What really causes Corvette C7 Stingray LT1 engine catastrophic failures?

The bullshit cover story GM cooked up to cover up the disaster of LT1 engine obliteration on long term Car and Driver test car, with oil filter chunking out metal fragments is an insult to super low IQ four legged species (not to Corvette enthusiasts though). 

So what really lies behind these multiplying engine failures, should someone discard the oil filter bullshit?

A review of the LT1 design leads to a very interesting observation:  a thrust bearing that is literally half of LS engines design. 

Here is a LS type of thrust bearing, a full circle design, characterized by sturdy design and plenty of thrust area to resist crankshaft play.

 


And interesting new LT1 thrust bearing design (on number 3), with thrust area only in the block  area and very limited thrust resisting surface.

 


Can this design be the real culprit of all EFFECTS resulting in LT1 engine failures, including bent connecting rods, failed main bearings and pistons?

This line of thinking certainly can be supported by existing evidence, including botched torque tube replacements.

With 180 degree bearing, the ability to resist excessive force is cut in at least half, anything formerly concerned minor in the past can become a fatal blow to this new turd called LT1.  Thus, factors like improper torque tube alignment or force exerted by the torque tube converter due to heat related high pressure can cause enough force to literally obliterate the entire engine.  Then of course, geniuses like Juechter blame oil filter or bad weather for destruction of the engine.  This design looks right down stupid.

Of course neither +Tadge Juechter or anyone else in +General Motors will provide a plausible explanation, blaming oil filters for a fatal design flaw or God forbid admit a fuck up and redesign the bearing.  Until this happens, buying any version of the new Corvette should be off anyone's mind, especially since GM is inclined to find any possible excuse to blow off the buyers.
