When Magnussen’s car caught on fire today, it made me wonder: what’s burning? The fire was coming out of the exhaust, so I can’t imagine what was actually burning. And then, what does that mean for the engine? Can it be repaired, or does the whole engine need replacing? There are limits to how many engines a team uses each year, correct? I’m guessing that will play a role in this too. It’s not the first car fire this year, so I am also wondering how all of the teams are doing this far into the season with regards to using up all of their allocated spare parts.
Probably oil. If something goes pop it can damage seals, breach the block etc. Hot engine+oil = smoke and fire.
That makes sense. It was a red-orange slow-ish fire. Still not good. If it is just a seal, and as long as everything was still lubricated, I suppose it could probably be rebuilt.
