STuTZ693 Posted October 29, 2011 Share Posted October 29, 2011 The valve adjustment spec is 0.006 - 0.008 inch when the engine is warm. What would be a good cold adjustment that would be close to the warm adjustment as a starting point?Thanks Link to comment Share on other sites More sharing options...
Guest Jim_Edwards Posted October 29, 2011 Share Posted October 29, 2011 It would be helpful to know what specific engine you are working on. If the engine is a rocker tube engine I'd suggest no more slop than .0010 cold and if it looks like that might be too loose go to .0009. You just don't want the cold adjustment to be so tight you'll end up bending the snot out of push rods as the engine reaches operating temperature, but you also don't want things so loose push rods jump out from the rockers before the engine warms up.

Rusty_OToole Posted October 29, 2011 Share Posted October 29, 2011 If you are rebuilding the engine or cannot set the valves hot, set them to the same spec cold. Then check again when you get it running.Chrysler products were set "hot" and I am sure they never heated them up before they set them at the factory. They would be checked at the 1000 mile service, after the engine had some break in miles. Link to comment Share on other sites More sharing options...
