EA82 replacing manifold gaskets

[Craigar]

after getting the bolts out (serious slow torture on the rusted encrusted ones  https://www.ultimatesubaru.org/forum/topic/186067-any-new-ideas-for-the-old-intake-manifold-stuck-bolt-problem )  then had to clean up the surfaces - the right side was so pitted I ended up taking it down with a medium diamond hone. The first and second image are from just scraping it with a sharp putty knife and carefully filing with a old "cross hatch" file - not happy..

 

 

 

 

so I worked it for about 3 minutes total with this medium diamond hone. Walla!

 

 

 

did the same to the bottom of the manifold - but only removed what lines, pipes,sm0g stuff, etc. I needed to in order to lift it up only a few inches, so I had to use my selfie camera and it doesn't focus (kinda like my eyes now    )     as I'm hoding the cell phone camera facing up .. kinda like holding a minature yoga pose

 

Here's a couple of images using a "dental mirror" showing the ends of the manifold's water galley, I think I need to clean it up more BUT it was getting too cold and the wind and fog were rolling in..

 

.. and before I stuffed the sock in the intake port I looked down into it and I see a pile of "oxide crystals" so I'm going to make sure that intake valve is closed and try to get a skinny rubber hose attached to a vacuum cleaner down past it and knock most of it lose with a chopstick .. if yea all think that's a good idea?

Good idea to me. Keeping anything out of the intake/cylinders that shouldn’t be there is always a good idea for engine health!! 

You could remove the cam belt and allow the cam to rotate to its free-spinning zone. This is when all valves are closed in both cylinders on that bank.
