I'm having a problem that I can't seem to get a lot of information for.
I have a 2012 CC Sport with 114k miles on the clock. I have all service records and can confirm this car has been taken care of--correct oil, etc., etc. I've owned the car since it had 78k on the clock. When I got it, I was going through maybe .75 quarts between oil changes (5k intervals), so pretty normal.
But the oil consumption has gotten worse. Now, it burns a quart every 500 miles. No leaks. Compression was right around 150psi when I checked it, so on the low side. Scanned with VCDS, no codes. Checked the turbo, no play in the actuator (correct term?) shaft going into the turbo. Highly doubt it's the turbo really, car pulls strong all the way up to redline with no whistling noises or anything else indicative of a bad turbo. PCV has also been replaced. Sometimes I get smoke on hard acceleration.
Now, I've found a few posts across the Internet about bad piston rings on certain 2.0T engines, but not a lot. Has anyone had experience with this issue before? Would it mean a new engine, or could I get away with a partial teardown to just replace rings? Has anyone heard of VW addressing this problem? Doubt I could get them to help, given my mileage, but would still be nice to know.
I've also been recommended to switch to a thicker oil to see if that helps. I'm currently running Mobil1 0w40, but there don't seem to be a lot of options out there for something like 0w50 or 10w50. Recommendations?
And finally...should I still be driving this car? I know oil consumption=clogged catalytic converter for sure, but given the rate of consumption...just doesn't feel like I should be driving it 'till I have a plan of action to fix. I just rebuilt the engine in my '72 Super Beetle so I've been dailying that while I figure out what to do with the CC.
Any help/points in the right direction is greatly appreciated! Thanks for reading
