This is the intake manifold with what was the MAP sensor nipple drilled away to accept the fix.
A firewall type vacuum nipple from Summit Racing. (Thank the FSM I had this onhand)
On the bottom of the intake manifold is a very small and even more delicate nipple that is the take off for the MAP sensor. Just trying to remove the small vacuum line from it to get the manifold off the motor is enough to break off this nipple. How do I know this? If you have to ask…. The fix was thankfully simple. A Firewall type vacuum fitting an O ring and an 8MM drill and here you go. Better than new. With the turbo there could be easily 30psi of boost in the manifold so the repair had to be substantial and secure.
