I personally wouldn't worry, 102s are tough as old boots
Funny that you say that. The M102 in North America is not highly regarded, and many people feel the M103 six to be much stronger and longer lived.
I have driven two M102 2.3L 8-V engines to over 300,000 kilometers, and the next owners took them to over 400K, and one had it's top end done last year at 515K.
"Tough as old boots." Excellent way of putting it.
