I would bet this IAC valve is the original from factory.

Has anyone actually opened up their 22RE IAC valve and cleaned it, sealed up the cover with some kind of gasket maker, and reinstalled it, and it worked 100%?

Thanks,

Gnarls.

Yes, for awhile........

Test the resistance across the connector.

I also had to rebuild the harness connector as the wire(s) broke internally next to the connector.

I cut it off, fixed connector with new wire, and reconnected my new pigtail to the original wires.    Polarity of wires doesn't matter for this application.

Test the resistance across the connector.

There is zero ohms across both terminals at the connector.

I'm glad I did NOT apply any solvent or liquid on the inside of this IAC valve.

After I cleaned some of the carbon off with only a dry Q-tip, I noticed it looks like there one piece (attached to spring) that is made of some kind of phenolic material.  The cover is also made from what appears to be some type of phenolic.

I cleaned the 2 nipples with a tiny wire brush and my Dremel tool.

The old gasket is still intact, so I will just apply a very thin coat of Ultra Black.

I'm not sure what level of functionality it has at this point, but I will re-install it a see.

I ordered my 4 hoses and new clamps from 22RE Performance and should be able to get this re-installed by Saturday morning.

That's too low, it should have some resistance.

Use some jumper wires and see what happens (after checking continuity at lowest setting) and power it up..

Should get hot and the bimetallic strip should change opening.   (leave cover off)

Find the write up I told you about.
Everything will make sense then.


I checked it again this morning at 77.3 d F in my "study".   I got 00.04 ohms

I put it outside on the patio with ambient air temp at 61d F.  I checked it again after 30 minutes and got 49.7 ohms.

So is the measurement correct?  For a wire, resistance (ohms) goes up with increase in temperature – not down.  The gate did move to allow an opening very close to what is diagramed in the FSM... so it appears to be functioning properly. 

The FSM is not clear on measuring the resistance - 39 to 59 ohms (at what temperature?).  In the FSM, the resistance measurement is No. 2 under "On-vehicle check", and after checking and pinching air hose while engine temp is below 140d F, then again after warm up.

I think I understand how this device works. It’s mechanical.  It is simply an air “gate” to allow more air into the chamber at cold idle – when the mixture is rich, increasing engine RPM.  After the engine temp goes up, the heat coil heats up from the hot coolant being pumped next to the heat coil, causing the bimetal strip to expand and twist, which moves the phenolic gate and then closes off the air opening.

After the engine is started, the ECU senses current flow through heat coil, as the coolant heats up, and the bimetal strip closes the gate - lowering the engine RPM.

So far, I can’t find a video or write up that tells me what I want to know?

The coolant alone doesn't move the bimetallic strip very much.

The wire is resistance wire.    It heats up the bimetallic strip..........


0 ohms sounds like a short..........

Oh... OK.  I thought the ECU was measuring resistance.

So, the heat coil is heated up from the current that the ECU sends to it at start up - which causes the bimetal strip to twist or bend and close the gate.  I assume the two nipples attached are to flow coolant passed the chamber to keep it from over heating.

So there must be current applied to the heat coil constantly during the time the engine is running.

A short can measure zero ohms.  But since I got a reading of 49.7, could there still be a short?  If the coil had an open, then the ohm reading would be inifinity, right?

1) yes
2) yes
3) if you can measure 0, there's a short under certain circumstances.   Make sure it's not you causing short
4) correct

UPDATE:  3-15-2017

I should have my hoses from 22RE Performance on Friday.  Saturday morning I should have the engine ready to fire. 

From race engines to antique engines, over the years I’ve had conversations, read, watch videos, about different procedures, recommendations, suggestions, practices, advice, and hot tips on how to break in a rebuilt engine.

I am curious if anyone has learned of,  or has experienced a successful procedure for breaking in a rebuilt Toyota 20/22 engine, and would like to share that.

Since I’m hoping to fire my 1986 Toyota SR5 XtraCab, 5-speed, rebuilt (from block up) 22RE on Saturday, I would appreciate any suggestions, comments, or advice.

Thanks,

Gnarls.

Finally got my hose coolant bypass hose kit from Putney.  I tried to make regular hose to work.  Was a little broke for a couple weeks.  But I finally got all the little coolant hoses.  Hopefully, I can have them on tonight.

For breaking in the engine, drive it live you are breaking in new gears. Do it on back roads so your speed in never constant.

I have never broken in any gears... I will drive on some back roads out here in the desert.  I will vary the speed.

It takes forever but for the first 500 miles, drive for 30 or 40 minutes at a time. stop and let it cool down. Use cheap oil for that first 500, no need to spend good money on something that is going to be junk in a few hundred miles.

Yes, from normal operating temp for short runs, then complete cool down IS the way I plan to break in my rebuilt, and is actually more important than varying the speed.

I plan to run the Royal Purple break-in oil for about 100 miles, then drain with new oil filter then put in 10-40 conventional for the next 400 miles, then drain and run another 500 miles on conventional. 

I will not be babying it.

UPDATE:  3-17-2017

Just some thoughts about tomorrow when I hope to fire this rebuild….  about 9 months after starting. :blah:

I received my IAC hoses and clamps yesterday. :D

When I started this project there was no rush.  Since I can’t do things half-a$$ed, I knew I’d be spending time and money to do it the way I’d feel good about it at the end of rebuild, AND I knew it would be a continuing project (exhaust system upgrade, camshaft changes, dyno testing, lockers, Marlin Crawler t-case, etc). :driving:

Having spent many years maintaining older vehicles, I also knew replacing old parts was part of the deal. :yesnod:

I underestimated my out-of-pocket cost and my actual hours spent from start to finish by quite a bit. I’m now North of $4,500 in cost.  I didn’t track my actual hours, but the total will be more than 200.

I’m not complaining about having to replace a 30 year old rubber hose because it is actually amazing to me how well those little Japanese Toyota engineers designed this truck!

As anyone who has purchased Toyota factory parts knows, the Japanese are REALLY proud of their parts! :smack:

$54.00 for one little rubber hose seems outrageous!  :yikes:

Not to discourage anyone who may be new to doing this type of project, just be aware of potential costs for parts.

Here are my new hoses and clamps – just for the IAC valve connections….  $136.50  :shudder:

Gnarls.  :spin:

I just got the 3 pack of hoses and the u shaped one for my 2nd gen, and it was $74 including shipping!  I tried to find local and elsewhere.  But no winning on that one. 

I wanted to get it put on 2 nights ago when they came in, but family had to come first.  Hopefully this weekend, after we get back from a overnight adventure to Astoria, OR.

Yeah... I'm very familiar with the "family had to come first".   :thumbs:
