Q: Do I need to redesign the oil tank?
Y: HASEGAWA: "We preferred to modify it to improve performance, but that's fine. During the season we can improve any part of the engine, so we may also change the oil tank, but for now we can live with it."
Q: Have you reduced engine power in these tests, as a precaution?
Y. HASEGAWA: "We have very little time to run, so sometimes we are not going to full power and in some tests we are checking the car or analyzing some data, so you do not need to go full power all the time."
Q: What are your plans for next week?
Y. HASEGAWA: "We would like to introduce the latest version of the engine and test it as soon as possible, every time we have an engine, we change something, so next week we will have another engine."

-Shape of oil tank, or specifically speaking the baffles inside the tank, its (the baffle's) arrangement turned out to be inappropriate so that it cannot take in oil properly when under G-force during running. Therefore caused oil pressure drop.
They noticed the issue in filming day running on Sunday already. Applied fix that's possible in impromptu style at venue but wasnt enough due to time restraint, so they were prepared for encountering trouble to a degree. (info in the article)
-It's not a serious issue. However it's located in a place difficult to reach, so you have to detach engine from car in order to repair. It was a combination of new PU plus new car, so normally it only takes 2 hours to exchange the unit, but it ended up taking much longer.
