if your asking if we know...then yes i know. if you asking on how too then you must state which engine and if you have a cam(s) upgrade.

What IS valve adjustment? Is it somthing with adjusting hydraulic lifters? Valve lash would be the only thing i would think that could be adjusted in the valve train, but im pretty sure there is something i don't know.

I have a skunk2 Stage II cam in a z6 head on a y8 block. The entire engine has been rebuilt with aftermarket parts. Since I didn't have the timing belt at the shop they told me the only thing left to do with it was to have the valves adjusted. I know what it is, but how do you do it? What tools do you need, and is it done cold?

there are different specs when the engine is hot and when it is cold, i would perferably do it when its cold, go to like checker or auto zone and pick up a chilton it tells you exsactly how to adjust valves, you have to have it on top dead center and then have to rotate the cam 180degress and then adjust and then another 180degress and so on, but pick up a chilton and it tells you step by step

tools required
17mm 10mm socket and wratchet
10mm box end wrench
flat head screwdriver
feeler guages

i adjust my valves as per stated
.006 intake .008 exh all motor (aids in a little more lift and duration)
.008intake .010 exh turbo or nitrous(aids in keeping the valves seated longer too cool itself down to help prevent burned valves)

Valves should only be adjusted when engine is cold with temp of it less than 100 degrees F.

Step 1...Remove Valve Cover.Remove Upper Timing Belt Cover.Rotate Crankshaft counterclockwise until No. 1 piston is at TDC of the compression stroke.Up mark on camshaft pulley should be on top,TDC marks should align with cylinder head upper surface or TDC groove should align with pointer on back cover..see pic below

Step 2..Loosen adjusting screw lock nut on cylinder No. 1.Adjust valve clearance to spec on all valves for No. 1 cylinder.Turn Adjustment screw until a feeler guage slides back and forth with a slight drag.Tighten lock nut to spec and recheck valve adjustment..Cylinder No.1 is done

Step 3 Rotate crankshaft counterclockwise 180 degrees(camshaft pulley rotates 90 degrees) Up mark on camshaft pulley should be on the exhaust side.Adjust all valves for Cylinder No.3

Step 4 Rotate crankshaft counterclockwise 180 degrees(camshaft pulley rotates 90 degrees) Up mark on camshaft pulley should be down(both TDC grooves will be visible again).Adjust all valves for Cylinder No.4

Step 5 Rotate crankshaft counterclockwisw 180 degrees(camshaft pulley rotates 90 degrees) Up mark on camshaft pulley should be on the intake side.Adjust all valves for Cylinder No.2
