The video walks through diagnosing the oil cooler versus head gasket, pulling the head, inspecting pistons and rod bearings, identifying non-original Mahle pistons, pulling sleeves, and reinstalling bearings, seals, and liners in detail. Best for owners facing similar oil/coolant contamination symptoms or planning their own in-frame rebuild.
