- We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block.
- We bore the block back to the crankshaft center line and hone the block to RA13 finish.
- The piston diameter measured to the nearest .0001 inch matched to cylinder bores.
- The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface.
- This is mandatory for proper sealing of a MLS Gasket.

Common Issues With The 6.6L Duramax (and how we fix them)
- Head Gaskets- This was the first Duramax engine to use the variable geometry vane turbo
- It was so rely problematic for the failures with head gaskets.
- While our business is engines, we also encourage the customers to fix the cooling issues and update the LLY with the larger later year model LBZ fan and radiator.
- But we will take care of our end. And that is why we make sure that all our Duramax engines come standard with headstuds.
- So you don't blow a gasket.
Optional Parts are not installed. Optional parts are covered under the manufacturer's warranty and not by CHOATE.
