How would AMuS know this number. Why would anyone tell them a figure, let alone an accurate one. It's incredibly vague anyway. The crankcase on an F1 engine is also part of the chassis, as well as the attachment point for the oil pumps and MGUK. There are hundreds if not thousands of parameters which could be out by this supposed 0,2mm, depending on how the part is specified, toleranced, and measured.

They have updated the report and now it says 0,02mm.

That's a bit more like it.

If plausibility is inversely proportional to the value of the quoted figure, then... I say it was out by 0,002.

That's a lot more like what I would expect. On something the size of crankcase that could be a linear expansion issue do to improper thermal controls in the machine room or coolant tanks.

AMuS always reports such detailed information and I always ask myself how they get them. They claim that they ask engineers and related people in paddock, but who would give away such sensitive information?
They're also reporting that Mercedes' spec 2 engine will have a performance boost of less than 10 hp.

Yeah right, they often seem to be the only ones to get those 'insider informations'.

Bottas told that they were going to use the old spec engine in Hungary (probably like most or all of the other teams too), but will go with the new one there now as their plans changed.

Most likely office employee hearsay!

AMuS:
During the inspection of the new units, deviations of 0.2 millimetres were found on the crankcase. The problem could not be solved in the short time.
8 thou might as well be the grand canyon of crank journals. That's a big screw up at this level. Would they even run .002 clearance normally?

Is there any definitive information of which component or area they are talking about?

Yeah. The rest of the article is behind a paywall.
The original machine had a base-plate of prefabulated amulite, surrounded by a
malleable logarithmic casing in such a way that the two spurving bearings were
in direct line with the pentametric fan, the latter consisted simply of six
hydrocoptic marzelvanes, but the ambifacient lunar vaneshaft clearance pocket was 0,02mm short in the long dimension, preventing side fumbling from being effectively prevented.

Hmmm. My google translate is screwed up

Is that quote legit? Because I'm an engineer myself (software and electronics) and tbh that sounds like it was directly lifted from an episode of Dr Who.

As a software/electronics engineer you probably haven't even heard of a turbo-encabulator. (Its the mechanical equivalent of the multi-spacial reflection spinner, the polaron limiter or the automatic phaser crystal.)
