  1. The dealership did finally get back to me on the teardown and it appears that the issue was a loose timing chain, which was causing it to scrape against the guides to create the noise I was hearing. The dealership hasn't formalized the list of replacement parts yet, but it sounds like it will be a timing chain, guides, and cam phasers at the very least. I am leery about the metal shavings in the oil pan though. I don't think a loose timing chain would be a direct cause of that. The dealership said the heads and valves look good and the chain didn't jump timing. But, I know that once a timing chain starts failing it can cause all sorts of bad things downstream. I was hoping this would be more catastrophic so that I could get a new long block and not have to worry about this down the road. I think I'll end up riding out the powertrain warranty in the end, and selling the car once that's up. I'm going to guess this is not going to be the end of the car's engine troubles if we've already had to crack open the heads and such at 3k miles.
  2. Sorry to bump an old thread, but I was searching around the internet to see if anyone else was having the same engine ticking/tapping/knocking noise that I'm currently experiencing with my 2020 2.0L SEL Edge. Sure enough, the video that mcsweeto posted is the exact same noise I'm hearing. It's definitely louder on a cold start and I hear it off and on when accelerating and coasting. I also have rough shifting in the lower gears (stumbling, hesitation, etc), which makes me suspect that it might be a cam phaser issue. I know Ford has some notorious problems with those on the 3.5 ecos. The car currently has just over 3k miles. Right now the car is sitting at the shop after the dealer service tech acknowledged that the cold start noise is not normal. They also pulled the oil and found metal shavings. So something is definitely not right with this engine. I'm currently waiting for the dealership to do the tear-down and find where the shavings are coming from. What was also odd, at least to me, was that the factory fill oil was green in tint. I understand this is a dye that they use to detect leaks. But I don't know if it's a standard practice to add that at factory or not. I might suggest those that are seeing this same issue check their oil and see if there is any metal shavings present. That was the definitive proof that something was wrong and the dealership did not fight me on the tear-down after that discovery.
