PCV Valve Replacement

[mfeisen]

Performed an advanced search on this forum, but didn't find much on this subject. According to the owner's manual, the PCV valve should be replaced every 30K miles. My 2019 Sportback 2.0T is nearing 30K and I'm not seeing the PCV valve. One posting alluded to the fact that there are two, one in the front and the other in the rear of the engine. The GM Part # is supposedly 2655189. Would greatly appreciate it if anyone could verify the part#, the number of valves needed, and their location under the hood. Also, is the Lisle 39400 angled disconnect tool set needed to remove the valve(s)?

The manual available at the My Buick site seems to make no mention of a pcv valve.

No PCV maintenance interval in mentioned in my owners manual either.

But how to replace looks to be in the downloadable service manual. Page 4695

Here is a downloadable service manual for the 2018-2020 Buick Regal. It is nearly 10,000 jumbled pages and most of the links within the document are broken, which makes it difficult to navigate. Stuff isn't too hard to find with some mindful searches though.

Credit goes to @stooge, who originally shared it on the Commodore Forum.
