fine words indeed but it doesn't alter the fact the pick up pipe gets blocked and whats causing it ( its nit the oil that much I can confirm ) so is it wear on internal items or is it a fact the sump filter is useless

 

pick up pipe to you

 

Update: Got the car back last night... running great, cost: $0.00!!

They apparently did about $1500 to $2000 worth of work, including replacing oil lines, pick up, inspected cam bearings for signs of wear due to low oil pressure (they were fine), engine flush, oil change, etc.
