Besides the obvious displacement of the case, what are the differences between a 2.2 and a 2.4? In all the pics and the times I've seen both, the snout/front drive looks beefier on the 2.4. Or are my eyes just playing tricks on me since the snout is shorter than a 2.2? Does the 2.4 also have oil issues like early 2.2's? Does the 2.4 make the same nasty scream? Basically, school me!!!!
