2020 Nissan Pathfinder 3.5 PCV Valve Replacement - Easy

[@DrDaddy-yg2ki]

Ever thought about installing a catchcan while you're in there to combat the carbon build up on the valves from the DI? I can't find anyone who has done it or anyone who needed the valves cleaned because they didn't do it. If got 60,000 miles on my 17 and don't want to spray clean it for fear of chipping some off in the combustion chamber, but.... can't find any info on a catchcan either
