"A 216 is a sludge producing factory from the day it was new until it dies of old age. Anyone who has ever pulled the oil pan on one can attest to the stench of that crud."
Would the smell from the 216 be matched by the smell of a low-pressure (1941-1953) 235?
I do not recall any harsh/odd/foul odors from my high-pressure 235 and 261 engines. They do drip a little oil but they do not put exude a stink.
