Good question, rather than just mouth what I read, it got me to thinking about it. The conclusion I came to is...probably:-)

I can't concieve of what the interior of the engine looks like at high RPM, but "stuff" has got to be flying around in there to beat the band. All that oil "probably" doesn't neatly slip by the crank and rods to be sucked out and put in its proper palce. It would seem that the atmosphere in there might be a tad thick, in which case, knife edging should be of help. I over filled my engine last change. The motor responded by quickly pumping it out into the catch can via the crankcase vent....oops.

As for boat tailing the webs, you may be right. I don't think that it was invented with the coming of the 7R case, but I've been wrong before. Larger radii on the corners shouldn't hurt, but may not be worth the time and effort.

I've been over on the 914 list debating the virtues af the type 4
vs the 911 six. Exagerated hp claims roll of me like water off a duck.
