Do you plan on replacing your wiring harness as well?
I didn't see it on the list, but I only heavy-skimmed it.

Hey what's up Dirt! Let me know if you want to hook up somewhere nearby and do an 80 series run or even just meet for coffee.
Yeah I didn't go through the whole list but yeah I absolutely plan on replacing my wiring harness one of the first things I did was my EGR spot but you could see the things got warm.

ih8 scholar asks, ye shall receive.
Perhaps a bit premature to share, but I just performed my first break-in oil change at 520 miles flushing out 5w-30 OEM Toyota conventional for same spec Walmart special (Valvoline synthetic blend). So far, so good. No sediments in oil observed. Zero oil loss which is welcomed as I honestly got sick and tired of carrying around a quart or two. 13.3 mpg using regular gas, on 37s/4.88, LA congested roads. That's about a ~.8-1 mpg improvement over the og engine guzzling premium Chevron/Shell/76.
Q: Would I do the new OEM long block proj all over again?
A: Absolutely. I can tell in the past 50 miles or so the engine feels more languid and smoother to apply power. I'm hoping the 4.5L continues to stretch its Bambi legs as I take it easy to the next 1.5K/5K mile oil change intervals. Thereafter, I'll switch to the ubiquitous 5w-30 Mobil full synthetic.
Q: What are some things you'd do differently if mulligan?
A: I'd make sure to tell the machine shop assembler or whoever's working on the engine to take special care to clean up the iron block area that's covered by the timing chain cover. With a new OEM short block, there's a small chance you may have some casting debris, tiny iron bits, that may find itself swimming between the crank gear, oil pump gear and power steering pump vane gear (44316-60020). Even the slightest nick on these gears of any type may make an incredible noise that beggars belief. I didn't realize through all my hours pouring over Toyota engine diagrams that the power steering pump vane gear mates with the other critical engine gears and it makes sense since it's technically an ancillary part. IMHO, it's best practice to match new for new so make sure you get all new gears (3 of them in rotation) to go with your all new Toyota beautiful long block.
Only other thing is order parts all at once from a USA parts counter. I didn't have a comprehensive list I could reference like this thread. Now I know if I were to do it again I can do it one stop shop. There was no part as I can recall that I ordered from the Middle East that wasn't available via Toyota USA. I like to support my local Toyota parts peeps as I value the relationships built f2f.
Q: What's your most pleasing observation post-rebuild?
A: If not the engine feel/perf over the fullness of time, I'd say it's hands down the new power steering box. The old box was still tight for a 25 year old, but I could feel demonstrably improved tightness in steering motion off center with the new box. I know the FSM allows for some degree of slack off center, but the best way I can describe the change is there's more resistance even in the FSM prescribed margins if that makes any sense. There's no loose steering motion any place in cycling through the steering operation. The steering box was the last mile as epilogue to Delta 4 arms, all new OEM suspension rubbers and tie rods.
Q: If you wanted to find areas where you could reduce spend, what does that look like?
A: If I had a trustworthy 1FZ-FE assembler, I would reuse the og short block ($3500+). I'd reuse/refresh rather than replace fuel injectors ($900). I would consider reusing the cam shafts ($1K). I'd refresh the steering box, but then there's nothing like a new OEM box (net $1K). There's $5-6K right there you can shave off from a completely new OEM block and still have a delightful powerplant.
Anything else?
Don't forget the igniter and coil (89621-26010 / 19080-66010). I wish I nabbed a Toyota OEM reman transmission a few years ago when it was still available. That would've been dreamy to mate it to my new engine.
All the new OEM body mounts and related parts are still gathering dust in storage. I didn't get around to it.
I hope this helps!

Ahh, good call, I ordered a couple knock sensor wires to repair my harness with a much better splice from @NLXTACY .
I can just see it acting up on a family trip this summer and trying to figure out what's going on on the side of the road, no thanks always focused on reliability and preventative maintenance to save the headache.
I'm going for the NASA solder with clear heat shrink sealed ends for the win on that Wits End wire knock connection.
I definitely plan to get a new harness when I order my short block.

I'd be curious to know if what Joey has in his stash is the made in Japan variety. I know there have been reports of more recent harness orders being sourced out of Vietnam. I have zero concerns so long as Toyota OEM, but would snag the Japan set over Vietnam if given the choice.

That's a great point never in a million years would I imagine Toyota would be making parts OEM and Vietnam. If it's stocked by @NLXTACY that's good enough for me I know it's rock solid
I remember for the fusible link the PO cut my harness on the truck side and I was able to source a factory replacement connector and wire. I thought about doing the same for the knock sensor when I saw the crappy splice by the PO but then I was browsing wits and clicked easy

No china on my Rig, no thanks

I can't tell from the pictures did you ceramic coat parts of your engine?

No, I kept everything og.
5/3/22 update:
3K miles on the new long block as I type.
- No lights on the dash (did an EGR/VSV overhaul as part of engine build)
- Zero oil consumption
- No oddball noises
- Mixed urban LA jungle driving
- Most miles accrued from a roundtrip visit to Cruiser Outfitters which has something like 3-4 passes to climb and descend (6K feet above sea)
Steady as she goes!

82121-60343 (listed on 1st thread post)
Strongly recommend replacing with new. Nothing broke, could've reused, but mine was understandably crispy.

I'm in the final phases of my head gasket slash full refresh and am very happy I chose to replace the wiring harness.
I also pulled and rebuilt my transmission harness it's all freshened up
I'll now be able to enjoy my rig and slowly build a new engine over the next year or two

Sorry if it was listed somewhere in the thread, maybe I missed it?
What all is included in the engine kit 04111-66036?
All I can tell is from looking at pictures online: HG, valve cover gasket, intake manifold gaskets, exhaust manifold gaskets, oil cooler gaskets, and the rest of the parts are too small for me to eyeball from the pictures.

9K miles on the new 1FZ-FE and 5 oil changes later, I'd say it's fully broken in.
No lights. Zero oil consumption. No leaks I can see. Picked up power since my last update at 3K based on a recent LA-Seattle-LA road trip. Up the Grapevine Southbound at 80mph+. Can set cruise at 85mph pushing MT 37s keeping up with them modern buggies on I-5. I can think I can hit 100mph.
Performs like a new Toyota engine should. Enjoy yours!

Awesome! Congratulations!
My 1fz refresh is running great, I received my ARB snorkel today, my stomach hurts and anticipation of drilling all those holes
Looking forward to landing a short block, head, and cams to begin the "new 1fz" project.

@NLXTACY has everything you need in a kit. The photos are better as well.
Yes, I'm looking at the Wits' End packages as well as dealer parts. Right now I'm just trying to figure out what is included in the Toyota part# and what might be missing.
So, again, just going off the picture, 04111-66036 I see:
intake manifold gaskets, exhaust manifold gaskets, tb gasket, HG, oil cooler gasket, valve cover gasket, water pump gasket, valve stem seals, fuel line orings, injector orings, front main, rear main, dipstick oring, and I can't really tell what else I'm looking at.
Also looks like it does not include:
spark plug tube seals, studs/nuts. Can anyone confirm?
Do the spark plug tube seals need to be replaced any time the valve cover comes off? I did mine maybe 20-25k ago.
