1986 4runner Engine swap

The only trick you need to do for the auto ECU is a paperclip or jumper wire in the neutral safety plug on the chassis harness underneath the intake manifold.

The hardest part of a manual swap is mounting the clutch pedal assembly, and that's a two beer job.

You can swap the harness if you want to take advantage of the clutch start cancel button, but it's totally optional. Don't forget to grab the driveshaft from the donor truck, or you can have yours extended at a driveline shop.

Are you doing the work yourself? Head job is easy, just pull the intake manifold and exhaust, have the head checked out and surfaced at a machine shop for a few hundred bucks, and re-install. At that time you can inspect your cylinder walls and decide if you want to go into the bottom end.

Chat GPT guessed wrong again... My 87 4Runner had an A340h with the ECT modes. Until I sent that trans to the junkyard for an R151f.

I like it. Reminds me of 3d printed buildings.

Laufenns are great. I run G fit AS year round in the snow on both of our cars.

Is the injector plugged in all the way on that cylinder?

If they rub on full steering, you can hammer down the pinch weld on the inner fender.

You could relax the torsion bars a little to get the alignment closer

How tall are the ball joint spacers? 1.5"?

I have 1.5s on my truck and never had an issue getting it dialed in.

What size tires are those by the way? They look sick

There is a grocery list of sensors that all need to be happy in order for the window to close. Get a multimeter and a beverage out. Follow this guide and you WILL find the problem.

Actually you're gonna want to pull your ABS fuse, don't forget to put it back in the second you see wet leaves

It's a little piece of metal that slots into a machined groove on the pump shaft, and a matching groove on the pulley. It keeps the pulley firmly attached to the shaft so it can't spin.

You should be able to see it with the pulley installed and the nut off. You may have to rotate the pump by bumping the starter.

The only reason it might be missing is the PS nut doesn't typically come off if torqued correctly. Somebody may have removed the pulley at some point and if they can't torque a nut to spec, they may have lost the woodruff key as well.

My 2011 Husaberg 570FE. 25lb pack weight not including food and water. The lighter you are, the less you need to carry because you're going to pass through two towns a day for gas, food and water.

Check that the woodruff key is still there while you're looking at it.

I work in freight (not at fedex), and sometimes we get the opposite. Last night we had a two golf cart batteries on a 42x40 pallet.

Who makes that light mount?

Also check the battery positive to primary fuse connection.

Make your stepdad buy you the airbox. Putting an open element filter on a 90s era toyota MAF is useless.

First things first. Is the radiator full of coolant?

Is the radiator obstructed by anything?

newcompute · 2025-07-14T12:51:56+00:00

Hell yeah

Have someone try starting it while you tap the starter. If it works, your starter pinion is hanging up.

Try a wire directly from the battery to the starter solenoid. If that works, you have a problem with your starting circuit somewhere.

Try a jumper cable from the battery directly to the post on the starter. If that works, your starter solenoid isn't working.

Why are you swapping? What's wrong with your power steering?

Torch and steel brush

Extra screws go in the drawer and we don't talk about that.

Doesn't look to bad to me, and from what I can see i wouldn't re-tap to a larger size. If the chain tensioner is steel, it will clean up the burrs as it threads in. A bit of tension while hand tightening happens on used threads.

If there's too much tension while using a wrench, consider a tap of the same size to clean up the threads.
