Engine rattle, spun bearing? Now wont start
 

I have a 2013 FRS with 60K miles on it, no mods, OFT tune only. Today driving home I was doing some spirited driving got the RPMS up but not for long and afterwards my car started to make a rattling noise. I didnt think too much of it, thought maybe a bolt came loose on some trim. So I drove it trying to get home maybe 5 miles or less, the rattling seemed to not get worse but I started noticing some power loss on acceleration. Then I came to a stop sign and the engine cut off, with the whole dash lighting up. Haven't been able to start the car since, the engine cranks but wont start. The error codes i got were P000A,P000B,P000C,P00D,P1603,P1604

Any thoughts? Help? I was researching and it sounded similar to a spun bearing/rod knock. Is it possible to happen that quick? Will the car not start at all if the bearing spun? I didn't have any prior noises or issues

Yes sounds like it

The first 4 codes are all cam position related so could be a sensor but a spun bearing could also trigger those codes.
The last two codes are starting issues so could be anything.

Was the engine running rough before it cut off?

Not really, was just making a bad rattling or tapping sound that seemed to increase with the Rpm. Might have been a little sluggish/hesitant on acceleration but nothing drastic

Sounds like a valve issue

Mine lost power before the rockers came out. Wasn't misfiring at first.

I uploaded some photos of the oil, oil pan, and pickup. Lots of small metal flakes nothing large except for silicone in the pickup. Is this pretty normal or another sign of failure? Im going to remove the timing cover tomorrow see if anything in there looks broken

New motor comin up.

Did have the recall done?

No recall done, didn't need it according to Toyota. Said that it was a late 2013 model and valve spring issue was resolved by then

All that silicone on the factory motor, wow. Think I've seen a failure thread from a late '13-early '14 model, spun rod probably from the broken-off gasket material. Might have been a bad run on some of these motors.

Really seems like a greater failure point than any other thing on these engines (besides spitting rockers out) and surprised Toyota doesn't recognize it and start pulling engines.

There were at least 20 failures just like that well before the recall ever happened. They sort of got overshadowed by the recall and people either never heard of them or forgot. Most were very early ones but a couple of others were later 13s. Think there was only one 14+ though.
Unfortunately there is no such thing as the "perfect" manufacturing process and my guess is that the robot that initially applied the sealant screwed up just as bad as some of the techs did later.

They had to have known about it but odds are it was easier (cheaper) for them to just let the few that may have had the issue through the system.

During your spirited driving did you happen to do a long curve? The majority of the per recall failures happened shortly after the driver entered a highway from a curving ramp. My theory was always that it was a combination of the silicone and the prolonged turn.

Bet you a beer it is your number 4 rod bearing. It was almost always the number 4 rod bearing.

Nope just nice stretch of freeway no curves. I kinda had some access to rod 1 and 4 with the oil pan off didn't notice any play I'll have to give it another look.
