So I've been struggling with this issue for a couple months now. I was getting pretty poor fuel economy so I cleaned the throttle body and ever since it has been idling high - like 1700-1800 rpm.
...

Wow... Those are some clean pistons!!! You runnin' a water injection system or what???

Does anybody know exactly what parts come with the X01 Head Gasket Kit for the 5VZFE 3.4L V6 engine? Part # 04008-09135. 1sttoyotaparts.com has it for $87.49.

Cheers, :drink:

Awesome post Brian... Legendary!!! Thanks for documenting everything so well. I'm getting ready to dive into my own HG repair, but I have the benefit of the engine on a stand in the garage. My...

My favorite response so far... My previous opinion of Toyotas has faltered a bit due to this failed head gasket. I guess they fixed it with the MLS HG. Does anybody know when they started installing...

It will be going into our 97 Tacoma which also has close to 200,000 miles...

So, now that I got the engine with the blown head gasket out of our 4Runner (and the new one in - running great!!!), it's time to start planning the rebuild. I just called the machine shop and was...

Here's a few things I've learned in this project so far:

1) Make sure you unplug the ADD wire before you start picking the engine at all. The FSM doesn't mention this at all and I yanked the wires...

Here's a quick update...

Got the engine in, but not bolted down just yet. Just ran out of daylight.

I skipped the dowels.

I did jack up the rear axle and put the wheels on 4" blocks to tip...

I definitely like the torque rating on that 18v better, but it weighs twice as much. Plus it isn't the same voltage as your truck battery.

That snap-on looks pretty sweet. 500 ft-lb is sufficient...

Seems like a pretty cool tool to keep in your off-road rig. Now, if you could figure out how to wire up a 'dummy' battery to your cig lighter adapter or just some clamps on the battery, you'd be set!...

Thanks for the offer Jamie. I checked this morning and the wires on the other side of the connector appear to be the same colors! Sweet!

found the wiring harness for the 2002 here:

But I haven't been able to...

Thanks Marc,

With a little patience, some small tools, and a lot of luck, I got the connector apart without breaking it!

Now I just gotta figure out which wire goes where. With any luck, the...

Well guys, the saga continues... Not wanting to deviate from my standard 'MO' it's taking alot longer than I had originally hoped. I did finally get the engine out of the 4Runner and now I'm starting...

Got the engine. It's from a 2WD California truck with 82,000 miles on it. It's now mounted to an engine stand in the garage awaiting the parts swap. Will dive into that tomorrow morning!

OK Guys, I'm picking up the engine today and will be doing the swap tomorrow. Hopefully I'll be done tomorrow! I'm off work through Sunday, so I have a few days to tackle it if I get delayed or...

Thanks guys,

Here's another question. The FSM doesn't say anything about removing the A/C compressor... I'm wondering if I should remove the whole bracket from the block prior to engine removal or...

Thanks for the tips guys!

Here's a good tip I got over on Yotatech courtesy of Mt_Goat (aka Doug):

Buy a couple bolts with the same thread as the transmission mounting bolts (I believe they...

Thanks Jamie. You clarified a few things. Much appreciated!

Also, I just ordered a set of swivel sockets.

Cheers, :drink:

Howdy folks,

I'll be pulling the 3.4L V-6 out of our 3rd gen 4Runner in the next week. This will be the first engine I've pulled EVER! Our 4Runner is a 4x4 and has a manual transmission.

I have...

What a great post Jamie. Best post ever!!! Thanks for all the pics and part numbers!

I now have the confidence I need to tackle this project since the headgasket in our 96 4Runner just blew last...
