Upon the removal of the cylinder heads from each bank, we see that the crowns of the pistons seem to be relatively decent. However, that’s not the case for the bottom end of the block, with the oil pan capturing some debris from the damage. As predicted, one of the conrods was split in half, which led to the destroyed oil pan.
It seems that the V8 might’ve been contaminated by water. When water enters a combustion chamber, the piston won’t be able to compress it, which would explain both the fouled plugs and the destroyed rod.
In its day, the Bentley 6.75-liter was a respectable mill despite producing only “adequate” performance figures. It was discontinued in 2020 but was soon replaced by a 4.0-liter twin-turbo V8, as found in the Bentley Flying Spur.
