Hey peoples, I have the 2008 CTS 3.6L DI with 60K miles that runs beautifully (for now) but I here there is a lot of PCV breather issues and oil consumption carbon problems on this particular motor, is there anyone out there that has done the PCV breather modification with a so called catchcan?. Any advice for preventative measures on all this would be appreciated as I plan to keep this car till the wheels fall off...Thank you :-)
I have 137,000 miles on my Deville but I have put in about 5 quarts of oil since last oil change but see no leaks on the driveway. I can smell oil but hard to see where it could be coming from and the antifreeze leak is slow but when i took it to my local GM dealer they said they put it on a pressure test and could not find a leak. I am frustrated because I drive alot of miles and I am actually afraid to go out of town with the car with these issues going on. Any ideas as to what to check for and estimated cost would be appreciated as money is really tight for me.
