Different Spitfire.
Speaking of the P-38, I was reading that while it was a hell of a plane, it was also a bit of a handful. There was a sequence you had to perform with the engines or risk damaging them. It did well in the Pacific theater but not so well in Europe, the weather colderer that in the Pacific and the altitudes higher:

The P-38 performed usefully but suffered from a number of problems. Its Allison engines consistently threw rods, swallowed valves and fouled plugs, while their intercoolers often ruptured under sustained high boost and turbocharger regulators froze, sometimes causing catastrophic failures.
Arrival of the newer P-38J to fill in behind the P-38H was supposed to help, but did not help enough. The J model’s enlarged radiators were trouble-prone. Improperly blended British fuel exacerbated the problems: Anti-knock lead compounds literally seethed out and became separated in the Allison’s induction system at extreme low temperatures. This could cause detonation and rapid engine failure, especially at the high power settings demanded for combat.
The P-38’s General Electric turbo-supercharger sometimes got stuck in over-boosted or under-boosted mode. This occurred mainly when the fighter was flown in the freezing cold at altitudes approaching 30,000 feet, which was the standard situation in the European air war. Another difficulty was that early P-38 versions had only one generator, and losing the associated engine meant the pilot had to rely on battery power.
In an article on ausairpower.net, Carlo Kopp noted that in their early days in the European theater, “Many of the P-38s assigned to escort missions were forced to abort and return to base. Most of the aborts were related to engines coming apart in flight….[due to] intercoolers that chilled the fuel/air mixture too much. Radiators that lowered engine temps below normal operating minimums. Oil coolers that could congeal the oil to sludge. These problems could have been fixed at the squadron level. Yet, they were not.”
