1-2-3 Intake Manifold Removal


Recommended Posts

In the process of removing the 1-2-3 intake manifold to get at my change-over valve for replacement. I can get to the six mounting bolts easy enough but am having issues with the fuel rail. What is the best way to remove supply/exit lines from the rail? The aft fitting has a nut that looks accessible, the fore fitting looks to slip on... should I expect a fuel spill when removing? Also, the electrical connectors to the injectors appear to have a small wire retaining clip on the bottom side. Does the wire move straight down? Any other advice on this project would be appreciated!

1999 base - 65k

I'm not a mechanic. I just heard it is very hard to remove it. The easiest way is: when you change clutch, lower your transmission with engine and then remove intake.

I've got 99 with 70K miles and problem with secondary air valve system. I'm just adding chevron fuel addon and everything is fine no CEL for past 3 months.

Waiting for cluch replacement in future.

You can lower the engine enough to make this job much easier without any major work. Loosen the three bolts on the front motor mount. They are on the bottom of the car and easy to get at. You will also need to loosen the (many) bolts on the cross braces.

I have done this a couple of times using 4 jack stands and a floor jack in my driveway. It isn't very complicated.
