To those in the know, installing aluminum cylinder heads requires a careful procedure of tightening bolts in a specific pattern and in multiple stages. In fact, the “Ford Escape Workshop Manual, Volume 2”, on page 303-01B-52, explains:
NOTE: New cylinder head bolts must be installed. They are torque-to-yield designed and cannot be reused.
Install the bolts and tighten in 6 stages in the sequence show.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten bolts 90 degrees.
- Stage 3: Loosen one full turn.
- Stage 4: Tighten to 40 Nm (30 lb-ft).
- Stage 5: Tighten 90 degrees.
- Stage 6: Tighten 90 degrees.
This procedure secures the head to the block without warping. Corners cut at this stage of the game, vastly increases the risk your drive will end stalled on the shoulder in a cloud of sweet smelling steam.
Encouraging an artist is much the same. Artistic expression requires a healthy measure of freedom. If a creator’s head cheerleader rushes to the final pair of 90 degree turns, the prime mover risks locking up with hydraulic pressure. As much as I’d like to see a professional production schedule, out of the chute, I must remember the tow trucks of my youth. Mama’s no fun when she’s seized and fuming.
A full audit of my blessing accounts comes up in the black. This site provides a great excuse to blow a Saturday conjuring visual puns about math and art with my wife, even if none of y’all are in on the joke yet.
