For Example:

B18C5
<U></U>7301324

What are the numbers underneath the code and how can you tell what year the motor is?

Thanks

 

those are serial numbers. i believe the only way to find out what year motor that is through the number are through computer (honda, dmv, etc...)

if you have a longblock look at the head, right above the exhaust manifold. there will be little circles with numbers. it will have the year on there. say a 1999 would have something like (9/9)

 

That's the engine serial #. I've heard that the first digit is based on the model-year, from when the engine was first available. So that would be the 7th year for a USDM type R engine????? So either my understanding is wrong, or you just made up that number...

i don't believe this is right. lol

they are simply serial #'s. an identity for your motor. (ie. social secrurity)

 

its right under the distributor.
