All that fabulous info in the pdf you created is beyond words. Thank you so much.  I have a question if you don't mind.... Here's my story/questions. It is regarding the PCV issue with these engines - which I think relates to the oil burning too in some way:My 2013 Verano (same 2.4 Ecotec, GDI engine) has 105k miles on it. Burns oil some.But the kicker is... since I got it 3 years ago with 88k miles, the stem/tube on the Air Cleaner Outlet Duct Part #13372201 (covers the throttle body too) that leads to the PCV Breather hose in the crankshaft/valve cover has been snapped off! The gap is small, I noticed it when I got home with the car, thought that was supposed to be like that. Actually I didn't even know what that hose was for.Didn't find out differently until recently when I saw a video of a 2015 Verano and it had a metal stem/tube on the Air Cleaner Outlet Duct that fit into the PCV breather hose. When I looked again at my car, closer this time, I could barely see the stem in the hardened hose. Ordered a new Air Cleaner Outlet Duct not knowing that it had not been updated and it's plastic soldered connecting the 2 plastic parts!! Not happy. So I haven't had an operating (clogged or not) PCV system for the entire time I've owned the car and who knows how long ago it broke. I love this car, so I hope it's not ruined.Looking at your incredible pdf resource, "GM 2.4L ECOTEC Positive Crankcase Ventilation (PCV) System" - thank you so much for making it!! You mention you can pour cleaner down the center opening of the crankcase (is that what it's called?) camshaft?... on the image I attached, did I circle the correct location for the "center opening"? Can you also spray a cleaner in there? Like CRC's GDI Intake and valve cleaner or throttle body cleaner? Or what kind of cleaner would you pour in there? For my Verano the intake manifold kit with all the fixin's is only $100 from the dealer (I get a discount) so should I find someone to help me with replacing that, I'm all for it, but in the meantime, I want to get the PCV system somewhat operational again, because I am replacing the timing chain this week or next. I'd planned to do it preventively now anyway, but I think it's started rattling so it's going in asap. I don't want the new timing tensioners, etc. to incur damage right off the bat because the PCV system isn't working well enough. I did put a pressure release oil cap on, for what that's worth. I don't have any known oil leaks.I did have some oily water, just a tiny bit in my breather hose, maybe that's been working a little. No clue.My last question is.... would a new valve cover help anything? I can change that out myself, the gasket isn't leaking now, but will wear eventually, so I don't mind. If those baffles get nasty and are nasty, it's easier for me to get a $100 valve cover than take this one apart and try to clean all that stuff. Let me know what you think. I love this little car.Thank you to all of you![ATTACH=full]1942[/ATTACH] Thanks!</blockquote>
