INSTALLATION - UPPER INTAKE MANIFOLD
1)Clean and inspect gasket sealing surfaces.
2)Position new gasket.
3)Install the throttle body on the upper intake (if required).
4)Install upper intake manifold and hand start all attaching bolts.
5)Tighten bolts gradually starting in the center working outward until a torque of 12 Nm (105 inch lbs.) is obtained.
6)Install the front and rear intake manifold support brackets.
7)Install the oil level indicator and oil fill tube to intake manifold bolts (Fig. 155).
8)Install the EGR tube.
9)Connect vacuum lines to the following (Fig. 156):
Positive Crankcase Ventilation (PCV) Valve
EVAP Purge Solenoid
Power Brake Booster
10)Install alternator support bracket (Fig. 156).
11)Connect electrical connectors to the following (Fig. 157):
Manifold Tuning Valve (MTV)
Exhaust Gas Recirculation (EGR)
Throttle Position Sensor (TPS)
Idle Air Control (IAC)
Manifold Absolute Pressure (MAP)
12)Install the throttle and speed control cable bracket and retaining bolts.
13)Install throttle and speed control cables to bracket and throttle arm.
14)Install air cleaner housing and inlet hose.
15)Install the engine cover.
16)Connect negative battery cable.
SOURCE: Fill drill and tap aluminum manifold
Using a torch of any kind will be extremely difficult for filling a stub hole. Even trying to tig it would be quite a challenge. If you can get it clean enough," PC-7" or "All-Metal" filler putty will work. The metal MUST be totally grease & oil free. Use carbutator cleaner or some other good grease cutter and a small round brush. Pipe cleaners with stiff bristles work well. Use a pin or small pick to reach into the remaining threads to break up any solids. Work the filler into the threads and push a hard aluminum rod into the hole. The rod must be sliightly scored for the filler to grab on to it. Give it a full 24 hours to cure. Sand it flat, center punch, drill & tap. The new hole will be as good if not stronger than the origiinal. About 2 hours, not including the cure time.
SOURCE: I am installing an Offenhouser intake manifold on a Ford inline-6
put the halves together leave bolts snug, then bolt it to the head, now go back and tighten the halves together,
Testimonial: "thanks for the prompt answer/help."
SOURCE: What is the bolt torque settings for an intake
Intake Manifold 5/16 Bolts Non-Hardening sealers 25 ft-lbs
Cast Iron Heads 3/8 Bolts 30 ft-lbs
The torque sequence is snug all down then just star left rear then right front then right rear then left front and so on
Testimonial: "I appreciate the advice it helped a lot!"
SOURCE: need head bolt, intake manifold, and exhaust torque specs
Cylinder Head Bolt Step1- (25 FT.Lbs) Step2(45 Ft.Lbs) Step3(65Ft,Lbs).....Intake Manifold(35Ft Lbs)....Exhaust Manifold Center (20Ft Lbs) All Others (20 Ftlbs).....Thanks
SOURCE: What pattern should i use to tighten the intake
V6 or V8? Start with the middle right side,then across to the left,then
from one diagnal corner to the opposite side,and vice versa,till they are
all snug. I'd recommend using a torque wrench and getting the proper
torque values when doing head,and or intake manifold work,just to be
safe, but an estimated 50ft. lbs. should be pretty sufficient.
You might be able to get the specs in a Chilton's manual. Good luck.
