Very interesting ... Post a pic, plz! You say it's hard to see, but just do your best.

 

Engines that come from japanese importers sometimes stamp the blocks with their marks.
It depends on who it came from but its not as uncommon as one would think.

 

yea but the d16z6 is usdm not jdm??

 

im at work using my cell phone i cat get pix on here yet sorry

 

Yea sometimes machine shops, or engine rebuild places do the same thing.
Like attarco for example.
Nothing to worry about.
