Cylinder Boring Tips

Lightweight block castings have become very prevalent in our market. Since the overall mass has been reduced, the controlled stresses have become an important factor in the block’s integrity. To ensure integrity, we must recreate that stress by using a Torque Plate when boring and honing.

Always begin by torquing your main caps in place to correct specifications. Next, install a torque plate and torque in place using final assembly torque specifications. Also, we recommend using correct length bolts. If they are too long or too short, they may abnormally stress the block. The future will even dictate correctly torquing all external motor mounts and related accessory brackets.

Allow .003″ minimum material in the cylinder bore. Remove broken and partially severed material by honing after the boring operation.

A code P0299 for lower- than-normal boost can be one of the most challenging DTCs to resolve. You might think it is a code for a leak, but it could be more than a leak. The criteria for setting the code is very basic. The engine management system is looking at the desired boost pressure and the actual boost pressure, if the actual and desired do not match for the conditions.
