Quite the inspiration there Matt; that's whatcha call a proper teardown. <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />

On the AC, you'll want to drill your two holes for the lines thru the firewall while you have all that stuff out; measure twice; cut once; wear safety glasses! <img src="/forums/images/graemlins/cheers.gif" alt="" />

Body Damage is Cool
I bit off a big old hunk and I'm a chewin away! <img src="/forums/images/graemlins/lol.gif" alt="" />

I'm gonna need 3 maybe 4 new firewall holes. Two for the AC refrigerant lines. One for an evap housing condensate drain line. And another for the ECU harness. I thought of going at it with holesaws, but I'm gonna look into getting some of those screw drive, sheet metal cookie cutter things that electrician's use to punch holes in big electrical boxes.

Kewlynx, you'll probably be able to appreciate it when I tell you that I'm doing much of the work in the great out-of-doors. It was about 10 degrees when I quit tonight. Might be -2 overnight! But not to worry, temps in the mid teens forcast for much of next week! <BTW> I've been using a propane torch to warm stuff like hoses and plastic clips before I pull on them because they have a tendency to break easily at these temperatures. Well today reality intruded and a failing flame reminded me that propane stays liquid a 10 degrees F. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Thanks for the kind words. -- Matt

Body Damage is Cool
Hopefully, I'm closing in on the home stretch of this project. I have a new fuel tank in place. Glad I bought it when I did (last fall) because it was around $159 back then and seems to be selling for $225 now!
[Linked Image]
I installed the pump I salvaged from the 4runner donor on a new pump bracket from Toyota and installed it in the new tank along with the fuel gauge sender from my '84's tank. I made a new fuel delivery line out of 5/16" high pressure fuel hose and salvaged metric fittings from the 4runner's damaged fuel line. I am using the '84 truck's original metal fuel delivery line as the new fuel return line and the original vapor recovery line for its original purpose. That and a new fuel filter rounds out my fuel storage and delivery system work.

I also cleaned the thick carbon deposits off of the piston domes. I had much oil leaking through the valve guides on cylinders 1,2,3. I suspect that this was the source of the carbon and of the minor pre-ignition pinging. I even polished the domes to look like new pistons. I should really have taken before and after pictures. <img src="/forums/images/graemlins/frown.gif" alt="" />

I've made progress in the wiring area as well. The dashboard part of the chassis harness is in. I did extensive mods to the side body branches of the chassis harness that run from the front of the dash area to the rear of the vehicle. The 4runner harness has much more circuitry than a pickup. My pickup had almost nothing running down the driver's side. The 4runner has a lot wiring for the rear power window and window defroster on that side. The 4runner also has separate tail, brake, license and backup light wiring for each side of the vehicle, whereas the pickup ran all that down the passenger side along with the fuel gauge wiring. I was able to get rid of much of the driver's side body wiring. The exhaust oxygen sensor wires and the left turn signal wires are about all that was needed. I ran the left turn signal wire across
the vehicle under the carpet to the passenger side where I spliced it into the branch going to the back of the vehicle. I used my pickup's original taillight wiring and added a second harness section that just serves the in-tank fuel pump and gauge sender. These enter the cab under the passenger seat through the original hole and rubber grommet and get spliced into a harness connector from the 4runner that lets it plug into a short section of harness that plugs into the main harness. The engine harness is connected as well. The only damage I found on it was a missing plug for the knock sensor. Fortunately I have a second engine harness that I got with another 22RE motor that I scored at a junk yard (it was sliced at the main trunk in the dismantling process but it's good for parts <img src="/forums/images/graemlins/kewl.gif" alt="" /> )

The rebuilt head, the lower intake mani, the e-mani, the cam, the new timing chain set, and the rockers are in place now too. So there's a little more engine work to do and the accessories, including the later style internally regulated alternator <img src="/forums/images/graemlins/kewl.gif" alt="" /> and the introduction of the new (to this vehicle) A/C comp <img src="/forums/images/graemlins/kewl.gif" alt="" />.

The thing that looks the most daunting at this point is the reconstruction of the dashboard, but I'm sure it looks worse than it actually will be. That and worrying that I'll have to trace down an EFI issue.

There are pictures that should be included here, but that will have to wait for tomorrow. -- Matt

That's great Matt!

Was the fuel tank weather coated or primed? Just curious. I'd hate to see that thing rust out on you. <img src="/forums/images/graemlins/scared.gif" alt="" />

Also, if the A/C bracket hasn't been bolted on yet, shoot some lube into the bolt holes for it and chase the holes and flush them. If the block hasn't seen an A/C bracket, the holes are usually gunked up.

I think it may have had some kind of plating, but It's hard to tell for sure. I washed the exterior with acetone two or three times and then coated it with rubberized undercoating.

The block never had an A/C compressor, but it did have CA emissions, including a belt driven air injector pump that was mounted in the same holes (most of them anyway). It never had a knock sensor though. I ran a tap in that hole and flushed it. It was a breeze. Cleaned my head bolt holes with a .410 gauge shotgun cleaning brush and solvent as well. <img src="/forums/images/graemlins/lol.gif" alt="" />

Just have to mount the AFM, air box and put the dash back together before I can start thinking about trying to crank her over. -- Matt

If I were you, I'd leave as much of the dash alone as possible and make sure stuff is secure, and take 'er for a spin. After that, finish it up. I hate dash work, that's why I mentioned it.

That's a good point. I sure don't need heaters, radios, clocks to and such to get the motor running. And I'm a little worried about the heater core pipe where it passes through the firewall. I got a little rough with it when changing the heater hose. If there is a leak and I needed to replace the pipe I'd sure be hating life if I had to pull the dash apart again to get to it.

I still have a couple of wiring mods to make regarding the 4WD switch, neutral start, and the backup lights. Most of that stuff came up through the floor at the head of the transmission tunnel in the '84 and joined the wiring harness under the dash near the radio. On the '89 (auto tranny) it's part of the engine harness (part of the plugs in the picture below) , but can be accessed near the ECU by the passenger footwell kick panel. So far I've traced down the neutral switch circuit and the back-up lights to intercept them under the dash. The neutral circuit just needs to be closed to allow the starter to spin and I am told that it can be closed full time without adverse effects. The back-up lights need a few feet of wiring and a plug salvaged from my old harness. The 4WD indicator needs to pickup a wire from the instrument cluster and connect to the ecu.

Here's a shot of tranny wires in the engine compartment that won't be needed any longer.

that happened to me when i put my engine in, i bumped the heater core and it made a very small leak where it bent. for a while i just used one of those tee's from a radiator bleed kit(available at any auto parts store) to connect the two lines until i was able to replace the heater core. of course i ignored it until the next winter b/c im lazy, but then i ended up having to change it when it was cold outside lol.

Matt that rocks... Truly an inspiration. I grew up in SE Wisco and it can be brutally cold sometimes. Got it easy out here in the West, with the ocean keeping things warm... and no rust. Good luck, don't know that I'd have the motivation to do that in the teens!

It's up and running! Started instantly! Had a slightly high and surging idle once it warmed up, but that went away after short drive. I think air in the cooling system prevented the Auxilliary Air Valve (AAC) from functioning properly.

Got it solved. It was just air in the cooling system. The Auxillar Air Valve (AAC) most likely was not getting up to operating temperature. A good run into town and back was all it took to get the air out of the cooling system and some hot coolant into the AAC. When it started functioning properly I was able to get a good idle.

So far I'm loving the 22RE/EFI swap. I can tell that it has more power than it did a few eeeks ago. I can't wait to get an SR5 instrument cluster again and I think things will get even better when I get rid of the NAPA exhaust that is behind the catalytic with its 1-3/4" pipes. <img src="/forums/images/graemlins/lol.gif" alt="" /> -- Matt
