On the car in my signature, I am re-assembling the head and it occurs to me that perhaps there should be sealant on the mating surface between the head and the end camshaft caps.
There wasn't anything there when I took it apart but gosh darn it seems like a good idea.

 

There should be a thin layer of hondabond used. Or else it will leak.

 

Yes, if you don't have any hondabond get some, buy it at the parts dept @ honda. I use that **** on everything!

 

"Grey" Right Stuff will also work just as well. (Made by Permatex, same company that makes Hondabond.)
