Mitsubishi Pajero Engine Failure - Generation 4 Pajero / Montero / Shogun

Engine issue with 3.2 4M41 common rail diesel in 2008 NS Mitsubishi Generation 4 Pajero / Montero / Shogun
Taking off from the lights on the way home from work and lost engine power. There was no big bang, but it was smoking like a chimney and felt like it was running on 3 cylinders. Dipstick was pushed out of the sump and oil everywhere under the bonnet.
I suspected a cracked piston from the outset and this video covers the troubleshooting process I went through to determine the problem and cause:
• Compression test (remove upper inlet manifold and glow plugs)
• Injector inspection (remove rocker cover and injector)
• Inlet ports inspection (remove lower inlet manifold)
• Bottom end inspection (sump removal)
• Exhaust ports inspection (remove EGR cooler, turbo, exhaust manifold)
• Cylinder inspection (remove timing chain sprockets, camshafts, cylinder head)
In the end, I decided to replace the failed engine with a low mileage NX (pre-DPF) engine, which I’ll cover in part 2
