I read your post On Longevity, Displacement, Efficiency and Technology in
Conversions with great interest.
I'm certainly not knowledgeable enough to contradict any thing you
delivered to the archives.
However I do have a serious question.
You briefly mention *add a windage tray*.
I've noted that the Porsche type IV uses a windage tray but I assumed it
was basically because the sports cars are driven hard in corners and
maneuvers. Assuming that they would be splashing oil into the cylinders.
I have considered securing a windage tray to install in my 2000 cc type
IV engine in the future if and when I split the case again.
If having a windage tray in a big Westfalia vehicle has any advantages
I'd be interested in knowing why and what the advantages of having one
installed are.
