Does anybody know the torque specifications on the exhaust manifold nuts? In the haynes manual it says 30 lbs/ft. It took an average of 45 lbs/ft to take the nuts off and 1 of them took about 60 lbs/ft.

Thank you,

I torqued the stud itself to 20 ft-lb and nuts to 30 ft-lbs. I also applied anti-sieze


Btw, do you actually work?! You have updates every day

Maybe he gets to work early and get home at 3PM?
By the time I get home these days, it's dark already. I do it all outside. Even the weekends are taken with other stuff. I have a few hours here and there now. I'm trying to marry the wiring from 95 truck to 96 engine and 98 manual ECU....

Yes I work as an EMT. We work 24 or 48 hours at a time and have a few days off in a row then start it all over again.

Thanks for the torque specs!

The baffles are different. The t100 is sandwiched between the oil pan and the block, which was a terrible design and the 4runner is bolted separate from the oil pan.

Good luck with your swap!

I think this is for 2002+ 5vz. They came with a vapor pressure sensor mounted on the tank. I either have to mount it on my tank, which is only 14 gallons or so. Or use the 18.5 gallon tank from the 4runner and hook up my generator pump from the rv to the 4runner tank.

Very small update today. I was able to scrape all the old gasket material off the 3vze oil pan and I got to say this is my least favorite thing to do so for during the entire swap.

Here it is mounted w/ new silicone:

After that I tried to drill out the tac welds holding the 4runner battery tray and was unsuccessful. I'll have to try again next time.



The motor is pretty much ready to go. I still need to clear out the engine bay a little. I also need to remove the speedo cable that comes from the tranny through the firewall to the gauges. Also need to order a new firewall protector. Anybody know the part number?

Thank you,

Navy

I found a dremel to be very useful for cutting the welds on the battery tray.

Although I wasnt trying to keep it in tact either... started with a cut off wheel to get as much clearance as I could to cut the welds.

Thanks for the tip. I might drill out the tack welds again, but its raining at the moment.

The drill size is "U", which comes out to .368". 3/8s comes out to be .375". You can go to your local hardware store and ask for a U size bit.

Good size update today.

The other day I wired wheel some rust that I saw in the engine bay. I then primed and painted it.

I went ahead a pulled a part some of the dash to get to the combometer. I unplugged the speedo cable from the back of the combometer. I found that you either had to cut the speedo cable or some how take it a part. I just used a lighter to heat up the end and the stopper came out. Now the speedo cable can fit through the hole of the firewall.

I then decided to install the tranny today.

Here they are side by side (5vz 2wd auto on top and 3vz 2wd auto on bottom):

I dragged the tranny under the truck and used ratchet straps to lift it up until I was able to get a jack under it.

The newer and older tranny mount are interchangeable. The older brace and crossmember have to be used.

Still have the urge to long travel this thing, but not sure if the 1 ton suspension is different.

Since the tire was off I thought I would see what it would look like.

The rim is not bolted it is just sitting beside it because the lug pattern is different from my 6 lug taco.

I had somewhat of a productive day today.

Was gearing up to install the torque converter. First I poured some ATF into the converter.

Then I installed it into the transmission. I had to wiggle it back and forth until it fell into place. You should not use a hammer to install these.

Also was able to torque down my crankshaft pulley to 217 ft/lbs. I used a grade 8 bolt to hold the chain in place on the stand.

I ground down the A/C bracket where it used to sandwich the motor mount.

Now it sits flush as it should.

After that the motor was ready to be dropped in.

I was working alone so I needed a way to control it as I was lowering it. So I hooked a tie down strap to one side of the engine.

Heres the motor finally sitting on the motor mounts. Only problem is the holes don't match on the driver side. Its about 1/4" off from lining up. I'm going to lift it again and see if I can get closer sometime next week I hope.

Things are moving along. Finally got the engine to sit into the motor mounts. I had to use the hoist and lift the engine and shake it a few times and lower it multiple times.

I posted that the 4runner tranny mount works on the tranny crossmember bracket, which it does, but doesn't work when then engine is in. You have to use the old one. Not sure if its because the rv is a 1 ton, but its much beefier anyways.

Had to bend some brake lines out of the way to get the down pipe in, but the frame is still in the way. Going to have to weld a jig up so I know how far to bend the down pipe. It looks like it needs to be bent 2 inches to the driver side. Hopefully lots of heat and a pry bar will do the trick.

I was thinking of buying a tube bender and learn how to do the exhaust myself or pay somebody to do it.

What do you guys think?

Also still pulling parts off the donor. Does anybody know how to unclip this? It hold the engine bay ac hose line to the ac condenser I think.

Why are you drilling out the battery tray? Just curious.

I'm using the donor's battery tray. That way I can swap the battery to the driver side. The tray is tacked in so I have to drill out the welds. I'm going to tack them in the same spots once I get it out. I wanted to use the battery tray like in your swap, but keeping this as low budget as possible.

Thanks for checking out my swap! I remember reading your swap thread and getting stoked to do mine.
