So I just received two cylinder heads on a really good deal

1 is a 89 b16a marked pr3-4

2 is a b16a ctr marked pr3-2

problem is I I received only 11 of the 14 cam caps . I'm trying to identify which ones go to which head

4-2
4-1
2-2
2-1
3

The end caps I figured out and of course I know where the number 3 go .
Don't understand why these numbers are different then some other heads anyone explain the numbers to me and why they differ and or witch head the go to .

theres an order and direction in which they go on the head

theres no stamp to identify which head they belong to.

you will have to color match them to each head by the color of the oil buildup and by the scuff marks on the cam journals from each head that are present on the head and cam caps.
and then do the nail test at mating surface to be safe

 

it would help if you took some pictures also

 

Ok so what would be the line up of numbers on top of the head

I know 3 is in the middle Arrows pointing to timing belt so

Witch one goes in front of the 3 and witch one goes in back of the 3

2-1 >
2-2 >
4-1 >
4-2 >

If I figure that out I would have a better chance of matching them to the right head .

Also is I where to buy a set of cam caps do the have to Mach the casting # to the head casting # like Pr3-? 1234

 

I just posted a link bro. Theres like 1000s of closeup pictures in google search

 

Listen bro iv looked at all of pictures on google over and over if you actually look at the pictures you would see that you can't see the numbers on the cam caps in any of the pictures . I wouldn't be asking this question if I could find a good photo with the numbers .....

Why do I have four cam caps with different numbers ?

If you have your valve cover off of your head please read the numbers to me thanks

 

here you go found in google



and here another go

register and download a service manual
for the engine you need
Manuals - Downloads - Hondahookup.com
its pdf format so you can search through the manual by keywords

 

Is number 2 in the above picture
2-1> or 2-2>

Is number 4 in the above picture
4-1> or 4-2>

I know the rest of the cam caps I just don't understand way I have two of each number witch leads me to believe that maybe there different on the older the 89 b16a head pr3-4

 

what does middle one say?

 

color match to the head...

 

The middle just has 3> it does not have two numbers

I looked closely at both or the heads and did not find a color to match to the caps thro looking closely at the caps I can make my best guess .
I just don't understand why there are two different 2s and two different 4s

Lucky for me I found a little color atv on all the end caps that matched the b16a civic type r head pr3-2.
