93 22re Intake manifold removal ??
Removing my head and therefor gotta take off the intake manifold. Just looking for the easiest way to accomplish this. I tried to split the manifold in two, upper and lower but find they stick together rather well. I was wondering if it is even worth wild to split it or if I should just try to pull the bolts holding the enitre manifold to the head? Any tips or comments on intake removal will be apprechiated. Thank-you.

be mindful of the "hidden bolt", there is a bolt on the lower intake that is recessed and hard to find. It is an alan head bolt near the front side of the intake under the fuel rail.

x2 on this, I believe it is right under the thermostat house. It is a long bolt too. Split them, they seem stuck but they will seperate.

I'm trying to remove my intake manifold as well, got the top and bottom off but the wiring harness going down the tranny goes in between the lower manifold, is there some sort of connector on top I could remove instead of taking several connections down tranny including the 02 sensor?

22re wiring harness that passes through intake manifold
I'm trying to remove my intake manifold as well, got the top and bottom off but the wiring harness going down the tranny goes in between the lower manifold, is there some sort of connector on top I could remove instead of taking several connections down tranny including the 02 sensor?
Next, how long do those O2 sensors last...?
Thanks All. Great forum for the 22re and having fun working on it. Seems straightforward - front end all rebuilt and working [I couldn't resist firing it up once more to find head gasket blown]. Looking for gasket kit and probably OEM head gasket and maybe studs instead of bolts; but, after reading, looks like reusing bolts works just fine with the appropriate alignment bolts. Appreciate all tips - still in research mode before I move forward with cylinder head fix.

Head gasket set on the way - starting on clean-up/prep work on all of the gasket surfaces and bolt threads - the head is already milled. Looks like they took off around .027- .030 by a carpenters square [I don't own calipers].
After I have prove this 22RE will run, I plan to buy engine stand, cherry picker, and a few more tools just for rebuilding 22re's. For now, I am on the cheap.

I haven't started cleaning yet I stopped at the timing chain. I'm also gonna clean the inside of the intake manifold and head cause they are caked with soot and oil. I'm hoping to finish everything when I get back from leave. Hopefully my buddy will work it. Only have 2 days to work on it then I leave for Korea but I will def post up what I experience. I'm really not looking forward to installing the vacuum lines since I'm missing some and there are already soooo many.

Timing chain tip: Don't forget to zip tie the new chain to the upper sprocket - this will keep you confident that timing is still set correctly - even after you remove the head assembly.
TIP: During re-assembly of head to block, if you put the hot return pipes on the head before setting the head assembly on the block be careful not to damage the head gasket in the rear left corner - I dinged mine a little and hope and prayed it would not leak when I set the head. It was the outside corner so I think I got lucky because it's not leaking. Leave the bolts on the hot pipes loose so that they can be adjusted when you are setting the head on the block. Most importantly, don't forget to torque the head bolts in order specified in manual.

U need to take it off from the xmns, than pull it through the intake manifold to take it off. Take your time. Besides the connectors you have the wire harness hold downs spread throughout the harness. I use plastic wire ties to secure the connectors to the wire harness so it doesn't flop all over the place while pulling the wire harness through and around fuel and brake lines and the intake manifold. I also tied a piece of string to the connector that connects to the o2 sensor before I pulled it through across the top of the xmns. Untie the string once u get the connector through and leave it. U r gonna need it when reinstalling the wire harness. I'm currently trying to remove my intake manifold from a '92 22Re. Gotta go look for the Allen bolt that WILIE TOYOTA talked about in his thread.

Hey all, I know this post is old, but I just started a head gasket job on my 94 4Runner and it's been a challenge. Your advice here has helped me through a tough spot in the job and I wanted to thank you all for your advice because I'd be pulling my hair out without it.
Take care!

Looks like I may have spoken to soon...another tough spot, but at least I'm going back together at this point. If you can advise on this, or point me to the correct forum I'd be most appreciative. SO, front cover back on, head torqued down to correct spec (58 lb. ft.), and I CANNOT get the cam sprocket back on the cam. I am, and I hate the overuse of this word, but literally, within 1 mm of getting the thing on. The nk pulley is at zero and the notch in the sprocket is too. When I put the new guides and tensioner on, I moved both guides inward as far as they would go after releasing the tensioner. My Chilton manual was completely vague on the procedure and the instructions that came with the chain were as well. I'm virtually certain I didn't slip a link down below. What did I do?
Again, thank you for any/all advice!

Found the problem! When I replaced the timing chain guides, I adjusted the passenger side guide to it's tightest setting (moved it toward the middle of the engine as far as the slot in the adjuster allowed). This, apparently, leaves you about 1 mm shy of being able to get the sprocket on the camshaft. I used a flex-head wrench to loosen the adjuster bolt and let the guide "relax". Then I tightened it and the sproket popped right onto the camshaft.

Temp sensor
same here slow to start in the morning. Turns out the wire connector had come off of the green temp sensor on the front of the manifold. Put back on and starts right up every time now. When this happens or if the sensor is bad the computer doesn’t know the engine is cold and won’t fire the cold start injector.
oops! Wrong thread.
