Is it a block problem for it too be only the left rear corner I think not. Poeple with high boost would been having lots of block problems.

That is because that is where the coolant has no out let therefore there is more heat on cylinder 7&8 allowing for more detonation in those cylinders. You see when you have heat you can have a lot of timing or you are destine for disaster
