Moosens. Please take a look at the last image in my last post ".. and before I stuffed the sock in the intake port (to block dirt and debris) I looked down into it and I see a pile of "oxide crystals" https://www.ultimatesubaru.org/forum/topic/186408-ea82-replacing-manifold-gaskets

Thank you! The bolts didn't break probably cause they're hardened or tempered, they have a #7 on the top of the bolts. Yea first I'm going to hit the bolts and threads with a wire wheel but probably use a die on this particularly bad rusted one - the rest didn't look as bad - 3 of them came out easily. Will see Started a new topic for doing the gaskets and hopefully getting it back together without putting some of the spaghetti back in the wrong holes.. https://www.ultimatesubaru.org/forum/topic/186408-ea82-replacing-manifold-gaskets

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?

Got em all out without breaking any - I don't think Ive stripped the holes either but haven't cleaned it up yet. For this really tough bolt I decided to use a "paint stripper" heat gun on high for about 15 minutes and it still wouldn't budge so drilled a 2nd hole down closer to the threads, earlier had drilled a hole about in the middle of the column to get the penetrating oil down into the crud in the bottom inch of the column also. After drilling this second hole and then using a lot of penetrating oil, then heat, I had progress had to heat up down by the head for at least 10 minutes with paint stripper heat gun, that's why my aluminum shield has turned golden brown .. I tried a M.A.P. torch but it was to scary and causing way to much smoke for my comfort.. and wiggled back and forth tell I could get about 1/4 turn, came back next day tried it cold no t so much movement so heated it up again and kept working it back and forth - but not going as far in as out.. then add more sauce.. do it again and eventually.. Here's the bolt right after I got it out - I used a lot of B'laster penetration oil, and couldn't get it moving with the 3/8" impact gun - had to really push and pull on this ratchet - really hoping the bolt wouldn't break,, kind of amazed it didn't

.. and about a week ago I sprayed em with my 20 year spray can of Liquid Wrench, - which I discovered 3 days ago had lost all it's pressure probably cause I unknowingly banged the head on it, probably shutting the hood.. So I bought a new spray can of B'laster and sprayed and soaked it a few more days - no cigar So here's the specs of a very nice portable 3/8" torque wrench I just bought from Home Depot on sale for $140 with battery and charger Lightweight Design. Heavyweight Performance.

Impact Wrench Kit with 2.0 Ah Battery, Charger, and Bag and it didn't seem to move any of em at full torque, even trying in both directions.. So I cleaned the oil + road dirt mix off the passenger side intake manifold area (to lessen the chance of a bon fire) and only M.A.P. torched it for about 3 minutes total cause I've never done it before and was getting smoke and embers and nervous and cold and it was now dark outside where I'm working on it and the crappy harbor freight "free head lamp" was turning off all on it's own way to much - even after messing with it a lot.... and "amazing to me " got the bolt loose closest to the windshield loose! BUT it didn't want to go "looser" and "tighter" back and forth ( CCW and CW ) only looser so went about 2 turns and going to give it chance to soak more over night. - and the head wasn't really very hot, maybe 110 F. Progress, not perfection ... One down, two to go Grrrr ,, I mean "patience..."

Well I didn't even think about a rethread kit but you say that making me think it's inevitable so when and if I gracefully get these bolts out it'll probably need to be rethreaded with maybe some bigger threads or you got to put in like a helicoil and for heating it up with a torch should I use a map torch or a propane torch, any preferences? Thanks

I was gone for about 2 months and I finally got back to working on this car and ended up drilling a small hole on the outside corner of the manifold where the bolt goes down to try to get penetrating fluid or blaster down in there and then went and got myself a modern 225 foot pound max rigid torque wrench gun and I haven't broke any of the 3 bolts loose yet, so I guess I gotta go get me M.A.P. Torch, thanks for the good suggestions.

Thank You! The little plate under this particular bolt can move so the head isn't stuck at least not to the top of the landing (don't know about passenger side yet) and I also thought of the "drill a hole for the spray lube straw into the corrosion cavity" sounds like a really good option! I started a new topic here https://www.ultimatesubaru.org/forum/topic/186067-any-new-ideas-for-the-old-intake-manifold-stuck-bolt-problem/

93 Loyale EA82 SPFI Whilst replacing my water pump etc. I discovered another problem - the right side (by alternator) intake manifold is leaking coolant, which I suspected for a few years.. and the back long bolt is stuck / frozen - and so are the 2 long ones on the passenger/left side also... I soaked their heads and around the gasket (where we need really need it but probably can't get past the gasket) with liquid wrench and have to take care of other business so it will be a month before I can get back to it. Read through lots of good ideas for stuck bolts BUT these long intake manifold bolts have the head of the bolt more than an inch and a half from the stuck threads going into the head so I don't think many of those ideas will work. I'm thinking a 6 point impact socket, impact wrench and maybe first drilling a small hole into the manifold close to the base of the bolt, about a quarter inch above the head that I can load up with some fancy "nut buster" sauce, I have liquid wrench from 20 years ago but maybe their is something a lot better now? Here's some good ones https://www.ultimatesubaru.org/forum/topic/44039-what-are-my-options-with-this-stuck-bolt/#comment-354824

93 Loyale SPFI.. the back long bolt driver side intake manifold bolt is stuck / frozen - and so are the 2 long ones on the passenger/left side also... I havn't broke them off ( yet ) .. any easy way out? thanks all Craig

Well before I had to go on a "work furlough" to the east coast, I discovered another problem - the right side (by alternator) intake manifold is leaking coolant, which I suspected for a few years.. and the back long bolt is stuck / frozen - and so are the 2 long ones on the passenger/left side also... I soaked them with liquid wrench before I went to the airport.

finished the shimming, added more images https://www.ultimatesubaru.org/forum/topic/185922-shimming-water-pump-pulley-to-align-with-crankshaft-pulley-only-need-3-5-mm/ time will tell - but don't have time to be able put everything else back together and test drive for at least 3 weeks

Steptoe's, since my problem is neither the stock water pump height OR my timing belt cogs/sprockets incorrectly stacked or flipped I'm staring a new topic hopefully to help others with this different kind of a problem (and help my patience and sanity) and will paste in your good ideas.. I've painfully learned some more possible potential problems - but luckily not *the hard way* so far https://www.ultimatesubaru.org/forum/topic/185922-shimming-water-pump-pulley-to-align-with-crankshaft-pulley-only-need-3-5-mm/ Thanks Craig

That would have been good - before I installed & put all the rough stuff back together - 4mm would have probably been OK with a standard length shaft BUT it's a little "shakey" to go out 5mm with a stock length shaft cause the centering hole in the pulley won't be on the shaft, it will just be catching the tapered section right before the top/cut off of the shaft.. so I shimmed mine with 2 different washers to get a "safe" max height and want to make sure I get enough threads on the hub's studs, used one of each on all 4 studs - and used a micrometer to get all the heights the same - there is a LOT of variance in the thickness of washers even though they all came from their same packages. I put the larger one against the backside of the pulley , which is completely flat and th smaller on against the water pump hub, and got 3.6mm or .140" additional height and I think it will be OK, but not "perfect" in this image I lined up the (top) power steering center ridge with the (middle) crankshaft pulley center ridge , and we can see the water pump pulley center ridge (bottom) is still slightly offset. time will tell - but probably won't have time to be able put everything else back together and test drive for at least 3 weeks - unless my schedule changes again...
