Is there no way to run a scope down from the top of the oil system to look at that filter from the top side? Meaning not having to drop the pan?

1. If there is no blockage at that time, doesn't mean it can't develop later. 2. If you dropped the pan without observing problems and you do find some blockage, now what? Bearings could have been starved for a while but not enough yet to spin. Suby/Toyota is not going to replace your engine just because you "found" it. In this scenario, I rather let it blow and get a new engine. And no.1 still applies if you clean it up. 3. Any "unauthorized" work can lead to denial of claim later on. While I also thought about dropping the pan myself initially learning about this, after some thought, I would highly recommend against it. Just send it hard and hope it blows (or not).

His motor is fine for now however. One of the mods has put forth the theory that the QA hold earlier this year was to address this issue before cars made it to customers. I think someone had already mentioned that in this thread, but IMO it definitely could be the case. Last edited by DylanJZA; 07-31-2022 at 03:00 PM. |

If this asshole is a well known drifter then you should try to warn people in the community about him that he's essentially a narc. That should get him stigmatized.

Toyota buys the cars from Subaru. That means costs due to factory defects will go right back to Subaru. Toyota wont be out a penny.

Welp, you sure can't see much from underneath with the pan flange being so wide, but the one area I could feel seemed to have more squeeze out than I'm used to seeing in my line of work (which is quite different to automotive, so my opinion probably doesn't mean much on that). I do think that this is one of those times Id rather the sealant was weighted towards the outside than the inside. At least then the worst thing would be an oil leak, which I could catch...
I thought about bringing this up with my dealer to see if they want to take a preventative look at it. However, since my car is exclusively road driven (and not very aggressively), I think I'd be at a very low risk of failure, and I'm not sure what I'd hope to accomplish... I think @Petah78 makes a very good point. There isn't really a way to head this off. Just have to drive it, and let the chips fall where they may. And if my car is fairly gently driven, and I get a failure outside of warranty, and iot isn't covered by a TSB, that just means an excuse for the wife and I to EJ or LS swap it (not serious, but also very serious!)

But after doing their bean counting they've decided the cost/risk is such that it's better for them to just sell the cars with the known manufacturing problem that might affect only a small % of a small total volume of cars produced, than to issue a recall and get bad PR. Maybe they miscalculated ("My risk was calculated, but boy am I bad at math"). Or maybe they correctly guestimated that many of the early cars went to "enthusiasts" who are going to drive just hard enough to be able to deny warranty if needed; and the oil blockage/starvation is so much more likely to affect people who stay at the rev limiter for extended periods of time. Also, a lot of early GR86s were automatics, and the AT doesn't like to go all the way to the rev limiter unless you're flooring it. Quote:
You're assuming that all early cars had the same problem. It's possible that the earliest BRZs didn't have the problem, and then some robot got its calibration messed up, or they've "optimized" something incorrectly.

That's what I'm thinking (or hoping for, given my car was in the first batch that came over here). The initial run is always going to have more scrutiny/qualifications going on it, but once that goes away, and all the parts go on to their sampling plans, the chances of a calibration issue going unnoticed go up. Again, I don't work in the automotive industry, but the general rules of production system design are pretty similar across industries.

Oil starvation due to blocked passages is every bit as possible sitting at an idle or just driving casually. It isn’t as if the track driving is the cause.

I guess I was thinking if I only had a small blockage, and don't push it too hard (I'm never WOT for more than 7 or 8 seconds at a time), I would still get away with the amount of oil flow left. Or is that a fallacy as well? I'm extremely frustrated by this. I know the old adage about not buying a first MY car, but I thought this one was safe given how much of a carry over it was. Although this issue does seem like more of a manufacturing issue than a design issue, but still...
