[QUOTE="Johnny O, post: 1039638, member: 61743"] My opinion is that the higher pressure is so the engine can run at higher temperature for emissions reasons. I replaced the 20 lb cap with a 16 lb about ten years ago and no issues since. Engine seems to run at the same temp but remember the thermostat only controls the minimum temp, not the maximum.
