As the title says .... I wanted to make a DIY valve adjustment tool from an old socket or spanner but cant find the size of the locknut on any of the how to guides. I could take my valve cover off to check but am hoping someone here knows?

Thanks

 

I believe its 10mm.... but whilst im on the subject are most hondas 10mm. I just read somewhere that non vtec hondas are 12mm?

 

10mm

 

The lude is a 10mm. I have a nonvtec accord also at home which is also a 10mm but I believe an LS I did a valve adjustment on was a 12mm, correct me if I am wrong.

 

Everywhere I have seen this tool for sale the 10MM one is cheap (less then $20), but the 12MM is like $40.

 

H22 is 10mm along with most other honda engines including V6. 12mm are H23, B20 B18 nonvtec( LS, GS, special edition integra ect.

 

Well heres how the tool came out...

I found an old 10mm ring spanner and chopped the head off


Weld the head on at this angle


and hey presto...


I also had a broken spanner kicking about which I used to make a turning handle for it.


Its not pretty but should work
