Znalazłem specyfikacje silnika n47 niestety w języku angielskim i jest napisane ze maksymalne cisnie to 3.7 bar. „The pressure limiting valve protects against excessively high oil pressure, e.g. when starting the engine with the oil cold. It protects the oil pump, oil pump drive, oil filter and oil cooler. The pressure limiting valve is located on the pressure side between the oil pump and oil filter. It is fitted as close as possible downstream of the oil pump -in the N47 engine, in the oil pump housing itself. The opening or cutoff pressure in the N47 engine is 3.7 bar.” „Ciśnienie otwarcia lub zamknięcia wynosi 3.7 bar” wiec od 4 do 6 wydaje mi się stanowczo za dużo. Ktoś potrafi się do tego odnieść ?
