Hello all. I am finishing up my 1998 lumina 3.1L lower and upper gasket set. I purchased the fel-pro kit at advance auto (http://forum.mazda6club.com/index.php?showtopic=118263&st=0#) with all the needed gaskets. Also got new injector orings, fuel (http://forum.mazda6club.com/index.php?showtopic=118263&st=0#) line orings, thermostat, upper lower hoses, heater core quick disconnect and so on....

I have enjoyed the project and appreciate the help I got from this site. Our mechanic quoted $1673.00 for the job. He recommended that I junk the car (http://forum.mazda6club.com/index.php?showtopic=118263&st=0#). This is my sons car by the way.The car had other issues like #2 and #4 fuel injector bad. Cam sensor cracked and defective. #3 and #4 spark plug wires open.

So I have invested $330 so far and I am ready to start her up. BUT I found a broken vacuum port on the upper aluminum manifold front drivers side near the pcv.

Now this port is sheared clean off. I was saddened as the excitement of the completion and start up slowly sank like a tropical sunset.

Here is a pic of a 3.4 with the same port that is broken on my 3.1 for illustration purpose.

Does anyone have a fix for this port that they can share other than get a new upper manifold from the salvage yard. I'm so close but yet so far away.
Thanks
Rick

$1673!!! damn, im in the wrong buisness!! i just got done doing the same repair last week, tis' the season..ha ha. but seriously you will proably have to remove the upper intake manifold ( for ease of the following repair ) i think your best bet is to drill and tap a screw-in fitting into that port. OR you could cut the screw in fitting in half and try to jbweld it over the exisisting port just make sure you dont accidently cover the open port with jbweld. how did the nipple get broken?

Manifold repaired with 1/8 inch soft copper nipple with a slight flare on the end and some epoxy. Used a 1/4 inch bit and vacuum.
