Peregrine Reliability
Considering the Whirlwind was basically unchanged and in operation from 1940 to December 1943, makes it difficult to say the Peregrine was unreliable. The Peregrine was as reliable as the Kestrel, which had a long and successful career as an engine in aviation. Rolls Royce dropped the Peregrine because the Merlin took precedent and the Peregrine was only used in a single aircraft.

The Peregrines ran hot but this was disguised by using 100% ethylene glycol mixture, and the over heating issues were more to do with the engine installation than the engine itself.

In February 1942 the reliable Peregrines did have some failures. After a few failures No 263 Squadron was grounded while the issue was investigated by Rolls Royce. A small T-piece that fed oil from the oil pump to the camshaft drives and rear supercharger bearing had cracked. When this happened the loss of oil to these areas quickly resulted in an engine failure. Rolls Royce quickly produced a modified T-piece, along with a set of piping that was less vulnerable to vibration. By the 4th March the engines had all been fitted with the new piping and the squadron operations were resumed. (Source: "Whirlwind - Westland's Enigmatic Fighter" by Niall Corduroy).
