That ring on the front of the cam is probably the mechanical fuel pump eccentric for the carbureted 22R, which is not used on the 22R-E. This was likely a conversion.

I thought the 20r was the only one with the mechanical fuel pump? Yeah that’s probably what it was then.
I just picked this up it’s insanely clean inside and appears to be 100% oem. Has a Toyota head gasket, full harness and dizzy and a bunch of sensors. Cross hatching looked beautiful in the cylinders and I didn’t see any over bored stamps on the pistons. No ring wash or anything. I’m thinking this has less than 150k on it and it’s out of a 93 or newer (oil sending unit and egr temp sensor)
22R had a mechanical pump, too. I think the cam was the same for both, or at least at some point superseded to all the same. If the part number is still on the distributer (19100-xxxxx) you might narrow down the year if you're that curious.
Congrats. looks nice.

oh okay I thought the 22r all came with an in tank fuel pump. That was definitely a 22r cam then.
pretty sure this one is pure 22re and 93 or newer. Has the new style oil pressure sending unit. Wires are oem Toyota and say 1989 though. It does have a slightly broken driver side timing chain guide. It’s got a factory DID Japan timing chain on it. I wonder if this has very few miles on it.
it didn’t have AC, I feel like I’ve seen that to have AC you need a certain timing cover, is this correct? My 4Runner has AC and I’d like to keep it that way.
for now I need to track down a timing chain/guide set, a 4wd oil pan and pickup tube, and decide if I wanna do a head gasket before I do the swap. called LCE today and pulled my spot in line for a motor. Sad but I think sticking with a Japanese motor is a smarter idea.
The 22R# was used extensively in other countries, so the basic block and head could be used anywhere, EFI or carb. That's why the USA models still have that block-off plate for the mechanical fuel pump well after Toyota quit having carbs on any models in the USA (1991).
That engine block will have the mounting holes for the AC bracket. The timing cover is the same, with or without. A few bolts for the cover get changed out to longer ones to mount brackets, but I can't remember if that's AC or P/S.
OSK makes a great timing chain set. The Achilles heel in most aftermarket kits is the tensioner. I saw a lot of cheap kits have the tensioner fail after a year. Painful. OSK has a tensioner equal to oem. There's a strong argument for using the plastic guides over metal, though i understand why metal is initially attractive.
Ishino Stone has a fantastic headset. In fact, I'm pretty sure they used many of the same vendors as Toyota. It may have an oil pan gasket, and I'd rec FIPG over an actual gasket. FIPG is just better.
22R# timing chains and head gaskets seem to have similar lifespans. If you have that engine on a stand i can't think of a better time to do one. If you do a chain you really should pull the head at the same time, anyway. I know some here love doing chains with the head on, but I think it's not a great idea.

okay I’ll look more into the bolts for the AC bracket.
im gonna get an osk kit with metal guides from 22re performance, I think the timing set in mine is the cheaper once cause the tensioner has been tired for the past 50k miles. I always have chain rattle on hot start. It’s REALLY bad if I only turn the truck off for 5 minutes.
it’s the newer style pan with the fipg sealant, so that’s gonna be fun to get off. It’s a 2wd pan so I have to swap that out. I’ll probably go to LCE for the pan/pickup tube/pickup gasket and get a tube of fipg at toyota when I go get gaskets,
im gonna go with OE Toyota stuff for all the gaskets. Whoever did the timing set before I got my 4Runner did it without pulling the head, it’s had an oil leak at those corners since I’ve owned it lol. I don’t wanna chance it. Junk yard told me they’d void the warrantee if I pull the head, but i doubt a junkyard is gonna honor a warrantee anyway. I’m gonna go get a stand in the morning and start tearing into it.
the thing can’t have many miles, cylinder 4 still has all the exhaust manifold studs in it!
timing chain is a did Japan and appears to be original. Has the factory timing gear and appears to be in brand new condition other than the edge of the timing chain guide being broken off.
cylinders look great other than very minimal vertical lines. Couldn’t feel them at all though. Cam looks beautiful, only finish wear appears on the tips of the lobes.
only weird things I’ve noticed is the vacuum distribution thing, forgot the name, had oil in it and the exhaust ports on the head are super moist with oil/carbon. Maybe this thing got rolled?
Cooling system looks like it’s seen better days, maybe cause it sat outside for a few months in a junkyard? Any tips on cleaning that out?
I would pull a main and rod bearing just to see if they are stock sized or may have been replaced. Plastigage for clearances and also do a compression check for the full health picture
