Is this fixable?

Hi guys - Just scored a complete 87 Motor for my 1984 GN conversion. This water neck on the intake looks removable but not sure?

You can get a new one pretty easily.

pull the bolt that secures the hold down and pull the housing out. It may be tough as that cooling system looks pretty rough.

Yeah that comes out. new and old ones are available through the vendors and members here on the board

Awesome! Now I just need to save up for the rebuild

Put a big socket inside the neck with an extension on the end of it. Then rock it up and down to remove with the least difficulty possible. That one is going to need a lot of soaking in PB Blaster first.

And clamp the neck to the socket so it becomes one rigid fixture. That'll make getting it out a lot easier.

Or since you're going to rebuild it, pull the manifold and soak it first.

Great idea Earl. I'll do that since I plan on sand blasting it anyway. It'll be a while before I get to the motor. I'm building the suspension right now, but I'm also gather parts for my LC2 swap. Thanks for your help.

Before you sand blast it, BLOCK OFF the insides, and the EGR paths.

It's impossible to get all the sand out before building the engine...

....but you can bet your ass it'll start coming loose after it's running!

Yea - I was a little worried about that. I plan to completely mask all machined surfaces and block all holes. The last thing I want is sand in a brand new block...
