Hot Tanking

When they do this at the shop, does that process work to flush out the fine rust sediment that has built up around #4 cylinder and the end block wall?

When people have had their block hot tanked/cleaned, have you also have them do the oil pan and transmission case?

If yes, how best to get the shifter cross brace out before hand? Or does one just leave it in?

Head Studs

The pics are of the head studs. The threads look like they had pliers used on them before I got the boat. Are these good enough that I can run a die over them to clean up the threads and carry on ?
The second pic is of the thermostat cover studs. On the right hand one there is a groove about 1/2" long on smooth body of the stud. This looks to be the area that would sit in the sleeve of the thermostat housing. So would it be ok?

Hate it when folks do that! That's exactly why the Snap-On stud remover is such a nice tool.
I think you'll be fine if you run a die over those threads. On reinstall, don't use a pipe wrench. At least, just jam two nuts together to seat the stud in the block. I install to 35 ft-lb - if there's a problem, find it as early as possible.
After the head is in place, use some lube on the threads and between the nut and washer. I use the silvery anti-seize from Permatex. Some black moly grease would be an alternate. Anything is better than nothing.

No need to tank the oil pan or transmission housing. Personally, I recommend changing the reversing gear cross shaft with the stainless one from our host. Do those two seals as well as the aft seal while waiting for the block.

Idler Spindle

The Moyer idler spindle remover worked like a charm. But, ummm, how do I remove the threaded portion from the spindle? I can't back it off with just hand pressure and I don't want to use anything that would damage it.

Idler shaft puller

Hi Greg,

Hopefully you didn't tighten the inside part of the puller too tightly, in which case you should be able to wrap some protective material around the spindle and hold it gently with a pair of vise grips. Thin cardboard, like a piece of file folder material should work. I always held the spindle on the smaller end that goes into the block so that if I ended up with any dings I could take a small file and dress that area up a bit. Don

Well I thought I put it on only finger tight.. but my assumption is the screwing down the outside section tightened the inside part.

I'll try the carboard on the THIN section tonight.

Note: upon reflection - I did not hold the inner screw steady with a wrench while screwing down the outside section- so it tightened it down the inner screw way too much.

Well that did work - using the narrower section and I did have to gently dress up the two spots.

ok on Monday I am taking the following into the shop (pardon my not knowing the correct terms here):

Block
- magnaflux test and from the result of that if good
- honing cylinders
- removing cam and idler bearings
- hot tanking
- prep/level surface? (letting me know how much removed in case need another head gasket)

Head
- Prep/level surface

Manifold
Pistons
Cam
Crank
- so they can measure clearances for me as I don't have the right tools nor experience for that. - need to provide specs from manual.

What am I missing?
- Should removed bearings be tossed or can they be reused?
- Should clearances be done before anything else but the magnaflux as the bearings will still be in for that?
- What else....

Take the reversing gear cover. Have them drill/tap the manifold side for the Kaminsky mod.

Right!
Forgotten about that one.

Alternator Fan Direction

Direct drive A4. Flywheel end I'm designating as "front"...

When standing at the "front" looking at the alternator, which direction do the aux drive and alt pulley spin? Counter-Clockwise?
