That is the way I've done it with no problem, if the alternator bolt does loosen, then torque it up while holding a spanner on the crankshaft. A lot of people only have hand tools so an air impact wrench isn't an option for the crankshaft bolt.
Haven't been round to the garage to confirm, but sure the setting for the crankshaft bolt is around 50 lbft, but will check tomorrow. I know I had to buy a new torque wrench as my other one only goes up to 40 lbft!

Since the alternator/stator turns the opposite direction of the crank, you can put a wrench or socket on the alternator/stator bolt and it will hold to loosen the crank bolt. However it’s a little smaller in diameter and could snap. I’ve done it that way with no problem, but there’s no guarantee it won’t snap.

The trick is getting the crank to torque tight to spec again. The alternator bolt will loosen when you try to torque the crank to spec.

The clutch will slip if you put it in gear and apply the brake. Rope in a spark plug opening works if the heads are on for loosening or tightening.

An impact gun, hammer , or the bingo method are good choices to avoid breaking things.

I never tried it, but I guess hydro locking it would work too.
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

Torque spec on the crank bolt is 36-40 lbs-ft.

Thanks. A quick zip with the impact loosened the bolt. With the corrosion that's in that area from no drain holes, the inside pulley is stuck so I hosed it down with PB and will pick up a pulley puller tomorrow. Everything else looks good so far. Pistons come out flush all around so no bent rods. I'm going to order the gasket kit and belts from Randakk and do the main crank seal since it seams to be leaking. The upper head bolts on the right side have some corrosion so that's kinda weird and there's one spot of weird sludge on the same side where the internal hex bolt is so I'm going to have to take a look at that

Man that is ugly. Rust on the rocker arm like that is rare. Unless it sat with the valve cover off. :o

It's strange for sure, it's on the three upper head bolts and that forward rocker arm, right head only. The left side looks great inside. I know for sure that it sat with timing belt area about half full of water for IDK how long. I'll start cleaning and doing further evaluation on everything tomorrow night.

Started cleaning the heads last night. I'm going to pull the valves for a quick look. I discovered that the internal hex plug that was surrounded by milky goo (pics above) on the right head was only finger tight. This leads me to think that it loosened and backed off a hair and was allowing a tiny coolant leak since that plug is to the coolant chamber in the heads. I'm thinking its the reason for the strange corrosion on the upper head bolts and the forward rocker arm as well since moisture (coolant) was trapped in that area for however long. Anyone ever pulled those plugs before? I'm going to have to find a torque to put it back in. Everything else is looking good so far. No crud or deposits in the coolant system, some oil sludge in the bottom of the engine but it has been sitting.

I don't remember that there is a torque setting for those plugs. They do need a sealer on them though. Then look carefully around the area surrounding those plugs. I've seen two different heads that were cracked in that area. Almost missed it the first time. Hair line crack was hard to see. Have to get the heads clean before inspection.

Silly question but are those plugs on all GL heads? Didn't notice them on mine, (1980 1100), when I last had the heads off so certainly didn't check them. If you do take them out for cleaning, what sealant do you use, and what are they actually 'plugging'?

1000 yes. 1100 heads I don't know. They are casting holes that were just plugged that way. Any sealant that will seal out water and stand up to heat.

Well I'm glad that I decided to open up the heads to catch that leaking plug. I'm going to seal them all just to be safe, lucky the coolant didn't go far from around that plug area and mix in with the oil.

There was a slight oil leak on the left side of the front cover so I decided to pull that too. The coolant return on the same had started to leak through the internal part of the cover gasket and had filled a small cavity but hadn't mixed.

One question... is this the standard water pump impeller? It is made of a what looks like a phenolic material and the ones I see online are metal.

That is a phenolic material and the original one possibly from new . The replacement ones are now a metal impeller as you see offered for sale. Nothing wrong with the old style design. I would question the inner workings though given all the other corrosion you have encountered. The down side is they are not cheap to replace with a new one, so if there is no noticible play in that one it maybe worth giving it a try before a replacement is ordered.
