Another GR86 blown and warranty denied

That is beating on it? I should have blown up every car I own years ago. There was nothing particularly fast about that car and it certainly was not being run hard at all, at least to me.

I grenaded the 10 bolt in my 98 Z28 running a dial in of 11.90. Had it towed to dealer with the numbers on it and rubber all over the wheel wells fully expecting to pay full price for replacement. Service manager "11.90, that is pretty decent we have not seen a lot of LS1s in here yet with modifications like that. " Me "How much will this cost?" Service Manager "You are still in factory warranty"
0 dollars, now every F-body I own has a Ford 9 inch.

Small what do you consider to be big? C7 and 6th Gen Camaros with 6 piston Calipers have 370mm two piece front rotors and equally large pads they are not small.

At stock, it's not that they're small per se, it's that they're small for the huge amount of power and super wide tires the car has, so constantly braking at the high speeds a 5/6/700hp vette can easily get to will quickly tax the stock system. Intermediate folks who run 200tw tires may get away with it at first but should look towards a better solution as they get faster.

I don't know why the kid didn't call in the zone rep. Not some faceless dolt on the phone. And you want to be there for the engine teardown and photograph and log everything. Hope his State allows arbitration. But it's looking more like Lawyer-up, time, unfortunately.

I sued a Porsche dealer in Lawrence, Massachusetts in the 70's for a nasty used Audi they sold me. Went all the way to court day, but they caved and settled about a 1/2 hour before. Got full purchase price refunded and got to keep the broken car. - But things went awry not long after that. Must have been some blame and some fault and then bad karma on my end - Ken
 
He notes no mods in the description of the video - intake/exhaust aren't going to be in play here unless the dealer/Toyota is an absolute stickler...I'm quite sure TRD sells the same type of mods which are warranty-kosher. Based on teh fact he even mentioned the track use or showed this video to Toyota indicates that he likely isn't hiding anything (who does that?).

Spend 5 minutes Googling "GR86 oil starvation". Huge posts on the 86 forums about it, on the main car sites, etc.

I agree with your last statement but if you can't drive like he did on the stock setup, that's an issue that would present itself more regularly on the street. I do some mountain cruises with folks in the same car that push harder than that. The most likely speculative scenario is the RTV blocking the oil pickup here, not BITOG 20W boogieman (I mean now even 30W isn't enough for driving harder than a grandma on BITOG?...good lord), driver, mods, etc.

Yea like previously mentioned, the oil pan and pickup tube is not designed for this kind (track events) of use. We don't know how many times he had done track days in the past. Might have been doing the damage over a period of time before the engine said "I'm out!" Car wasn't run that hard in the video; heck I've done worse in my truck! Yes, there's the RTV thing here, but also go to remember the design flaw in the oil pan. This has been an issue for years, you would think Subaru would get it together. But, I guess if it works for 99.5% of users, then why change? I can tell you I'm not tracking our Outback; it's slow as balls :ROFLMAO:

Ok so there is something else that can cause oil starvation...interesting.

Apparently under hard acceleration/cornering it can starve the engine for oil. They make kits with a new pickup tube and some baffles to eliminate this issue. I do not know if it's still an issue now adays, but looking at that video it kind of gave me a clue of it still is. I may be talking out my rear-end on this, but I know it has been an issue in the past.

That's true of a lot of cars though, hence why dry sumps exist. There are many cars out there where you should really track them with an extra quart in the sump.

Seems like a possible issue...man...he just wasn't on it that hard in the video...

Unless you are pulling big G's on r-comps....a set of summers or 200s shouldn't cause this issue. I have gotten what we call in the VW/MK7 world "smoke screen" form surge through the PCV system. I upgraded to a different OE PCV which seems to have sorted it but a catch can + upgraded PCV plate would be best. Some folks with r-comps/really hard cornering g's have toasted the VW engines in that manner (oil starvation) which is only remedied by a baffled oil pan.

Likewise in the 3rd gen Tacoma's with the 3.5L V6 if you're going up a steep incline (offroading, not like mountain driving) they've been known to starve for oil as well. Different application, same problem. Toyota obviously declines warranty on this as well, despite having a "TRD Offroad 4x4" sticker on the side of the bed.

Some Corvettes have this problem, some Porsches... Heck some Porsches have issues where they don't drain back to the sump fast enough. This isn't all that uncommon.
 
I've also never heard of a piston flying out because of oil starvation or running too light of an oil but there's a first for everything.
It means the piston rod big end bearing failed and seized on the crankshaft journal, which makes the rod snap, and that type of failure can "window" the engine case/block.

He kept driving to the point where the rod seized and put a hole in the block - that's the point in the video when the engine died and a bunch of smoke came out from under the hood. If he would have pulled off much sooner and shut the engine off, the engine might have been way less damaged.

Caused by what, besides the possible RTV issue? If a tear down finds no RTV on the oil pickup screen, or any filter media or RTV downstream blocking an oil passage, then what would be the cause?

This same type of issue happened last year if you do some searching. Same situation, RTV/oil starvation/blown motor during an AutoX event.
Is that the only one officially verified to be the cause? How many others have blown-up from this possible RTV issue? I'd think the GR86 and BRZ chat boards would be on fire with with reports and talk of dozens of blown-up engines if that was the case.
