Hi thor
Had the same 3.0 engine in my terrano year 2002 covered over 106k not a single problem always serviced well in side service times.
Just got a newer 2007 patrol same 3.0 engine don't expect any problem with this one either.:smile:
However have fitted Turbo Boost gauge, Exhaust Gas temp gauge, and oil Pressure gauge. Before doing any mods..... :smile:
