Why do GGR always use a torque plate when reboring the cylinder block?
It was an early discovery of ours that the cylinder bores distort alarmingly in the engine when the cylinder head is tightened down. The mis-shaped bores can then lead to excessive piston ring blow-by, and the piston to bore clearance is larger than necessary. Using a torque plate, we can guarantee round bores, and tighten up on piston to bore clearance, reducing piston slap, and improving piston ring seal.
