Great job 👍

Change the air filter dude.

Does this pcv value may cause white smoke from the exhaust pipe ?

It will idle higher when first started and then it will settle back down once the ecm relearns

You can take that throttle body off and clean it better and replace the gasket also.

We have a 2008 cts with 374k miles on it. We got it from my mother in kaw when she bought herself a Subaru. I jusr put new hub bearing assemblies on the front, now i need to do the pcv system also, have oil in the hoses. Have to do front brake rotors and pads and struts and shocks. Spark plugs and clean the maf and throttle body and i think i have a bad o2 sensor and not bad catalytic converters, it doesnt smoke.

My 2008 cts has 314 thousand kms on the odometer
