The following are things to consider if you are thinking about rebuilding your 3RB or 3RC engine.
The two failure modes that I have seen with the 3R# engines are (1) the top of a piston will break off, and (2) the fiber timing gear will crack in a circle around the metal that press fits on the camshaft.
I believe that the stock color of the engine (block, head, plate at rear of head, pan, steel side covers) was black on the Corona and gold on the Stout. The valve cover, the timing cover, and aluminum side covers on the earlier engines should be glass beaded and clear coated. Add a new decal (3R, 3RB, 3RC, 5R are all in stock) to the valve cover before cover coating.
For those that want a factory remanufactured engine with a warranty, figure $2000 + shipping & core charges, contact RAM Engines in Spokane, WA, 800-233-6934 and talk to Jack or Greg Bunton (the owner or his son) or to Ken McGuire in the shop.
Generally oil pumps are OK but they need to be disassembled, cleaned (carburetor cleaner works), checked per the specs in engine manual, and, if OK, reassembled with a new gasket. In many full gasket sets, the supplied oil pump gasket is too thick. Make sure the gasket is very thin, about 0.05mm to 0.10mm (0.002" to 0.004"). New oil pumps are difficult to find but I have a few without the screen $119.50, and maybe one with the screen $151.25..
The following are the typical minimum parts required to do a good rebuild. All parts are NT=aftermarket unless shown as Toyota.
1 04111-40048 overhaul gasket set NT $88.67
Toyota set $164.22
1 11011-43010 crank thrust washer set std $12.01
1 1170x-40020 main bearing set note 1 $61.24
4 1310x-40010 piston with rings & wrist
pins & clips notes 1 & 2 $38.47 each
1 1320x-40021 conn rod bearing set note 1 $38.25
1 11802-40010 camshaft bearing set std $38.33
1 13523-TGSET camshaft timing gear set, steel
crank gear, aluminum timing gear $69.50
[Sets with fiber timing gear, Toyota and
NT also in stock]

note 2: Normal rings are steel because they break-in better. If you want chrome rings specify and I will supply if possible.
Other parts as required:
90999-73046 pin bushing set $21.50
--Very few stellite valves or good used, faced valves
are in stock. If your engine will be used 'gently'
and not often, steel valves will work fine--

NT iron $2.40 each, brass $3.10 each
11462-40010 cylinder liners $17.75
13411-40011-84KIT crankshaft kits $175.00
13411-40011-84 crankshaft, reground
std or 0.010" $75.00
10 90201-12118 flat washers for head bolts $0.63 each
1 90404-16160 union for later (shorter) temp sensor
new $6.72, replated $5.03
1 12180-13010 oil filler cap, round Toyota $10.97
2 90250-08054 guide pins manifold/head $0.91 each
2 90116-08038 bolt, stud long rocker arm thru valve
cover replated $4.50
1 90345-51025 plug, front oil galley side unplated $2.34
1 90404-14013 union, bypass hose replated $6.75
4 9034x-splug-1415p plug, air injection ports in
3RC head $1.37 each
The following kits are for those that want to make the engine look more like a new engine might look from Toyota:
The 01 & 02 kits include a refurbished valve cover (that has been blasted, has a new decal, has been clear coated, has a replated ventilation tube, new grommet & has tube mounting hardware), includes nuts & washers for top of the valve cover, includes bolts for the plate at rear of the head, includes bolts & washers to mount timing cover, includes bolts & cup washers for push rod covers, includes bolts for oil pan to block & oil plug, includes refurbished oil dip stick for those with dip stick tube in side of pan, includes the water drain thingy, and the ventilator tube s/a used with the PCV.
The 03 & 04 kits delete the refurbished valve cover but add the decal, replanted ventilation tube, and associated hardware for those that want to blast & refurbish their own valve cover.
12000-DUK01-3RB basic dress-up kit 01 for the 3RB $40 core $165.00
12000-DUK02-3RC basic dress-up kit 02 for the 3RC $40 core $165.00
