Machine work for the 6.6L L5P Duramax (2017–2021) includes precise machining to prepare engine parts for better fit and performance. This often involves decking the block and heads to make surfaces flat. It also includes boring or honing cylinders to fit pistons correctly and resurfacing heads for a tight gasket seal. Technicians inspect, polish, or balance parts like the crankshaft, rods, and pistons. These steps keep compression strong and boost efficiency and reliability. Proper machine work helps parts fit perfectly, reduces wear, and improves engine life and performance.
Building engines the way the OEM factory should have in the first place.
