On Topic - Anyone remember reading about, Type IV push rod tube mod. Options

[SpecialK]

I can't remember where I read it, and it was several years ago, but someone did a mod on their push rod tubes in an effort to keep the crankcase oil from sloshing into the heads on hard cornering. I think it had something to do with attaching the end of a Type I PR tube to the "case side" of a T4 tube which made it extend farther into the case. This supposedly prevented (to a certain extent) as much oil from entering the heads during a hard cornering, yet still allowed the heads to drain normally.

Anyone heard of, or done this?

Wings welded to the windage tray don't help that much. The problem with the Windage tray is that the oil can't get back to the pick up fast enough. I ususally cut out large windows in the windage tray to help speed oil return.

The crank does not have as large a problem with windage because it is mounted above the camshaft. This tends to really help. Most engines the crank actually sits down in the oil pan so the crank tends to whip the oil into a foamy mess.

The biggest problem is pumping to much oil into the head. That is a draw back of having pressure fed shaft rockers, but they are reliable. The Tuna can helps a lot. I ran one on my daily driver and never had problems. The bottom of the can sits just above the bottom of the engine bar. Rememeber the 914 engine is between the wheels not like the beetle where it hangs out behind the wheels. So ground clearence is directly related to wheel and suspension travel, not necssarily ground travel.
