Just an update on my car I dropped it off they called me two days later and said it’s done. They said it was my pcv assembly causing the tick but I’m very skeptical. I just don’t understand how that would cause it.
so i have something similar. i have a 2017 GT cat delete CAI and tune and i just got this back from the dealer and it started doing this but it only does this if the ac is on or under a small load
