Hi AMTS, i have some to add for the things to look out for on the 90 Series when buying used.
I found these crack in the LHF upper inner guard area towards the rear on my KZJ95R a few weeks ago.
I posted it on a 90 Series owners facebook group and found 2 other Diesel's with the same cracks in the same place as mine.
Haven't seen any Petrol's affected as yet, which is odd, as the Diesel has no Battery on this side of the engine bay like the Petrol's do.
See attached pics.
