Craigar Posted December 21, 2024 Share Posted December 21, 2024 (edited) 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?

el_freddo Posted December 23, 2024 Share Posted December 23, 2024 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.

Craigar Posted February 26 Author Share Posted February 26 (edited) 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 by Craigar 1 Link to comment Share on other sites More sharing options...
