go tdc on the camgear, and the valves for cylinder #1
would be closed you can adjust those valves,
you then turn the crank pulley 180*
or have the camgear rotate 90* (same thing)
and repeat on cylinder #3 the rotation goes 1,3,4,2,
good luck on adjusting and yeah,

.007 Intake and .009 Exhaust, Firing order is: 1,3,4,2. Adjust your valves using the firing order and you cant go wrong. :td:

Hey there noticed this is a pretty old thread but I am about to adjust valves on my z6 as well and I am wondering about engine temp I have been looking around and some forums say its best to do first in the morning when engine is very cold and others say to just let the engine cool for about a hour or so?? Just curious if it really attests?

As long as the actual engine is less than 100* F, then you are good to adjust. with heat everything expands, so if you adjust them with the engine too warm, once it cools down it'll be way too loose when cold.

Care to share that link?

It is best to stick with the .007" intake .009" exhaust, as the engine warms up the lash is reduced by metal expansion to just where it needs to be.

valve adjustment should only be performed when the engine is cold..it DOES matter if the engine has been ran and what spec. u set the clearances to

on a d16z6 u got the specs correctly and set em to that and please make sure the 10mm valve adjusting nut is properly torqued as well and while ur there u mite as well replace the valve cover gasket and spark plug tube seals

Once you have both intake and exhaust adjusted on cyl #1 rotate the crank as shown so you can do cyl #3
