SNIP

The front oil pickup has me baffled. It is from a 88 turbo
engine. It has what appears to be four very small helmholzt resonators.
For what reason I have no idea. Mazda knows something about this
they are not saying in any of the SAE papers I have read.

How about a high frequency pulsation in the oil pumping system

critical freqs and get good flow?

Heck the pickup pipe is only about six inches long.
That is some real detail engineering on the part of Mazda
to discover that and attempt to correct it.
