I have been asking this question for quite a while now and a I never seem to get a clear answer.....I wonder if anyone truely knows!!
How do you read the "clock" info on the front of the engine head?
There are 4 "clock locking" emblems on the head...SO WHAT!!! How Do You Read Them
I am trying to fing the exact date and make of my engine but no one can help!!
I know, I know the block says B18C and nothing else...
They say the head has a mark on it but no one can tell me where...

Does AnyOne Know????????

Exact date shouldt matter

freedm

I agree but it matters to the owner...LOL! I am just curious how to find the date...
and how are you sure its the type-r and not the gsr..Theres a differance of 180 hp to 195 hp...thats something else I would like to know..
and with all honesty...THANK YOU j bizach for speaking with me!!! (The name cracks me up too)

j_bizach

Well ud proly have to find someone who works at a honda plant the marks that u talk about are production line marks that are only really used by the factory to help identify problems with casting and production mistakes.
Do you have the head that came with the motor
The head will tell you which it is

freedm

Yes I have the original head..but where is the markings?

freedm

and it deffinatly doesnt have LSD

j_bizach

i believe that its on the intake side off to the side and above to intake ports

j_bizach

p72 is gsr and p73 is type r

j_bizach

alrite its on the exaust side above the 4 cyl exaust port

freedm

OK!!! now we're getting somewhere!!! I do see P72 so I assume I have the gsr..No Problem That is very acceptable!..now to find out how to find the exact date of engine...is the 95-97 all OBD1 for JDM?

j_bizach

lol alrite here the deal not all are obd2 95 is obd1 then in 96 the standard went to obd 2 so a 96 nd up is obd2 now how to tell the diffence is waat im figuring out.

freedm

no heres my delima...i'm trying to put this engine in my 90 crx...I need to know if its obd1 or obd2..thats why I need to know so I can figure out which jumper harnesses ect...It's pretty crazy.I'm to the point I need to wire this up!

freedm

thanks for your time j bizach...as soon as all this is done ...I will be listing a post so others will know all the info I know..and that you helped me figure out!!!!!

freedm

you are sure of this dkrex001 ? Do you know what the other numbers stand for?
and is this a pic of an integra motor or civic?...just making sure there is not a differance in the way they dated them...ya know?
thanks!

freedm

mine engine shows 9/3..I would assume this makes it a 94?..the first year they made them

j_bizach

The jumper harness for obd1 round and yellow
obd2 gray and square

shy_lee85

this is definitely for sure...this is how you tell..

freedm

they didnt make a B18c in 93 so I would be safe to say that mine is a 94? OBD1

j_bizach

nope they didnt make a b18c in 94 does the motor hav a harness that come with it

freedm

yes it does have the original harness...I know its not an obd0 harness..and I'm not sure what an obd2 harness looks like

all-mtr-teg

If your head says 93 then it's a 94 motor. Lots of heads were cast in 93 and used in 94 and even 95 motors.

freedm

Thanks all-mtr-teg!!!! Your stern post gives me confidence!...Any idea what the other "clock" numbers mean for curiosity sake?
Thanks again!!
