'tick' like its low on oil, but it only does it for a short time. im wondering if thats a viscosity issue while its under extreme heated conditions and as the oil cools the tick goes away.

Maybe go back to school before handing out your expert auto advice.
Have a nice day.

You shouldn't plug the PCV. PCV stands for Positive Crankcase Ventilation. Meaning, when your engine builds up pressure inside that shouldn't be there (like, inside the oil pan, or above the valves) the PCV valve opens only one way to allow that excess pressure to escape.
Blocking this is kind of a no-no. For diagnosing purposes, sometimes the PCV will be blocked, however, you should NOT drive your car for an extended period of time with the PCV blocked off. In fact you shouldn't drive it at all like that.
I would advise you to take some time (even if it is hard) and read the stickies at the top of each of the forums. Or at least read the ones in this maintenance section. There is a lot of information here.
lol the way he's talking..im not thinking he's even serious.
unfortunately social media is the new eduation for the current generation...and i fear the direction this country is heading. screw auto modifications anymore, im saving up for a log cabin build in the Colorado mountains living off deer meat and moonshine..whos with me? lol
sorry OP..now back to you

Dude, I'd say the same thing, but if his profile is correct, he's 2 years younger than myself.
Also, I'll join you in colorado.
So it looks like this little sucker took off. Haha. Well from what I read it seems I'm high but not too high.
I'm going to change the oil this weekend should I try any sea foam? Put some in the oil and run it before I change it? Think that will help at all?

I had a lil bit of an oil consumption prob in my 1998 trans am. The prob was it was sucking so much oil from the valve covers that oil was all over my throttle body map intake etc. I solved this by adding a breather can to the atmosphere and plugging the tb port off.
Ive heard mixed reviews on Seafoam. I know it'll clear you out..but what long term damage it may do I dont know.
Ron if you're getting excessive blow by from your PCV port, you can just get a basic/good catch can, baffle it or buy a baffled one, then run it to a checkvalve and into your intake to recycle the spent gases (without getting oil contaiments into the intake). My PCV port with just a breather venting to atmosphere after i boosted, had liquidy oil/fuel crap all over my valve cover, down into my injector cups and onto the manifold. It was a mess.

More personal feeling than scientific data but nothing goes in my crank case but oil. I've heard plenty of good things about seafoam but I'd only ever run it in my fuel. And on that note now that I'm S/C and the 93 points of octane is kind of important, I probably won't even do that. I'm with blu on this one. Almost every system can benefit from a baffled catch can and check valve setup, especially the ecos. Whatever you do don't vent to atmosphere, ecos need that vacuum from the intake for the pcv system to work properly.
