While installing my valve cradle on my D16Z6, before tightening the bolts, I saw this sitting next to a valvespring... It was on the exhaust side on top of where the #2 cylinder is... I assume I knocked it out of the cradle, but I cannot figure out where it goes, or what it is. Please assist. I apologize for the terrible pictures, but I don't own a camera, only a cell phone. The object is cylindrical and solid. It has no beveled edges nor is hollow. (No, I don't know how to re-size images, apologies again)

 

It goes on the rocker arm

 

it goes in the cam rail assembly it keep s the rocker arms straight

 

im a goof

 

Vague... BUT, I got it. It is a "synchronizing piston". It is in the rocker arm on the intake side (VTEC side). Thanks.

Question: Is there supposed to be a rubber o-ring here?

 

[QUOTE=sleepingciv;39024226]and take the oil jet out or vtec wont work FYI
use a screw put it in the hole and pull it out i use drywall screw. put in by hand turn the screw in till it stops use pliers to pull it out


Wait.. what? Why would VTEC not work with the oil jet installed??!!

 

i goofed

 

Time out: the "oil jet" you are referring to is the oil control orifice. This is not a "mini-me", this is a D16Z6 matching head and block. If Honda deemed it proper to install this orifice from the factory, I side with them. Thanks for the help earlier, I need to start a new thread to find the o-ring for this....

/ thread.

 

my bad man i dont know what i was thinking. i was thinking about the block lol
