Each engine is completely disassembled, cleaned, inspected, precision machined, and rebuilt to D\u0026amp;J Precision Machine specifications.\n\nThe block is precision machined and matched with OEM-spec Tier 1 pistons and rings as required for proper fit and performance. Cylinder heads are inspected and resurfaced with recut valve seats and new valves. The upgraded L5P top-hat valve stem seal design helps prevent valve seal failure and improve long-term durability.\n\nThe engine is assembled with Tier 1 MLS head gaskets and upgraded ARP head studs for improved sealing and clamping strength. An upgraded L5P oil cooler helps maintain lower engine oil temperatures and reduce the risk of piston cracking and related engine failure.\n\nThe oil pump is pinned to help prevent oil pump rotation and loss of oil pressure. The crankshaft and camshaft are keyed to provide positive timing and component retention.\n\nNew bearings, thrust washers, lifters, valve springs, and freeze plugs are installed as part of the remanufacturing process.\n\nThe Precision Plus Long Block is the most complete LML long block available, reducing parts transfer and installation time. Each engine comes with the valvetrain, rocker boxes, valve covers, and intake manifold pre-installed. It also includes the harmonic balancer, flywheel, mounting hardware, upper gasket kit, oil filter, and break-in oil.\n\nEach engine is measured and tested in-house using D\u0026amp;J Precision Machine's RMC ETS test equipment before shipment. The engine undergoes a controlled test sequence to verify key operating conditions, including oil pump pressure and volume, cylinder compression, and cooling system integrity. This in-house testing allows D\u0026amp;J to identify potential issues before the engine leaves the facility, providing an additional level of quality control and helping ensure the completed long block is ready for installation and service.\n\nThe result is a professionally remanufactured LML Duramax long block designed to provide dependable performance for everyday driving and towing applications.","brand":"DJPLB100111","offers":[{"title":"Default Title","offer_id":47839333810230,"sku":"DJPLB100111","price":18949.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0108\/0364\/2432\/files\/precision-plus-long-block-engine-chevrolet-gmc-silverado-sierra-6-6l-lml-2011-2016.jpg?v=1790884693","url":"https:\/\/ca.bddiesel.com\/products\/precision-plus-long-block-engine-chevrolet-gmc-silverado-sierra-6-6l-lml-2011-2016","provider":"BD Diesel Canada","version":"1.0","type":"link"}
