How to disassemble the old commercial Buick gl8 six-cylinder 3.0-displacement intake manifold?

Hello, this intake branch pipe needs to remove the turtle cover on the intake branch pipe, which is very troublesome. It needs tools. I suggest you go to the repair shop or 4s shop to disassemble it.

1. Remove the throttle control unit; Remove the engine hood; Unplug the vacuum hose (arrow) from the intake pipe to the brake booster;

2. Unscrew the bolt of the fuel distributor and press out the locking pin of the cable guide from the fuel distributor (as shown by the arrow).

3. Disconnect the electrical plug (arrow), remove the cable on the air inlet pipe and put it aside; Turn the activated carbon canister solenoid valve n.

4. Unplug the plug 1 and remove the throttle control unit J338 (arrow).
