Figit: To the best of my knowledge, the oil and water passages are like I've got in the pics (red = oil and blue = water). Someone PLEASE correct me if I'm wrong! It's possible the small round holes between the cylinders are coolant and not oil...

I thought crush was what you got after the bearing/cap/crankshaft system had been in use for a while. If I'm understanding you correctly, it's just the amount of distortion you get when the ends of the bearings are pressed together in the tunnel. Very interesting. I think all of this is...

Oh, you mean for measuring the tunnels! I meant just for measuring bearing thickness. For that I'm guessing the caliper style guage is sufficient? On second thought, it looks like there are attachments for the measuring anvils that give you narrower contact surfaces. Like these shown here

Snap gauge: Hmmm... Looks a lot like my micrometer only bigger. It still looks like it'd suffer the same issues my existing micrometer would, in that the measuring contact areas (called "anvils" for the snap gauge) are wider than the curve of the bearing surface. I'm still not sure...

Ah hah! Tunnels makes perfect sense and snap gauge I'll need to look into.

Tonight: Measured main journals and they're all marked 1 (Toyota stamp) except for number 6 (second to last), which is marked 2. The corresponding block/cap "cutouts" (for lack of a better term - if someone can tell me the real name, that'd be awesome) are all marked 2 except for 6, which is...

Wow Figit, that head gasket is nasty! That out of the way, let's see if I can answer a few of your questions: The bolts are definitely Toyota OE parts (unless someone else makes black head bolts) - But I think you already figured that out. Looks like the answer to your question about what to...

It's "mark" MK? ;)

Dude, crying here. That really sucks... Hopefully no damage beyond the BHG. I'd really like to see the head gasket when you tear back into it. I wonder if it was something other than a not mirror finish head that caused it.

Work's an excuse? ;)

Pics. Crank and bearing wear up close. Number 1 was pretty worn and number 2 had that single score mark (no corresponding mark on the crank that I could see though). The rest were just like 2, only without the score mark. In my mind, this looks like normal wear. If any of you engine...

I'm confused... But that's normal! I take it you learned a "tweek" from the master to get the rad mounted correctly?

Sorry, it's called "kelmet" for Toyota bearings.

Of course, I knew that! Actually, I had no idea at all... I remember something in the TSRM about Kynton (or something similar) but had no idea of its composition. Thanks for explaining that - now I know there's not some odd chemical reaction going on there!

Got the crank pulled tonight and am happy to report no other bearing issues other than slight copper coloured spots in places (bearings, not the crank). I'd still like to know what the copper stuff is - rust or minerals that end up looking like copper? No obvious scoring or abnormal wear...

Been trying to work that out myself. I also noticed the USB ports seem to be hidden!

Looky, looky - new toys! OK, so I'm easily impressed... Now all I have to do is learn how to use these and how to calibrate them (they're "seasoned" tools from my wife's grandfather).

Nice one!

He mentioned "Mopar CCC" and I think that CCC stands for "combustion chamber conditioner" although it could be cleaner instead of conditioner. Whatever its called, it's done an awesome job!

Yep, that's me! Actually I only said it because of the search thing. I tried to look up ASICS one night and couldn't work out why there was nothing to do with Toyota anywhere. It was only when I searched for "toyota variable intake" that I found out it was ACIS!
