so....... i have heard that some lq9/lq4 have some early bearing failure due
to untrued bearing install or bearing journals from the factory.... and that it was only certain block castings ? can anyone verify ya or nay and if so......
does anyone know where to find out which block casting numbers have or dont have this defect ? gonna toss a cam in mine and need to know if
i should align hone and toss in new bearings.

thanks,

 

ttt
has no one heard of this issue ?
