Yep, it seems that the fuel and oil mixture attracts dust more than anything.

This means, the air filter should be very efficient (restrictive), no cheap pod filters.
And oil filtration with catch can should be taken to the highest level. Could be solved by creating a very efficient catch can (full with steel foam). Or routing the PCV to exhaust system like dragsters do, but that`s the expensive option.
