Hrmm... That was an obtuse comment, I guess.
I was referring to the fact the L series engines don't suffer from a lot of windage.
Primeraly because of the large cavaty where the t/chain runs, allows them to 'breath' quite well, while also allowing excellent oil drainback from the top of the head.
Which is also why you don't need a baffled sump for a fast road/track car.
Nissan RB series engines however, are a whole other kettle of fish...
