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?

The oil doesn't slosh there... It is delivered there by the ushrods to lube the rockers and valve guides/stems..

Anything you do to the PR tube to retain slosh will also retain oil IN THE TUBES thus keeping it from the SUMP where it can be picked up again and recirculated. even the windage tray does this in stock form and thats why we either don't run it or we heavily modify it.

I make tabs that weld to the pick up tube and retain slosh and they work well. I have tubes with these welded on already if anyone wants to try one and see the differences..



I knew that oil is delivered to the head via the push rods, and returned to the sump through the tubes, and the oil doesn't really "slosh" into the heads, but rather enters the heads by the centripetal force created in a turn.

So, which is it Jake? (IMG:style_emoticons/default/confused24.gif)
