Adjusting valves with cold engine

You can adjust hydraulics stopped as well. I used to do so all the time. All the "chivy guys" used to splash oil all over the floor until one day it occurred to me that Mopar V8s are not normally adjustable.

So I just took a "chivvy" and figured out how to adjust them for zero lash, then with the engine off tighten them all down by whatever amount. 1/2 turn used to be common. Then just let 'em sit for 10 minutes and go have a cup of coffee.

You do have to pay 'tention to what you're doin'
