Ford V8 Intake Manifold Bolt Tightening Sequence Diagram - Stud Locations
Bolt tightening sequence diagram showing numbered fastener positions around a manifold/valley cover.
This document is a black-and-white line drawing showing the intake manifold bolt tightening sequence for a V8 engine. The manifold is drawn from a top view, with an arrow at the lower left labeled "FRONT OF ENGINE" establishing orientation. Sixteen fastener locations are shown as circled numbers (1 through 16), indicating the order in which the intake manifold bolts should be tightened. The sequence alternates across the manifold: positions 1, 9, 11, 3, 15, 7, 5, and 13 lie along the top (driver-side head) row and positions 4, 12, 10, 2, 16, 8, 6, and 14 along the bottom row, working generally from the center outward. Two positions — 13 and 15 — are specifically called out with arrows labeled "STUD," indicating those locations use studs rather than bolts. The drawing also depicts the central carburetor mounting pad with two throttle bores, a fitting near position 13, and a dashed circular opening at the front of the manifold. No torque values, part numbers, or year/model applicability text appear on the diagram itself; a reader learns the correct bolt order and stud locations for reassembling the intake manifold.

Frequently asked questions
- What is the intake manifold bolt tightening sequence shown in this diagram?
- Sixteen circled numbers mark the order: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, alternating between the two sides of the manifold and working from the center outward. Top row front-to-rear reads 5, 13, 1, 9, 11, 3, 15, 7; bottom row reads 6, 14, 4, 12, 10, 2, 16, 8.
- Which intake manifold fastener positions are studs instead of bolts?
- The diagram labels positions 13 and 15 with arrows marked "STUD."
- How do I orient the diagram to the engine?
- An arrow at the lower left labeled "FRONT OF ENGINE" points left, so the left side of the drawing is the front of the engine.
- Does this diagram give torque values for the intake manifold bolts?
- No. The diagram shows only the numbered tightening sequence and stud locations; no torque values are printed on it.
