Before to replace Long Block Engineering is asking to follow these checks for an overheating suspect diagnosis: 1) BLOC-CHECK-KIT (BLOCK TESTER or CO2 Tester) 2) CYLINDER LEAKAGE TEST 3) COOLING SYSTEM LEAKS -INTERNAL ENGINE LEAKAGE INSPECTION If no one of this checks (1-2-3) fails it does not need to replace long block ( even less full engine) but just the component causing the coolant leak."

  Summary

  3.6L PSU Long Block Misfire DTC codes and/or rough idle and/or valvetrain noise. These conditions may be related to worn intake camshaft high lift lobe(s), and intake rocker arm(s) high lift slider. High mileage failure (10,000-60,000 miles). 1. Remove the valve cover(s) per the released service procedures. The use of a stethoscope or DTC specific cylinder misfire codes can help to locate the condition to the left or right bank. 2. Once it has been visually confirmed that there is wear on the high lift intake lobe(s) & rocker arm(s) slider, there is a special service kit for this type of repair which should be used, instead of replacing the complete engine/long block. This kit contains the parts required for the repair (intake cam, rocker arms, sealer and gaskets). Once it is confirmed that the repair will be done using the camshaft/Rocker arms kit, it is also important to confirm that the vehicle being repaired has the latest calibration/software update for oil pump operation mode (high pressure mode) during engine start up. RU, VF, WL & WD vehicles already include the latest oil pump mode in all 25MY and beyond. 24MY service releases are also available. JL & JT were updated as a running change in 24MY and beyond (08/15/24 & 08/19/24 respectively). 24MY service releases available. DT was updated starting 25MY and beyond. If the vehicle to be repaired is a 24MY vehicle with a service release available, please follow the released service procedures to update to the corresponding calibration/software update.
