This Pajero was in my workshop to diagnose an engine noise. The engine is making knocking type noise from front timing cover area.
it was failed timing hydraulic tensioner. This is one of the common issues with V6 engines if you don't replace them when replacing the timing belt. This tensioner tensioning procedure can apply for 6G75, 6G74 3.0 l & 3.5L engines. Mitsubishi Pajero, Montero sport, Mitsubishi Magna, Mitsubishi Galant/380.
So, I hope this video helps someone when doing this kind of job.
Torque specs & some important steps below

Special precautions -
Disconnect battery earth lead.
DO NOT turn crankshaft or camshaft when timing belt removed.
Remove spark plugs to ease turning engine.
