GM recalls 721K trucks with 6.2L engine

It sounds like the new lawsuit is from a firm that specializes in tort lawsuits. I'm sure more will creep out of the woodwork.

Here is more info on the recall, when you can go in to have it performed, and what to expect:

Units that are included in this recall but don't need a new engine, get a 10 year 150k mile special warranty.

OuThis engine design has to be 20 years old now. Why are engine flushes not part of the fix if it is debris?

The only thing a higher viscosity oil does is provide greater shear resistance between bearing surfaces. It seems to me there are structural issues that thicker oil is trying to fix.

This should never happen in an engine design as old as this one is...

Being a retired mech engineer, at one time I was able to do both bearing journal and roller bearing, tilting pad etc. calculations. You get the proper viscosity, bearing does not ever wear, as there is no contact. Tilting pad bearings have lasted plus 100 years. Next thing to consider is material fatigue under point cycling loading.
A lot of times you can just wing it or use simple calculations, but wtf, if the design is for a costly massed produced item, critical stuff like aircraft, rocket, prime mover, nuclear, etc., you better know your ****, or get help with the design.
A company deserves the consequences of not controlling the design, testing and QC processes.

Sure is good to have a pair of Ford 32 valve motors that luckily happen to be sorted out as well as a Nissan 4V V8 that runs like a clock as the V8s in our little fleet.

But, all it takes is one parts supplier to cause problems, like in this case.
