Which number in an engine number indicates the year of which the engine has been manufactured? thanks :D

CivicSpoon

The year is stamped on the block by itself. It's right around the center of the head on the front. It will have a circle around the 2 numbers, with an arrow between the numbers pointing to the month it was manufactured. Like this:

Hey civicspoon do you know what the other three stamps are for?

treborpaul

is it possible that the year is displayed on the stamp the first one from the left (d-series)? thanks btw my engine code is d15b2099993 and on the engine block it is displayed:
d15b
2099993

is it a d15b or d15b2 ? thanks

wow im gunna go check my JDM D15B block now lol

treborpaul

lol and let me know if the year is the first one on the left dont know if mine is a jdm d15b or d15b2 i think it is jdm d15b but not sure

TravisCadello

well i thought about that pic and i looked at my engine and didn't find ****. and now i think about it Civicspoon that is the head year not the block year! the exhaust manifold is on the head no the block.

TravisCadello

And how do you not know what it says? if it says D15B then its D15B if it says D15B2 then its D15B2 ? what do you mean?

treborpaul

as the first number of the second line is 2, i was thinking that it may be a d15b2

Date of Manuf. Feb, 1996. And on the right is the arrow pointing the day(s): 1. So, it's made on Feb. 1, 1996.

CivicSpoon

Correct, but the head is part of the engine right (as the OP was asking)? I have no idea where the date is located on the short block, or if it is at all.

Your engine is a D15B. The bigger numbers and letters are your engine code. I personally don't know what the numbers underneath it mean (the 2099993), maybe the specific engine; like block #2099993 that was manufactured that year or something.
