I need a part number or a link to where I can buy a replacement oil control orifice o-ring, for my D16Z6.

I've tried hondaautomotiveparts.com: under "Cylinder Block- Oil Pan" it appears to be number 34, but it does not show on the list.

The o-ring seals between the center-ish of the cylinder head and the rocker-cradle. I assume it supplies oil pressure to the cams/ rockers.

Here's a poor picture that I had been using in another thread. Although the picture is bad, you can see the orifice above the bolt hole, and I believe there is supposed to be an o-ring as a seal.

Thanks

 

I'm still needing this information....

 

Found it:
HondaAutomotiveParts.com, look up a 93 Si, it is under "Valve-Rocker Arm" it is #17 in the picture. They list it as "Product Number 18255".

This is for anyone who may need this in the future.

 

I saw this post the day you posted it and remembered to look up the part for you. Unfortunately you already found the part number for that site but in case you (or anyone else) is looking for the OEM part number it's 91312-107-000. I rebuilt my own motor and made notes of all the seals/gaskets I picked up for my motor so if you need any help don't hesitate to ask.

Also, aside from www.hondaautomotiveparts.com there's also www.thehondapartsstore.com which does include the OEM part numbers.
