Rocker Arm Assembly Reassemble
So I bought a use motor and the rocker arm assembly has been taken apart on the cylinder head. I looked in the Honda manual and there is not any info on reassembly. So, my question is has anyone put one of these back together after the rockers have been scrambled up? I know that they should not be moved for their factory position. I talked to a honda tech I know and he said I might aswell throw the head away. Does anyone know the key to my roller rocker puzzle?

Each rocker is a 3 piece matched set that should not be interchanged, but you can do so as long as you test them.
You will have to do a manual VTEC pin test on each of the 8 assemblies, to be sure the pins dont bind (since they are now mismatched)
Just make sure that the VTEC pin slides freely among the 3 piece rocker, once you have slid them onto the rocker shafts.
They may also have a 3 piece combined width which can be measured by micrometer. This will ensure there is no excessive oil clearence, or a tight rocker.
You are welcome to send it to me and I will return it assembled.

yeah not hard to do, having a shop manual helps. When you get them all lined up in proper order on the long dowels zip tie every set of rockers - 8 sets, this will allow for an easy drop onto the head once it is all done and will keep the pins from falling out. Elastics work well too. If you need a shop manual layout of the valvetrain pm me and I can email you a pic.

You could do a little detective work, if you had the cams that correspond with the rockers, being used, you could try to match up wear patterns, or use them as clues to try and match the rocker arm pieces.

Typical answer from an incompetent source. Tell him he should be working at Wendys.

I’ve been reading lots of your advice given to others over the past few months as I’ve been building my motor and appreciate all the info your previous advice
to others has given.
I’m looking at the service manual and the rocker arm shafts drawing is incorrect when I compare it to the actual shaft. Looking at the oil holes from the ends, one is closer to an end which looks like it should be going toward the front (timing gear) or #1 cam holder. The shafts appear to be identical for intake and exhaust side but should they both be going in the same direction? I’m not sure if I should be following the picture as the drawing is not 100% accurate to the actual shaft and I would think they would go in different directions as the rockers are facing opposite sides of the head as well. I want to be sure I get everything in the correct order as I got it used and not sure if it was taken apart and reassembled. I actually put it all together over the weekend and just got to thinking about it so I’m going to pull it all apart again to confirm direction.
Im not sure if your still active on here but would appreciate your or anyone’s help.. Pictures or other service manual references will highly be appreciated...
Thanks All!
