2013 rocker spitting issue has been discussed many many times. Subaru has addressed this with revised part numbers. If i recall 2014+ got slightly longer valves and revised rockers so pins stopped popping.

Not much to discuss here or bicker about.
@celek is motor god, im sure he can shed more light.

It was actually in 2013 it was revised but 2014 models, and I bet that 2014+ models spit rockers too
They also went away from 2 separate rocker part numbers between intake and exhaust

I know this is an old thread but id like to say i got a 2017 86 with 6k miles on it and the same thing happend while at idle, car was bone stock with no mods at all, i was almost done a cross country drive when it happend. Had a month long battle with toyota to clarify if it was under warranty because they told me it was from "engine neglect" because i had driven 4k miles in the last 5 days before it happend.

There was another thread that is currently active where this happened to someone 2 days out of warranty and Toyota was trying to claim he over revved. He pushed them for weeks and they finally concluded that it wasn't an overrev and said they would fix it.

Seems like Toyota finds anything they can to reject claims. So the 86 has weekly mileage quota now? Give me a break.

Good luck!

Do you know if the pin walked out, or was it something else?

It doesn't take much knowledge to fix cars as it's mostly just take off part and put it back in, it's the diagnosing part that takes skill.
I grew tired of fixing things on my work van recently and took it to a shop to find an issue. $2500 and many parts later they finally
figured it out. Of course they broke some parts on the way there that were good when I started and also lost a trans. dust cover but
it's running now so I can't complain, right?

Both take knowledge but whatever. I think what is happening with the 86 is Toyota sells so few of them that they aren't familiar with the common failures and make assumptions based on what would normally cause a rocker to fail which would be an over rev which would float valves. They jump on the first excuse they can to deny a claim rather than dig through TSBs or call corporate to see if there is and history of failed rockers. My understanding is the newer cars have new pivots (with smaller oil hole) and longer valves which changes the angle of the rocker but the design of the pin on the rocker (which is apparently what fails) hasn't changed.

Right! Now you have your problem fixed, you have several new parts and you didn't have to buy a new van - so, YES, be a
