A PCV separator, which is unique to the LT4, was developed to keep oily air from being drawn through the intake, where it could end up collecting on the back of the intake valves. A little bit of oil on a port-injected engine can help lubricate valves, but because all Gen 5 V8s are direct injected, there’s no fuel washing the back of the intake valve. That means oil in the PCV system can end up sticking to the back of the hot intake valves impeding airflow and eventually preventing the valves from seating properly. |
GM designs their engines for 300K miles. I think there are allot of scare tactics in the forums sometimes to drive sales on things. I could care less if I have to do some cleaning at 50K miles or DI cleaning. This car doesn't drink oil like my CTS-V did so I am not concerned. Also my car has 4K miles on it and my throttle body was dry and didn't see any oil. My gen 2 CTSV would eat a quart every 1K miles and fill up my catch can before it was even time to change the oil. Just my 2 cents, if you are paranoid about it then just buy one, otherwise I wouldn't worry too much about it.
