I thought it was that or possibly some method of localised water to steam device. That's a long shot though - still it seems possible since the steam vent is directly overhead.

We'll have to wait till someone with intimate knowledge of toyota block design stumbles upon my thread I guess...
Yes, those metal stalagtite looking things are left inside from the casting. You would never know they are there unless you have removed a set of freeze plugs. LOL
They'll be leftovers from the CoreBox when they cast it.
Were probably used to locate the mold piece for the welsh plug holes.

Then they get bent up toward the steam holes to get them out of the way. Makes sense - and I was all excited about them being some sort of heat concentration device, used for localised boiling of the water for extra cooling (phase change from liquid to gas consumes a fair bit of energy)!
Pistons got cleaned yesterday and I took a couple of shots of them this morning.

Plans for the weekend
I don't have an exact tool (rifle cleaning kit) to clean the oil passages and just rang up a gun shop to see what'd it'd set me back. Sounds like $75 is about right... Not sure I've got that sitting around at the moment. However, I'm not sure I've got another few hundred to rebuild the motor if there's anything still in the bores and I destroy it!
- Plastigauge Rods
- Clean up head completely
- Test fit exhaust manifold to see how many holes need to be helicoiled
- Thoroughly clean out oil passages (yes, that means removing the crank again - DOH!!!)
- Finish bottom end

Last Night:
Picked up a box of goodies from IJ, as well as my brand new rods (well, almost) from Allan! You guys both rock!
Also experienced the "IJ special" pizza - not bad!
Today:
The rest of the previous list will hopefully get done tomorrow.

Today:
- Swapped old pistons to new rods
- Thoroughly cleaned out the tiny little oil passages from the oil ring groove to piston pin. Had to use a drill bit but it's now cake-free!
- Plastigauged all rod to crank pin - all pretty much dead on .040mm so in the middle of TSRM spec
- Removed crank, cleaned out oil channel in the block - no metal shavings, just oil varnish deposits
The rest of the previous list will hopefully get done tomorrow.
Really? That's quite surprising actually! I'll have to go check it out. If it requires an air compressor to actually work, I could be in trouble...
Spray gun cleaning kit made me think it was a cleaning kit that attached to a spray gun. You know, a tube on the end of the bottle brush to use the brushes and air pressure both. I re-read your post and realised the error of my ways. Sorry, massive brain fart!!!
I'm heading out to SuperCheap today so I'll see how it goes.

Today:
Spent the whole day doing all sorts of things but have only one piston/rod installed to show for it. Sometimes the best laid plans for the day just don't end up happening...

meeh i spent all day maken a template pipe about 3ft long 
and that filter part number is 15601-44011

Progress Report:
Got the other 5 pistons in last night!
Couple of pics:
1. "device" for getting pistons to 60 degrees in order to insert pin (bucket, hot water, thermometer)
2. "device" in action
3. assembled reciprocating assembly :biglaugh:
4. pistons back in block
Edit:
Removed first pic cause I need more space (and it was unneccessary).

Thanks! Might I just mention that those ring compressors suck! The one I bought was only semi-round and in order to get it to go around the rings the whole thing was so deformed it'd rotate the aligned rings when you'd tighten it. What a pain!
All good now though and the whole assembly is rotating with no more force that turning the harmonic dampener by hand.
Speaking of which, there are a couple of buildup howtos that mention not turning the components more than necessary. Is this because the assembly lube tends to find the oil holes and will work itself off the parts?
