For piece of mind I will most likely do what I always do with my performance cars

Get the oil filter back from the dealership after the oil change, open & inspect it

A messy job, much easier with the Supra than the GRY :)

Does not bode well, could be another factor with the delayed release of cars. This isn't a new problem with Subaru FA engines. Fortunately it would be covered in warranty but personally I wouldn't want the aggro and to be without a car for months (because it would be months in this day and age).

So it seems to be the same issue that caused lots of GT86 engines to fail after the recall - too much RTV sealant breaking off inside the engine and clogging the oil pickup, leading to oil starvation and therefore bearing failure. Only this time it's happening to cars out of the factory, and because of the same type of sealant on the sump pan?

Worrying. Why do they use this type of sealant rather than a more traditional one piece gasket? is it cheaper?

Sealant applied to components like this I'd have thought would be machine / robot applied - if so the risk would be to all engines built where a metric/tolerance is wrongly being applied?
I guess maybe by the time I get my GR86 this will have been resolved.
 
I imagine it's a fault with the curing time or quantity applied as opposed to position, if the matting surfaces are clamped whilst the sealant is too wet it will squirt out the sides, if there is too much applied then that's self explanatory.

Makes sense, given its been found in the early stages of EU prod then Im not too worried but does imply further delays likely. Also with up to 10 year warranty then it should all be resolved by Toyota if it happens in the next decade. Unlike M96/97 Porsche engines which have for years been failing for years especially when warranties have now long gone, this wouldnt stop me buying a new/used GR86.

Starting to trickle into the states now. This car had 5500miles before it spun a bearing...

Same cause, excessive RTV on the oil pan gasket breaking away and blocking the oil strainer.

I am now starting to think that this is the reason cars are on hold. Judging by the other markets (without language barriers), no cars are currently being delivered to customers.

If that is the case you would think Toyota would be doing a recall before they all go , pop, bang (or whatever sound they make) 🤔 Fixing any cars which have not been delivered also sounds like a good plan, even if that means a delay. 👍 Starting to think there may be a slight benefit from being a bit further down the delivery list 😉

Damn, that starts to make me worry. I check all GR86 related Twitter posts daily - mainly for photos and videos because I can not read the Japanese stuff but I can tell I have seen such photos a few times now. It seems that more and more owners check their engines now and unfortunately the outcome quite often looks like this:





I also found this report where the engine exploded but Toyota refuses the warranty because it happened on a race track. Quite interesting is their statement which says they are not aware of such problems - ohhh boy... ☹️

Translation of the interesting part:
Now, I thought I would take these events to a Toyota dealer for a check-up.

'The engine blew at the track, so it's not covered under warranty.'

I was told that...

What?

Because the dealer organises a circuit driving event.

Is that a trap to get rid of the warranty?

Cars that are not covered by the warranty are not taken up as recall cases.

Officially, Toyota has not yet received any reports of engine blowouts! This is the current state of affairs.

Ah~, GR86 engines are breaking down all over the world.

They're all running on the track, so they're out of warranty.

So, because it's out of warranty, it's not accepted and there are zero cases of engine blowouts.

If this continues not to be recognised I will be tempted to take my car to Toyota and get them to remove the sump and inspect it. If its clear and there are no issues I will pay for it, if there is an issue then that is warranty so they can cover the costs.

I had pretty much the same thought this morning. The big question is when should the check be done? I assume it will take some time before this problem shows up.

I was thinking within the first 1000 miles.

If the failure was due to silicone blocking the pick up then that's nothing to do with the track day so that'd be concerning. If it was oil starving either due to the oil being too hot or g forces then it's nothing new. Track days should be like mods, if it contributed then you're out of luck, if its unrelated then it should be covered
 
Here's your free NASA membership and a free trackday coupon to void your warranty!. 😐

Hopefully ToyotaUK is taking the stump off every car they currently have parked up, cleaning them and resealing.

I wouldn't worry too much about what happens in the US. Warranty is notoriously inconsistent and unfair over there, they were like it with the old car. Toyota GB seem to be alot more level headed about it.

This is why lots I hear from the states I take with a massive pinch of salt. I'm on the reddit group and it's mainly US owners and some of it is painful to read through. Lots go on about rev hang and removing the clutch delay valve which I've never felt the need to do on any car.
