Hi guys, My car has began to use some oil . Usually, the first 3k miles it used about 1/4 of a qart and then the next 1.5k miles it used 1/2 quart. I remember that on my previous car, the only thing I had to do is change the pcv and it worked but on the v6 3.6l on my 05 cts, where is it located please?

I'm still searching.. can someone post a picture and maybe circle the pcv location? Thanks.

No pcv on this engine. Its be replaced by 2 metering tube in the intake.

so it means no maintenance at all or can I just clean those tubes as a preventive maintenance?

No PCV as noted, no maintenance.
Keep track of oil usage and tell the dealer, you could have another problem.

Tell the dealer but at our dealer there some cts that drink some oil and nothing they can do cause they say that its not so bad and its on spec. :cookoo:

Thanks guys! I'll keep an eye on the oil consumption and tell the dealer about it.
