Also, there is a blogger(content uploader) on Weibo (Chinese social media), who actually have a chance to ask a dealer‘s chief mechanic in person regarding this issue on the 10th anniversary GR86 release site(FUJI 86 BRZ Style 2022)

- Including the Racing factory team and GR86/BRZ CUP designated vehicles also confirmed the problem of oil seal blockage. Just like the info from JP posts，even if the top of the filter of pickup tube is completely blocked, it can ensure that the oil can be drawn from the side because it's five-sided box shapes, not one side (like pics below). So it is necessary to check the oil pressure frequently after intense driving.


- No official recall for this issue. If the problem does occur during normal (non-extreme/aggressive, a further explanation of “normal" needed) driving, all vehicles with maintenance can have their engines replaced according to the warranty contract. It is necessary to pay attention that, to any failure accident in track driving, the manufacturer will refuse the warranty (you can read the Warranty Booklet for this, may just be applied on JDM).

- The design of the stock car is roughly corresponding to 90% of the driving conditions below 4000 rpm(non-intense). it is necessary to make corresponding modifications, such as the oil pan baffle plate. The baffle plate is to prevent the engine from oil starvation during high G cornering/acceleration when driving on a circuit. also, most of the RTV that peeled off will be blocked on it and will not fall off.

also, STI also provides the oil pan with baffle plate for BRZ CUP car, the part number is ST11109Z2000, just google it. or you can buy the plate from well-known aftermarket brands like Cusco/Tomei/GReddy, they are all suppliers for CUP cars, like the pic shown below.
- For potential prevention, besides the plate, you can check the dipstick regularly, since some owners suggested that the sealant may stick in the oil dipstick. And you can install an oil pressure metric gauge in advance to prevent low oil pressure.

I think for early adopters, asking the dealer to install a baffle plate is one of the better preventative action that can be taken at this time.

- Dealer performing the work means you are not going to void your warranty.
- You can bring this problem up with the dealer so the tech can examine your oil pick up and at least clean up the excess RTV around the oil pan and oil pick up.
- The baffle should allow the pick up to be submerged in more oil so the other 4 sides can pick up more oil even if the top surface is clogged.
- According to the article, the baffle is supposed to stop the RTV from making it to the pick up, though I am not sure how.

However, the down side is that if your pick up was clogged and but have not caused enough damage, you are now left with a partially “worn” bearing. Something everyone should ponder carefully.
