Corvette C7 Stingray LT1 engine destroyed by grenading? oil filter-the lamest cover story yet?

As already mentioned here , Car and Driver long term test Stingray's LT1 engine obliterated itself into a pile of worthless scrap metal and apparently +General Motors "experts" informed Car and Driver staff that the culprit was a defective oil filter and Car and Driver chose to mindlessly repeat this official cover story.

Can this actually be possible?  An oil filter losing chunks of itself, spitting them out into engine oil which subsequently delivers the metal chunks to the rod bearings and puts them out of their misery?

Does this sound far fetched?  If this sounds far fetched, this is because IT IS... it is not possible to happen or at least it was not possible until now, until the newest Corvette and this fine LT1 engine came out.

For a typical engine, including LS GM engines, there is only one source of metal shavings in engine oil-the engine itself.  These shavings, if present and unless the bypass valve is open, are intercepted by the filter medium.  And there is another small detail, a mesh on the oil pick up, making +Tadge Juechter story a sure candidate for Ripley's BELIEVE IT OR NOT EPISODE.

Typically, rod bearings fail due to improper assembly, incorrect crush, engine oil starvation and  problems with crankshaft.  Now, it is already well known that thrust bearing failure is an issue for LT1 and it is also known that inferior albeit cheaper oil is used as OEM lubricant.

Here is a direct request to Tadge Juechter: have enough integrity and honesty to show that failed oil filter and the damaged bearings, along with the shavings collected.

Until this is made public, this is nothing less of the lamest corporate engine failure cover up ever.
