This Weekend:
More not so fantastic news. Got all the pistons out and discovered 6 was on the verge of being spun (unless my definition of spun is different to reality - hey, it happens). The rest were either heat deformed and full of deposits, or just full of deposits. The stuff on the bearing surfaces looked a lot like copper. I thought it was rust at first but upon closer inspection, it really does look like copper. No idea where it'd come from though. Perhaps it's a composition of a few metals that have combined under the heat/oil/pressure environment of the engine.
Either way, I'm starting to wonder if this is still going to be an affordable rebuild, given the items that will need to be milled/replaced.
So far the list is:
I'd also be silly to assume the main bearings are going to be re-usable (in fact, I never assumed that'd be the case and probably would have replaced them even if they were spotless).
This might not be cheap, to say the least!
As always, your thoughts are welcomed!

So far the list is:
- rod bearings
- cylinder bore/hone
- crank machining (or polishing at least)
- O/S Pistons
- Rings (oversized or otherwise)
- plus any head work that needs to be done

A few more of the groove worn into the rear of the crankshaft from the rear main seal, some of the "good" bearings (no shots of the only one that wasn't heat stressed, deformed or had deposits), pistons, and crank.

Micky: I can machine the Rear Main Seal housing so the lip of the seal sits 1mm further back I did this on mine this time as the crank has the same groove.
That's an awesome offer Ian! What's CNC bench time cost these days?
You reckon the groove is more of a problem than that rod pin on the crank, or the scuffing on the rod and cap?

I keep thinking all this stuff is crazy expensive. Couple of quick questions to set me straight:
Sorry for the n00b questions but in this case, that's precisely what I am! Ian, I know you've got your favs and my gut tells me they're not going to be the cheapest - still I'd take your advice very readily when it comes to this stuff!
Anyone else has any experience here, please let me know.
TIA
- Do you have to grind all rod journals down at the same time or can you just do one?
- Is there a typical cost I should be expecting on this sort of work or does it vary like everything else?
- What sorts of questions should I be asking potential machine shops to sift out the good from the bad ones?

Been trying to clean that garage out for months now. I'm afraid there's not much else to get rid of! Still, you never know...
If I'm not mistaken though, isn't there a few items resembling a car attached to that 7m-gte?

only for as long as it takes to pull the fuel tank and then place bricks before the cutoff saw makes it .5 of a car
