Do check it at zero lash or or with the preload? Also should i use 1/4 or 1/2 turn after zero lash? I am sure i will get different opinions on this but let me hear them.

They are oem lifters and 1.6 rockers. Of course i will also be using a solid lifter to be checking it with as well as starting on the cams base circle. I have seen where guys have done it with and without the preload. I just want to know which is actually the correct way to do it.

 

Depending on what lifters you have will determine pre load. Comp lifters are 1/8 pre-load. FYI, based on my expierence with the site you will get better answers and quicker if you have your car info in your signature. Just makes it easier for the moderators.
