Any further thoughts? I have gotten mixed replies on this question...
As the temp increases, parts expand. As it gets colder, they shrink, right?
So, what is .004 at 70 degrees, is .005 at 40 degrees? .006? It can't be that much of a difference, because when the motor hits 250 degrees or so, at most the valve clearance should go to .001-.002 as parts expand, right? Assuming expansion is linear based on the temp...
So, if I stick with .004 at 40 degrees, at temp, the valves may be slightly loose, right?
For most cars, you see a recommended "range" in the workshop manuals. The pelican parts manual and bruce andersons book only mention the .004 figure...
Any thoughts appreciated. Motor is in the garage, on a stand, and the temperature is unlikely to hit 70 degrees any time soon...
