Germany goes for centrifugal flow turbojet engines?

No it wasn't, the British engines were more reliable and were demonstrating greater time between overhaul than the German engines, this is well known.

All of the Jumo 004's problems had nothing to do with the compressor. The Germans were forced to save alloying additives (nickel, first of all), as a result, the heat resistance of materials for the hot part of the engine was insufficient. The limiting factor was the combustion chambers, the next was the turbine blades - even hollow air-cooled turbine blades did not provide the required material durability. If the Germans had enough skilled workers to produce the hot part of the engine from suitable materials, the reliability of their engines would not differ from that of the British. Under nickel shortage conditions, the Germans could use any type of compressor with exactly the same result. German engineers chose the most promising type of compressor and created quite good engines, as the further development of jet engines showed. The centrifugal compressor was a temporary dead-end solution.

Any report on the Me 262 will tell you that its engines were excessively unreliable.

Except it had nothing to do with the compressor.

It does when your aircraft are grounded because your engines have a time between overhaul of less than a quarter of that of your opposition. A grounded jet fighter with unserviceable engines is as useless as no jet fighter at all.

Jet engines, while requiring very close tolerances and exotic metals, the same can be said about High Inline Vees.

You can't use garbage 1020 steel for the rotating parts, but very good, very strong, expensive alloys, and need high heat resistant alloys for the valves, different alloys for the camshafts rather than just chilled Iron. And balancing all those rotating bits is an art and a science at this time

In comparison, considering what alloys were set aside for reciprocating, could be redirected for the turbines instead.

Jet engines can be build cheaper than inlines, and faster as well.
And at the end of the game, they run on kerosene or low grade gasoline, no high octane fuels needed.

People forget that if an reciprocating engine was run at WEP levels for long, they would need to be pulled apart as well.

So what if an engine has a 20 hour life, when they are cheaper and faster to build?have more spares

All Engines are consumables at the very high HP we are talking about.
