| drop into the oil pan, where it will be drawn in through the oil pump. The oil pump will suffer damage as a result since there are no seals per-se for the gear pump components - the clearances between the gears and the housings are the seal itself. When debris goes through the pump it will scar up the softer aluminum labyrinth seal faces of the housing and sometimes mildly scathe the gear ring's outer face as well. As for turbo damage, you have to consider that there is an oil filter just downstream of the pump itself which filters out debris before it passes into the block's distribution galleys. OEM and quality aftermarket oil filters are going to filter out around 75% of the particles that are ~10 microns or larger and the use of the turbo oil feed lines and filters that we offer are going to perform as a secondary filtration system which will catch all of the remaining bits that are 10 microns or larger. I Built the oil/filter lines primarily for the initial miles put on a freshly built engine, but it also provides long-term service from there. There will always be some degree of debris that does not come out of the block while cleaning for a build and bits of this that pass through the turbochargers will damage the delicate bearings and seals. I haven't seen any evidence that suggests a spun rod bearing will damage a turbocharger though - most of the larger bits that really wreak havoc on turbos are already filtered out by the primary oil filter.
