Common Issue With The 6.6L LB7 (and what we do to fix it): Oil Pressure – The LB7 had one major design flaw above all others. And that was the use of a right handed thread oil pump nut that was known to back off and leave you without oil to supply your engine. This led to catastrophic failure of the bottom end.

When we find a problem, we fix it. And that is why all our LB7 engines come with the updated left hand nut.
