That Mustang had 82,000 miles on it and he put another 3,000 miles on it before the rod bearing ate itself. Who knows how that engine was treated for 85,000 miles. Not relevant here IMO.

I did see this though in Post #6 of that thread, and found it interesting because it's been theorized here on this board that the BBQ Tick could be excessive rod side-to-side clearance.

"Something to note though, I think I have the BBQ igniter tick that people have complained about. It's completely random, one (low) volume, and doesn't increase with rpm. I think I know what it is though. I noticed that our rods can slide back and forth on the crankshaft after being run for a while. When I installed the new bearing and tightened the old good one they didn't move side to side at all."

Thread where a lot of rod side-to-side clearance is discussed.

There is supposed to be some rod side clearance, but if it's out of spec it could be the source of the random BBQ tick.
The BBQ tick does increase and follow RPM. If something was moving side to side because of a little play there would not be metal shavings in my oil and other peoples oil.

The other thing that bothers me is the dealer is replacing short blocks only, if metal has gone through the motor it's in all the oil passages for the cylinders heads and related parts. I highly doubt that they take the time necessary to flush out everything properly before re assembly, hence an entire new long block should be standard issue. If any metal is left behind it will wipe out the cams and cause further issues down the road.

I agree with that, I guess not everyone has had metal in their oil or they dont know if there is any, I had this tick for roughly 2500 miles and first time I'm seeing metal is now. If the tick went away after engine was warm and didn't follow rpm I would be worried about it. I'm going to wait and see what they tell me and ask about if there not flushing it I want a new long block.

Obviously there are more than one thing that can make an engine noisy - loose rod or main bearings, excessive piston clearance, too much rod side clearance, too much crank end play, bad lifter(s), broken valve spring, faulty cam chain tensioner, etc.. Some of those problems will put metal in the oil, some of them won't. The BBQ tick certainly is random while at idle. If it was a constant perfectly timed ticking with RPM, then it's something else.

Holy shit I just checked my catch can with a flashlight and wow... :

This is not good. Car is at the dealer, I took the can off before bringing it there so they couldnt try to blame it somehow.. Looked at the can oil after I got back.. I wonder if I should have left it on.

This is with only 700 miles on the oil. I changed out the break in oil at 1175 miles this was at 1850. Drained the can like at like 1600 miles few days ago too but didnt check for metal.

My eyes are bad.....
Did you clean your catch can before install?
So the the pv vapors carry the metal particulate?
Did you Take a magnet to the stuff you saw?

If you search about "glitter" or metal in catch cans you may find it's pretty common (often said to be from the filter element in the can). Allot of responses also seem to say it's difficult for metal to come through the PVC system, so unlikely.... I did allot of reading after seeing the sparkly badness first hand...I'm not the expert but if the internet in general is to believed this isn't the same thing as seeing it in your oil filter or oil drained from the oil pan.

Yea I even vacuumed the catch can before install, and I had drained it multiple times before this. I had an oil change too 700 miles before this so its not the original break in oil. Its castrol edge extended performance which says it contains liquid titanium but i dont think that would be some visible glitter...)

I just checked if the flakes seem to be magnetic and they didnt seem to be magnetic, they look kind of like brass or maybe worn cylinder liner... idk

If it was cylinder liner, I do believe that plasma arc liner is magnetic. However, it is commonly known among Navy Engineers (like myself), that metallic yet non-magnetic particles are almost ALWAYS going to be a babbit/antimony type of alloy....ie. BEARING material.

I could be wrong though.

You probably are very correct
Would the vapors can carry metal particulate? Just curious

That also seems like another real head-scratcher. Unless air flow through that catch-can was like a hurricane, I just don't see how free flowing vapor would carry that many particles. It just seems odd.

But hey, the particles are there, so what the heck do I know?

Well, those flakes were definitely not in the can or can filter media when I installed it. When I drain the can though I just dump it into a jar I dont actually wash the can so, that metal may be from all 1900 miles on my car including break in. Still seems way excessive and concerning.

Yeah, seems hard to believe that particles of that size would get into the catch-can by the PCV system ... but maybe they are smaller than they seem and can get carried in the oil vapors.

Cutting open the oil filter for inspection is the best test to look for abnormal debris from an engine getting damaged.

Nonsense.That is not from the can being made.

I had used and dumped oil out of mine about 4-5 times before metal showed up.. There is no metal particles or shavings in these cans.

Had 4-5 good runs of oil dumped out over 2-3 k miles before I started seeing metal in mine, its not from the can being made.
