Since I see this question a lot I made my own handy picture...

 

Great picture! :thumbup:

I might attack this a little more in the morning ( 1:am now)and see what I can find. I'll get back to you guys...thanks for the help by the way.

Well...got into it today...but not much...I expect when I do the engine clean I'll see it more...BUT...a couple of blasts of WD40 later (it is a penetrating fluid)...
D15B1 appeared!
I didn't really get a look at the other numbers...but now I know for sure...D15B1.


Thanks for the help guys...and the great "visual aids"...greatly appreciated!

yah wd40 works wonders when cleaning up and degreasing an engine, thats what i used on my zc when i put it in a couple weeks ago.
