Good to see you still active just like 2014. if this continues I recon ppl gonna start a religion after you.


PS: I was right about never getting 1st year Subarussss, I'm gonna wait till model refresh this time cuz I still had to redo my timing chain cover due to leak on my 2015. *just dropping by cuz i saw it on the news.

I disagree with this...and until proven otherwise this entire "loose sealant blocked the oil screen" thought process.

On the new 2.4 engine, the pick up uses a 5 sided screenbox to ensure proper oil flow in case of a partial blockedge. You can see it in the pictures floating around...it's a box with sealant at the top, but the other 4 sides of passages are open and clean. Unlike the previous version pickup that had a circular screen at the bottom that could be completely clogged. The little bit of blockage shown, while not ideal, would not grenade an engine and would maintain proper oil pressure.

I'd bet there is something else "starving" the oil on the cars that have failed. Maybe oil not returning to the pan in high g loads, (ie; drifting, hard corners), maybe low factory oil fills, maybe faulty PVC systems, maybe faulty new oil pumps.......

Cavitation due to inlet blockage... you have to take into account mass flow rate, fluid velocity as the suction inlet shrinks, oil pump speed /rpm and a few other things. If you have a blockage the fluid velocity has to increase to maintain the same mass flow rate which lowers your pressure, look at bernoulli's law. Even if it's not completely blocked, at sustained high RPM with all those factors that's enough to give you enough starvation to spin your bearings.

There was a guy who tracked extensively /owned a shop in South America (Peru?) on this forum who was blowing 13-16 motors left and right until he went to a larger pickup tube. The thread should be on this site, he had some good data points.

And a host of oil leaks:
https://www.ft86club.com/forums/showthread.php?t=67454

These cars have never been bulletproof and it seems memory is short on the first gen issues that didn't really get cleaned up until 2015 or so. Even then you can still fuel/oil starve any FA20 FRZ86 unless you put some mods in, or break an axle. And I suspect those particular issues will persist in the 2nd gen because fixing those issues would add hundreds if not thousands to the sticker and 99% of these cars will be driven no harder then grandma's Prius while under warranty.

If you want to drive a sports car at 10/10ths and not have the manufacturer deny warranty claims I'd get a Porsche, Mazda, or BMW/Mini over anything else, and even then they still might tell you to go pound sand. (I know a guy who put 4 transmissions in his ND Miata, Mazda warrantied the first 2 or 3 iirc)

If I had a new car I'd be pulling the oil pan this weekend, cleaning out the tube and applying new sealant. I'd repeat at the next oil change and cross my fingers that's that and no more would break off the timing chain cover. This is one of the easiest to prevent issues this chassis has had and it's a one time fix.

*as my fucking 2nd TOB starts making noise at 115k miles*

Curious if more cases of blown motors starts popping up as more cars hit 10-15k on the odo. Has anyone found rtv in the filters?


Someone on the FB group checked their dipstick.

Is that RTV on the dipstick fully bonded on the tip? Or is it just sitting there?

Shared my buying experience, complained at the dealerships that sucked, and praised the dealership that got me the car.
Told them I saw the news on Road & Track and CarBuzz about people who got warranty denied after a track day, and got worried given that I'm offered a free NASA track day.
Told them they I like the car and appreciate that Toyota makes them, but that the dealership experience very negatively impacted how I see Toyota as a brand, and how my friends see it.

The guy on the phone listened and "took down every word and will escalate", apologized for the experience at the end, and overall acted like he cares. I felt like I was doing a confession for someone else's sins haha.

A note of warning: they asked for my full name and VIN number. I said I was driving (I was!) and didn't have the VIN handy. I wonder how many John Does are going to call them

Give them a call. A sudden influx of people all bringing up the same / similar topics will not hurt, and there's a slight chance Toyota is going to listen and change their stance. They put so much great effort into marketing the GR86 it would be a shame if another department(s) blow it up.

If you're busy and don't want to waste too much time, call them on the way to work.

I haven't had time to pull my own oil pan yet but something that's stood out to me as I see everyone's pictures - there appears to be very little surface area on the engine side of the mating surface. I've never worked on a Subaru engine but for other engines I've pulled pans on there would usually be about 3/4" of mating surface but some of these pictures look like they're only 1/2", if not less. I could be wrong though since it can be hard to tell scale in pictures without a banana. That narrow surface would make it super easy to over-apply.

I disassembled my filter today and there was nothing notable in there. 2 tiny metal shavings, a few tiny black particles, and a small piece of light green somethingorother.
