Re: Solid roller cold lash setting?

BB,
The best way to do this is to set it a few thousanths loose, then start the engine and get it good and warmed up. Once it is warm, set the valves to the proper hot lash spec. Then, let it cool down overnight and check it. You will see how much it changes when it cools off and the next time you can set them cold based on that.
The amount that the lash changes will be different from one engine to another, depending on head material etc. The best way to do it is to set it hot, but on a street driven engine you can get close enough with the method above.

Hope this helps,
