Bad news… engine possibly blown and looking for advice.

A detailed list of all work done and the costs ie: parts, machining, labor, etc (for future comparison) would be nice to see.
 
Another update...

It's been a awhile, but the shop has been diligently making progress. They got the "new" engine tore down in about 2 weeks after I dropped it off on MLK day. Everything looked great on the donor! Rod and main bearings were practically brand new. Piston rings were very dirty, as were the valves, but nothing abnormal for age. The block and the head were thoroughly cleaned. Valves were lapped, and new OE piston rings were installed. Oil pump was perfect and was cleaned. Timing chain was in spec. Chain guides were replaced with new OE. Water pump was replace with new OE. Block got a coat of black paint. Everything was reassembled with all new gaskets and seals. Short block was finished as of March 6, and I had the truck towed to the shop on March 9.

Short block was dressed using virtually all of the components from my existing engine. They flow-tested all twelve injectors and installed the best six. The blow engine had a lot of new components--P/S pump, EGR valve and vacuum modulator, etc.--all of which was moved over. The donor A343F was cleaned and got a new pan gasket. On Thursday, March 19, they informed me that they were getting the engine and transmission assembled.

The engine was installed earlier this week, and they are in the process of getting everything hooked up and reinstalled. Hopefully within two weeks, I will have the old gal back!

This is good because, unfortunately, my 100-series got totalled on March 11. Long story short, I got t-boned by a commercial vehicle and flipped on my side! Luckily I was not injured. Still working through a settlement with insurance, which is a bummer.

I'll post some pics when I have a bit more time...
Stoked to read that, man. Glad that everything with the 80 is working out… not so stoked about the new re: your 100.

I'll see what I can do!
 
Thrilled to have the old girl back! I was able to pick it up two weeks ago today, actually, April 9.

A few pics from along the way:

Regarding the total scope of work and cost:
Donor engine was disassembled, cleaned, assessed, and rebuilt. Gasket surfaces were all resurfaced and valves were lapped. Engine block was painted. Fuel injectors were cleaned and bench-flow tested. New parts included:
  • Piston rings
  • Full upper and lower gasket/seal sets
  • Timing chain tensioner
  • Timing chain guides
  • Water pump
  • PCV valve grommet
  • Plug wires
  • Spark plugs
  • T-stat and o-ring
Donor transmission pan was dropped, cleaned, and assessed. New parts included:
  • Fluid filter
  • Pan gasket
  • Speedometer sensor o-ring
  • T-case input shaft seal
  • Transmission rear seal
  • Transmission oil pump seal
Rebuild of engine and transmission took 40 hours shop time. Donor engine and transmission were $2,000.00. Shop time and rebuild parts were approximately $6,400.00.

R&R Engine/Transmission:
Remove blown engine and old transmission, strip to long block, and transfer most ancillary components to rebuilt donor long block. This includes the EGR system (new as of 07-25), PCV valve (new as of 07-25), v-belt pulleys, fan clutch (new as of 07-25), alternator, PS pump (new as of 07-25), PS reservoir, PS hoses (new as of 07-25), AC compressor, distributor, exhaust manifold and heat shield, intake manifold, and throttle body, all of which are newer/in better condition than the parts off the donor engine.

Radiator, upper and lower radiator hoses, and heater control valve (new as of 07-25) were retained. All other heater/coolant hoses replaced with new. PCV hoses replaced with new, including gas tank vapor hoses to charcoal canister. All vacuum lines replaced with new. All hose clamps on replaced hoses replaced with new. Throttle body boot retained (new as of 07-25).

Filled with ATF, 10w30 conventional break-in oil, and new Toyota red coolant.

Shop time for R&R was 40 hours. Shop time and install parts were approximately $5,000.00.

And, she runs great! I actually put 500 miles on her in one week, due to a lot of driving for work, and changed the 10w30 break-in oil with Rotella T4 15w-40. I've been driving it sympathetically while the rings seat, but the power and throttle response have already noticeably improved since I picked it up. I'm going to change the oil again at 1,000 miles.

While all seems to be good with the 80, my 100-series was sadly totalled in a wreck on March 11. Luckily I was not injured and I was actually able to drive it home after the crash, but I got t-boned and flipped over. I am in legal proceedings over it currently, so I won't comment too much, but its a bummer to say the least.

Sorry if I missed it but what machining was done to the head, valves, block, crank before reassembly?
Beside new rings what other internal engine parts were installed ie bearings ??

Sorry for your troubles !!
 
Glad you were okay! My son just totaled his 02 Taco (his second). I had a hell of a time with the insurance company, finally had to invoke my appraisal clause. I received 30% more for the vehicle in doing so after interviewing several appraisers (I can share mine if you would like). If you still have the vehicle, strip the upgrades you made if you can. Our insurance company wanted the bumpers on it (stock was fine). The rest could be removed.

No worries! I think I forgot to say!

Basically, they inspected the block, head, crank, rods, and pistons and blueprinted all of the bearing clearances. The main and rod bearings looked almost brand new and all the bearing clearances were will within spec. So, the bearings were all re-used in their original positions. Crankshaft journals were clean with no wear, and were polished.

Block and head decks were lightly resurfaced (not decked, per se, but mechanically resurfaced to remove the head gasket material and restore the surface finish. Likewise, the cylinder bores were checked for roundness. The bores still had the factory cross-hatching and were lightly honed just to clean them and ensure a consistent finish for ring sealing.

Then, as I said, the valves were lapped to the valve seats.

Pistons, rods, valves, valve springs, lifter buckets, etc. were reused in their original positions, after everything was checked and confirmed to be in spec.

Timing chain was inspecting and confirmed to be in spec. Timing chain guides and tensioner were replaced with new.

The "machine work" was done in house, so it is part of the shop labor charge. This shop builds a lot of race engine (mostly for Subaru rally cars) so they can do all of that in house.

That sucks. I am hoping that I can retain salvage and sell it to a local yard, as I will probably make out a little better.
 
After all the machine work did the shop wash the block, hot tank, run a brush into each port, compressed air, --- or how did they ensure the oil galleys etc were clean of debris before reassembly?

Parts washer, brushed, and blown out with compressed air, as I understand.
 
OK, sounds good.

The reason I asked is some manufacturers have seen engine damage from not cleaning out machining debris on new engines (not the FZJ80)

No doubt!

The shop that built it specializes in building endurance race engines--mostly Subaru and Mitsubishi rally cars and BMW and Audi SCCA cars. They do a fair amount of heavy-duty Land Cruiser, other Toyota, and Montero/Pajero off-road builds. They know what they're doing!

When I first visited their workshop after they got the donor engine torn down, it was hilarious to see my 1FZ crank sitting on a table next to these tiny Subie flat-4 cranks.
