Engine Block
WARNING: This page is about a different car, the 2024 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.
Thoroughly clean the oil pan and engine block gasket surfaces.
Use compressed air to clean:
- Oil gallery at the oil filter adaptor hole
- Front and rear oil gallery holes
- Multiple Displacement System (MDS) oil gallery holes in the valley
- Oil feed holes for the crankshaft main bearings
Drilled and tapped holes should be free of debris upon assembly.
Once the block has been completely cleaned, apply Loctite® PST pipe sealant with Teflon 592 to the threads on the front and rear oil gallery plugs and coolant drain plugs, then securely tighten the plugs.
