I'm ready to install my engine, but I want to check valve lash cold, just to make sure they have it ballparked before I start it up and adjust hot.

What is the procedure to check/set the lash cold?

Thanks everyone,

BG

I know the procedure, but what is the appropriate setting for valve lash cold? I only need it to run for break in, then I can set hot. I just want to make sure they're not too tight or loose during break in.

What do people typically do for a rebuild, set the gap at a thousandth or so looser than spec to account for expansion?

thanks,

BG

Sure

Actually, if you figure it, the lash will get tighter as it heats up. I'd set the lash 2thousandths looser to start.

Lash on a first start is always done cold first. When it is warm for the first time you can do a torque n lash . After a first move (drive the car) I would lash again.....and check for leaks.

That first lash can be any clearance that makes it run well at cam breakin rpm. Looser will tame a wildo cam down a bit.

On a street motor I would cold lash to spec.....breakin the cam (we are not getting real hot) and relash.

I prefer to do static lash while warm.......you may have another method.

I'll set a few thousands loose, do the break in, then set lash hot to spec.
