This.That amount of metal isn't normal for any enginewith 50k on it.

So the engine was out in January, and now in end of September it’s only accrued 4,000 miles? this is the first oil change since all this work?
Maybe a short OCI is in order, but all that metal, methinks something is wrong. I’m guessing valvetrain, maybe no oil is making its way upstairs. I wonder if the cams are grinding themselves away. Not sure how the valvetrain is oiled but if the head gasket was replaced, perhaps they blocked off feed somehow.
What kind of warranty was given for this work?
which doesn't explain the first failure.. this is the second..It’s likely that poor workmanship practices were used allowing fine abrasives into the engine/oil and it causes some issues. I would do one more short OCI and re evaluate. If it continues to shed metal, take it up with the dealership or trade it in it if they won’t help you.

FWIW this post is an example of why engine work is a loser for most mechanics and why they dont want to do it..
You mean the first failure of a leaking front cover from the factory which is somewhat common? The cylinder head removal job which is the one that can cause the most dirt or abrasive intrusion
OP does not mention if oil change was complete through any of these repairs, by himself or the dealership. From what OP indicated there was no evidence of large amounts of metal prior to these repairs.
here is what we know... QUOTE" Our SUV ( 2019 Highlander with the V6 2GR-FKS at 50 000 miles) had the engine taken out by local Toyota dealership to fix a leaking timing cover, ( 2end time this was repaired )"... QUOTE.
so do we blame the mechanic or do we wonder if Toyota built one of those babies that doesn't live a long life? I have no idea how common a front timing cover repair is on a Toyota..
no he doesn't. so anything on this end is speculation..This particular engine is somewhat common. The OP did not state how apart these repairs were.
Wearcheck gets the UOA done in a couple days.Blackstone takes almost a month as of today to do returns, but Napa took barely a week for me.
All good info thanks.OP, the "head tech" is 100% wrong on the head gasket material, it is steel. Again plenty of opportunity for steel shavings after removing BOTH heads, the chains, camshafts, and a "jr tech" not torquing things back where they were supposed to be.
Another 3k run and a UOA would be very smart at this point. Blackstone takes almost a month as of today to do returns, but Napa took barely a week for me.
@KrisZ I had seen that video and paint close attention to it again today, AMD says the o ring are on the low pan oil pick-up, if they forget them the engine blows up 5-10 min after ! So not the case with mine.
For the next months I will make sure to do regular italian tune-up, making sure to Rev-up the 2GR-FKS more than I usually do. Everyone seems to think it will "grenade in short order" good we shall see.
