I'm rebuilding a D16Y8 I grabbed from an unknown car, and I'm trying to get piston rings, but I'm told the rings are different sizes depending on if it's a 96-98 or 99-00 manufacture. The only markings on the block are as follows:

D16Y8
2786999

Then on the back side:
P2E
1-2

Can anyone tell me what year or year range this engine is from? Or do I have to pull the pistons and measure my rings?

 

I guess the other question is do these two year ranges actually have different piston rings? I was looking on the Hastings website and they showed different part numbers for 96-98 and 99-00 D16Y8's, but according to the catalogue on hondapartscheap the Honda Part Numbers for rings for a 97 and 99 EX are the same. So I'm kind of confused.

 

interesting. i wouldn't expect them to be different, but i guess better to figure out what you have and be safe than sorry.

99 EX D16Y8 5sp------P2J-4
00 EX D16Y8 5sp------P2J-3 "99" stamped on right side"

you will find this alphanumeric code on the front of your cylinder head

 

Thanks, this is what I was looking for. Unfortunately there is some new confusion that comes from this. I grabbed this full swap from the junkyard, including the D16Y8 engine and an Si manual transmission.

However, my head is marked P2J-2 and 97, which doesn't even jive with any of the codes shown in this listing. This is a Canadian vehicle/engine, so maybe the codes are somewhat different?

 

On the lower left side of the block, on the intake side, right above the oil pan, there is a green VIN tag, It is the same VIN as the chassis.

https://www.fleet.ford.com/maintenance/vin_tools/

type in the VIN on the site and it gives a generic break down of the car it came from:
Year, make, model, trim, country of origin, etc.

 

there should be a vin number on the front of the block there was on mine u can go to carfax and type that vin number in and it will tell u what year and mdl that engine came out of

 

do you have the head too. then check the head. there should be those circle thing above the header. the second circle will tell you what years is it. I think its the second circle.

 

this ^^^. quick way.

 

So... p2j-8 is from a 98??

 

Honda catalog shows the same part number for ring sets 96-00 for the D16Y8 which is 13011-P2F-A01. There are additional sizes for oversize for rebuilds .25 over and .50 over but they also share similar part numbers for 96-00.

 

I looked at my car and i have a p2j-4 but not a 97 stamp on the right...the stamp is 98. Can someone help me?

 

It means it's from a '98 and not a '97 (also those date stamps are often a year older than the model year of the car)
