Nobody said all failures from McLaren. So remember what Hasegawa said after a retirement of Alonso. "There's any problem with PU"Chicane wrote: ↑08 Dec 2017, 13:221) Majority of Honda failures were ''HEAT'' related failures of MGU-H. Honda struggled pretty much entire season barring the last three races with MGU-H bearing failures. So how a Mclaren technician installing those components is beyond my comprehension.
2) Hasegawa is a principled man who spoke the facts and not try to spin it in to Honda vs McLaren.
3) Recent article points out to how without Mclaren's help Honda may not even have made it to the grid in Melbourne 2017. These are not my words but words of Honda's Nakamura.
4) Nakamura has only good things to say about Mclaren as to how up until the second preseason test Mclaren were encouraging and supporting Honda but once Honda failed to keep their end of the bargain where they had promised earlier that they will have a working reliable PU in second preseason test things started going south.
Remember what Wazari san said about where some mgu-h parts coming from.
It seems you don't know importance of packing for cooling
