Nice!

I'll tell you what, as a 56yr old stuntman, "YMMV" is very germane...

HAHA

Jugs removed, hopefully, will find replacements...

Piston pins seem to want to stay firmly where they currently live...hmm

Do you wet torque all of your stud threads or just the through bolts on reassembly?

And it also shows how difficult a photo only analysis is... no depth perception, glare, etc.

That is outside my scope of work. The case will go to Divco for recutting the mount and inspection, honing. The balance of parts to Aircraft Specialties and hope to get the parts back within a year...?

I will have it reassembled by a professional. But getting it apart without damage is in my wheelhouse...haha

So the rod bearings are a mess, it's a good thing I took this motor all the way down.

I thought I had all the rods photo'd but clearly not. Only one was clean and unscarred.

Crank didn't look near as bad as the bearings but it will need some attention for sure.

I can't help but wonder if Barrett will do the rebuild... after all, they share the same driveway with Aircraft Specialties. Hoping that's the case, no pun intended.

Only rod bearings shown not mains. . ..
It looks like a main bearing spit debris (what do they look like?) into the oil stream and to the rod bearings. The main concern for the crank is wear.

Agree you are fortunate (very) to have taken this all the way down. The harsh scaring would have lead to catastrophic failure and likely throwing a rod. Now the oil cooler has to be replaced/rebuilt. It started somewhere, better follow it to a source and understand it.

Maybe it's just me, but I like reading the story an engine presents when dissembled. Like reading a book with lots of threads and events. Oil, bearings, piston/ring/barrel wear, colors, gear contact and more. All the weaknesses and history revealed.

Same here - unfortunately sometimes the story does not have a nice ending, but we can certainly learn from it.

I need to go back and re-shrink those pics, somehow they didn't take my resizing...
