December 21, 20241 yr 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?

December 23, 20241 yr 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. Cheers Bennie
February 26, 20251 yr Author Got it all back together, driving it for a few weeks and runs maybe even better than before - sounds much better without the worn out water pump rattling - , no leaks! BUT didn't pass CA smog (engine light is off when motor is running) and was 2 degrees to advanced so reset it and ran a bottle of " CRC Emissions System Cleaner" .. double your money back... in a half tank of gas so going to try to pass test again. Thanks everybody for the support Edited February 26, 20251 yr by Craigar
