I just read the DIY for Oil in Spark Plugs and I have a question about removing the camshaft holder bolts. I've got an f22 engine and my question is whether or not i need a deep-well 8mm socket to remove the cam shaft holder bolt in the picture (red arrow). This appears to be the same bolt for the valvel cover acorn nut. Just want to get all the tools before I start is all, thanks.

you need either a deep 12 mm socket or a 12 mm box end wrench . I would personally use a deep 6 point 12 mm socket ,, using 6 point sockets you have less chance of strippng bolts and nuts

 

That bolt does look a lot like a 12mm. The accord factory service manual (see pic above) shows a 8 and 6mm....is this wrong?

 

that would appear to be bigger than an 8 to me.... it looks like the wrench in that photo is a 10mm and the bolt appears slightly smaller than the one in question so I think a 12mm is acurate....

 

I just don't understand why the service manual shows a 6mm and 8mm

is that service manual 91 specific or does it cover a range of years?

 

its for a 93', the 91' manual doesn't include that diagram.

 

The manual is probably saying it's M8 thread size. Not wrench size...

 

8 and 6 mm are the threds sizes not the wrench sizes that you will need

On hondas 99.9 % of the time 6 mm thread you will use a 10mm tool ( wrench, socket)

8 mm threads .. you will use mostly 12mm , but some 14 mm tool

10mm threads you will use mostly 14mm and 17 mm tool

so when they say it is a 6 mm or 8 mm bolt or nut , that are talking about the thread pitch and not the tool needed to remove it

 

Ahhhhhhhhhhhh, thanks guys.
