68 Intake Manifold Repair

[Mark Milchuk]

How difficult is it to replace
the water outlet on a 68 Intake Manifold.
Is it hard or expensive?

How do you replace it?
How much would it cost to have someone else replace it?

Sorry for the beginner question but this is my first
restoration and I am learning as I go.

Thanks to all that help,
Mark

If it is original it will most surely be a problem. Galvanic corrosion will have made the twp parts one for the most part. If you are very handy and very patient you night remove it. There are several induction restorers that will do this and they do it often enough to have a few tricks.
Jerry MacNeish, (410-781-0418), has done several for me. Cost is determined by hours spent.
Good Luck

Re: 68 Intake Manifold Repair

I have done a few of these over the years, and this is a job that can be done in your own garage if you have patience. I usually start out by drilling the center of the fitting out, leaving just a thin shell of the original fitting in place. Then with a Die grinder or dremmel tool, I slowly grind the fitting away on the inside until the threads just become barely visible. At this time you can usually take a sharp scribe or pick and slowly pick the old fitting out one thread at a time. It is slow going, but I do not believe that I have ever spent more than a couple of hours doing one.

Mark,

For what it is worth, I just changed the fitting on my 65 365 HP manifold. I use Castle products, and sprayed it about four days in a row with Castle Thrust. When I put the wrench to it it came out very easily and slowly by my choice and left no damage to the aluminum. A little patience can go a long way.
