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...

looks like 5mm would be optimal increase in water pump pulley height to be correctly aligned with crankshaft pulley BUT I'm going to go a little less - like 4mm so the pulley will still be secured by being (just barely) on the tip of the main 5/8" shaft of the water pump - at 5mm it's kind of loose cause it's is tapered by the top of the shaft .. and also the stock studs end up being too short at 5mm - (even with them turned forward in the hub) so 4mm height extension is my safest compromise I think. Here's the problem with water pump pulley on the bottom, crank on the top Of course I wish somehow I could have moved the crank pulley back BUT it only has barely 2mm clearance from the timing belt covers!..and I have my timing belt cogs on the crankshaft stacked in the correct order, so that's not causing this problem.. so I really need about 114mm hub / deck height - 4mm taller than the stock "tall" version, which is 110mm .. sounds like an easy simple job, right? .. as long and it stays together and the pulley doesn't wobble.. this solution by Steptoe's photos from Australia would probably be the best. https://www.ultimatesubaru.org/forum/topic/142209-water-pump-has-me-confused/page/2/#comment-1457136 but I'm hoping a "stack of 3 of these washers on each stud.." will suffice, cause I don't have easy access to any good metal shop tools and would at least want a good drill press and vice. https://www.homedepot.com/p/Everbilt-10-Stainless-Steel-Flat-Washer-50-Pack-800032/204276382 I found #10 washers at Homedepot that should work with a stack of 3 on each stud, going to blue loctite the studs & nuts. 1/2" O.D. x 7/32" I.D. x .049 thickness 304 Stainless steel - I just need to make the hole a little bigger and a stack of 3 of them is 3.81mm probably a safe compromise.. I'll add some pictures tomorrow if time permits and maybe Ill have the car back up and running in a couple of days - and hopefully the fan and the pulley stay happily attached.. will see.. If it starts coming apart then maybe try some 2" O.D x 1/2" i.d "fender washers" that could work if I open up the center hole to 5/8" and drill 4 holes for the studs - and I'd use 4 or 5 of the and it would be way more work and probably overkill.

neither did I - one "definitive marking" is the one closest to the engine has a "dot/punch mark" at 5.30 o'clock that you can kind of see in these fuzzy images. The rear cog is on the left, the 2nd picture is the pair flipped over showing the backside ... and the front cog his another notch /slot 180 degrees from the woodruff keyway. Gratefuly we can see both notches on mine (in my 1st image) so I must have them stacked in the correct order.. https://www.ultimatesubaru.org/forum/topic/66578-crankshaft-timing-belt-sprockets-the-truth/page/2/#comment-543849 Here are good images of the one closest to the engine, that has a "dot/punch mark" at 5.30 o'clock https://www.ultimatesubaru.org/forum/topic/139522-would-you-reuse-this-crankshaft-sprocket-ea82/ I found #10 washers at Homedepot that should work with a stack of 4 or 5 on each stud, going to blue loctite the studs & nuts.

Thanks Craig

I measured (again tonight) this water pump and it is 110mm hub height, as stated @ Rock Auto. so it's not what my problem is, Also discovered tonight that the crank pulley is maybe only 2mm away from the timing belt cover so I can't move it back/closer to the crank.. So possibly the best solution would be to pull/move this hub 5mm higher/forward (then it would have 115mm hub height) for it's pulley to align with the crank pulley ... or I could use washers but I would think it might be better to fabricate a spacer disk out aluminum - or buy one - I'd think someone may have made some for all the poor guys who installed a 105mm that really needed a 110MM? and to "lighten the load" on the bearings I wish I could find a "flex fan without a clutch, and I know many guys say dump the mechanical fan but I like good simple "fall back" systems in case/when the electric one fails.. Thanks Craig

Thank You! I think I got my crankshaft timing belt sprocket(s) in backwards, WRONG - they're OK ** after lots more research it seems I must have my timing belt sprockets/cogs stacked in the correct order, so that's not causing this problem. ** https://www.ultimatesubaru.org/forum/topic/66578-crankshaft-timing-belt-sprockets-the-truth/page/3/#comment-552982 my cog/sprocket with the dot at 5.30 o'clock is not visible because it's the one closest to the crank i.e. they're correct. it really seemed that my crankshaft timing belt sprockets were sticking out too far - but all the other images and videos seem to look the same as mine.. Craig

So maybe my crankshaft timing belt sprockets and pulley are sitting too far forward or something weird - or maybe it's been this way ever since I bought the car in 2016 - OR I messed something up and flipped a crankshaft sprocket when I did the timing belts & water pump in 2018. My crankshaft pulley is pressing right up against the timing belt sprocket and is held on with one big bolt (no washer) torqued to 140 ft/lbs. Also my timing belt sprocket on the crankshaft does seem to be sticking out bout this far (5-6mm) from the end of the crankshaft - although that seems the same as what I see in other postings and vids. ** after lots more research it seems I must have my timing belt sprockets/cogs stacked in the correct order, so that's not causing this problem. ** https://www.ultimatesubaru.org/forum/topic/66578-crankshaft-timing-belt-sprockets-the-truth/page/3/#comment-552982 Here are good images of the one closest to the engine, that has a "dot/punch mark" at 5.30 o'clock https://www.ultimatesubaru.org/forum/topic/139522-would-you-reuse-this-crankshaft-sprocket-ea82/ my cog/sprocket with the dot at 5.30 o'clock is not visible beacuse it's the one closest to the engine i.e. they're correct. this is when I was doing the timing belts in 2019, the crankshaft timing belt sprockets are circled in orange - and this is how they were when I started timing belt/water pump replacement in 2019. it looks like they are sticking out about 5mm beyond the end of the crank? Does that look right? other images and videos I've looked do seem the same Backside of crankshaft pulley 20240809 what got me Here's the misaligned pulleys ( unless Subaru INTENDED it to be this way? I doubt it ) **** EDIT 8/16/2024 2am I measured this water pump and it is 110mm hub height, as stated @ Rock Auto. *** so it's not what's causing this problem. *** Here's another great "zen art of Subaru maintenance" showing him pulling of these sprockets/gears.. both his "protection disks" are facing the crank, just like mine. https://youtu.be/QCnmC2gZahs?t=231 At first I was thinking that the pulley on the water pump I'm replacing is sitting about 5mm to far back compared to my crankshaft pulley - and it seems like I bought the correct 110mm hub height water pump as I explained in this post - in fact a solution would be to pull/move this hub 5mm higher/forward for the it's pulley to align with the crank pulley (then it would have 115mm hub height) Also discovered tonight that the crank pulley is maybe only 2mm away from the timing belt cover so I can't move it back/closer to the crank Thank You all Craig

So there might not be much value in the rest of this post except for the reference images showing the difference between the hub positions of the 110mm and the 105mm.. ========= Grrr, I bought what is supposed to be a "Dayco DP1081 Info Lobed Hub, Hub Height Approximately 4.320" +/- .020"; V-Belt Driven 110mm hub/deck height" from rockauto - and all 4 of their offerings are supposed to be 110mm ... Tomorrow all try to go over to where the car is and measure it.... like I should have the day it arrived.. BUT their pictures of the ones with 105MM hub height LOOKS LIKE THE HUB IS WAY FURTHER DOWN on the SHAFT.. So the one they sent me probably is a 110mm . https://www.rockauto.com/en/catalog/subaru,1994,loyale,1.8l+h4,1270178,cooling+system,water+pump,2208 and putting it all back together, installed radiator and put on my thin pulley (Hitachi inboard AC, non tubo) and it's sitting about 5 mm too close to the pump and doesn't line up with crankshaft pulley. Dayco DP1081 Info Lobed Hub, Hub Height Approximately 4.320" +/- .020"; V-Belt Driven below are a couple of images of Rock autos 105MM hub height (from 1988 GL) LOOKS LIKE THE HUB IS WAY FURTHER DOWN on the SHAFT?. https://www.rockauto.com/en/catalog/subaru,1988,gl,1.8l+h4,1268513,cooling+system,water+pump,2208 so maybe my crankshaft pulley is sitting too high or something weird - or maybe it's been this way ever since I bought the car in 2017 - OR I messed somthing up and flipped a crancksaft sprocket when I did the timing belts & water pump in 2019. My crankshaft pulley is pressing right up against the timing belt sprocket and is held on with one big bolt (no washer) torqued to 140 ft/lbs. BUT my timing belt sprocket on the crankshaft does seem to be sticking out bout his far from the end of the crankshaft. this is when I was doing the timing belts in 2019 so maybe I got crankshaft timing belt sprockets reversed or flipped - and it DOES look like they are sticking out about 5mm beyond the end of the crank? Backside of crankshaft pulley 20240809 Here's another great "zen art of Subaru maintenance" showing him pulling of these sprockets/gears.. both his "protection disks" are facing the crank https://youtu.be/QCnmC2gZahs?t=231 I'm pondering that I must have put the crankshaft timing belt sprockets in backwards when I did the timing belts & water pump in 2018 ... I noticed the gunked dried oil "teeth/notch marks" on the landing in the first pic below .. and in the 2nd pic the teeth are facing the crank's landing (it's probably wrong), in my pics above the "protection disk" that prevents the belt from coming off is facing the landing (on the crank) and that looks correct - but maybe each one is different and I stacked them backwards? this was probably the wrong way... and it was NOT reassembled (with teeth facing the engine) this way. otherwise I guess I need the THICK pulley, or maybe a short gear puller that can pull the hub forward and work just by pulling the radiator back out (to have enough room for woking the gear puller)? I've read about using washers and wish there was some kind of a single part spacer... I can't find this thick pulley here or digging around on the web.... I DON'T want to R & R this water pump. Thank you all
