Toyota and Subaru know they have a massive problem. The tactics they’ve used to try and discredit to void warranties is an example of how big this issue really is.
Might be. But with no (zero) data available, can’t say for certain. now can we? What oil used? What are engine temps? Any engine mods? Surprised they can’t figure out the issue with a simple engine breakdown. Almost like it was human error?
@@michaeljohn1160 It's been a while since I thought about this. But it has bee proven without a doubt that the oil capacity for the stock system is not enough for racing. The large and sudden oil pressure drops is air.
It is both a design flaw and a production flaw. The engine failures are happening to plenty of cars that have never seen the track and have the correct amount of oil. And it is not rare. It is actually just a matter of time. You cannot build a motor with RTV floating around in the engine and pieces of it breaking off from the globs of it protruding out of the gasket surface into the engine and not have it eventually clog oil passageways. And the RTV is not just from the oil pan. It is used on the extra large timing chain cover and lots of other places that are on the other side of the oil pickup tube and thus the oil pickup tube cannot stop it from going into other parts of the engine. Plus, the oil pickup tube cannot stop small pieces from being sucked up into the oiling system from the oil pan (those screens only stop larger pieces which eventually get broken down into smaller and smaller pieces over time and miles). I would love to buy one of these cars, but I am not going to do it if they do not fix this problem. Scrap the robot that is putting the RTV on the gasket surfaces and go watch how other car manufacturers do it and copy them. Easy peasy.
@@jimihendrix8535 There are exactly ZERO cases of RTV failure. Sorry, you don't know what you are talking about. I am mildly concerned about RTV and will eventually drop the pan and clean it out. The entire issue is gravity with a flat engine, and high rpm right turns. I use my car as a daily driver, have a oil pressure gauge. After 50,000 miles trust me, there is NO issue in normal driving. If you race, you need either a larger oil pan or a system to add oil when needed. If you do high rpm donuts, you are going to blow it up. Don't do high rpm donuts or racing without a larger oil pan.
@@artblackwood7936 You are dead wrong. Most of the cases are RTV issues because they are not track related (engines blowing up driving down the road that have nothing to do with high g forces, etc.). It's great that you are not concerned, but that has nothing to do with the facts. Good luck with it. I actually think you are worried and just lying to yourself, but good luck with that. LOL
Currently there's accusumps which will deliver pressurized oil once it detects a pressure drop. Otherwise the aftermarket is still working on a baffled and extended capacity oil pan.
There isn't one other than completely disassembling the engine and correctly replacing the RTV as step 1. Most cars are not failing from the lack of baffle issue (other than possible tracked cars).
@@mcasuspension3976 did you give it to Toyota to check out? New model and all, engine failure is something that they are keen to look at, even if it was on track.
Yeah, the day German manufacturers, especially in the Stuttgart area, begin dabbling with flat engines, that spells the end of the vaunted engineering. /s The horizontally opposed cylinder design is old and mastered by the Germans. Subaru is just so bad at engine designing over the years that I don’t get how they get away with it.

There is clearly a design flaw in the oil holding/delivery system.

Damn, was planning to get myself a new 86/Brz to whip around QR like this...i think not now
what is the solution to this oil starvation problem? besides toyota doing a recall....

@@sl0907 Unfortunately that does not fix the RTV issue.

Is it RTV's issue?
Most likely oil starvation from high G corners. There seem to be some problems with the oil system keeping pressure in right hand turns.
No
could definitely contribute to it. anything getting sucked in / blocking the flow of oil would naturally damage the engine
Why do people just keep driving?
Did you tear it all down? And if so what have you found?
There was no clear indication of exactly what caused it so we can't say for certain what it was.
@@mcasuspension3976 did you give it to Toyota to check out? New model and all, engine failure is something that they are keen to look at, even if it was on track.
@@Blight-fp3vt no we didn't we just had a new engine put in at The 86 Shop. Since it wouldn't be under warranty we didn't contact Toyota.
@@mcasuspension3976 no worries. I guess they might ask to charge for the teardown, but to never know if they just want them to look at.
@@mcasuspension3976 Accusump time
Toyota didn't test this car for even one day lol
it's what makes a subaru a subaru!
Oh no,guess he didn't change his oil every 500 miles and baby it the whole time of owning it.
nothing new the boxer engines always failed from Subaru , the Germans dont use that crap design for a reason

Too common this is, Toyota lied they did.
To-Yoda
It's a Subaru with a Toyota name on it. Subaru engine-- not Toyota
its the notorious subaru boxer engine. what do you expect.
Dat toyota reliability
