NO! I do not agree that the engine should be hot. It should be warm enough to get it off of cold idle to help from tossing oil all over the place, but for the accuracy of the adjustment, the engine temp is inconsequential. Mechanical cam valve lash adjustments change the amount of play (lash) in the valve train. With a mechanical cam the parts expand with heat and the valve lash changes with different temps. The expansion of the valve train parts is the reason for mechanical lifters to have lash. Most mechanical cams are spec'ed with the hot lash. With a hydraulic cam, all you are setting is the amount of preload on the plunger inside of the lifter. Whether 1/4 turn, a half turn, 3/4, or even a full turn makes no difference on how the engine will run. If it is quieter at 1 turn (for some unknown reason) than at 3/4, leave it there. Because with a hydraulic cam all you are setting is preload, the hydraulic lifter automatically, constantly, adjusts the lash to zero, the temp isn't an issue. I hope that helps. RACE ON!!! |
