yup. well documented that there is a cold start tick, it goes away in 15 seconds or so. Personally, I am not inclined to let a tech start digging around looking for it. I can see that becoming a rabbit hole in a hurry....
So.... other places are referencing a loose PCV to be the culprit. This is located under the engine cover, and under another foam/rubber isolator. Tighten that and you are good.
this is long and last 10 min or more, but is very faint or gone if I shut it down and restart it it does not have a set pattern. just wondering, I believe it is an electronically controlled noise and is normal but not a 100% sure
