Toyota 3.4 Liter 5VZ-FE Engine Replacement

[19963.4lsr5]

Seriously. That one bolt is a nightmare. A long ratcheting flex head wrench helped though.

Also getting the motor mount bolts/nut back on was a PITA. Why couldn't they use studs instead of a bolt and nut??

Yep and when my 96 got T boned on that drivers side mount there wasn’t much room to get that rear bolt out.

I left that bolt out of the inspection cover. My trans has 282,000 miles in it I doubt it has another 100 in it. So it’ll be coming out eventually.

Where does one buy a new replacement engine and what is the approx. cost?

Watch the video, Tim recommends Yota1 and gives a bunch of very good reasons why. Not sure how much they charge, and it's highly dependent on the importer/seller, but If I recall when I checked ages ago the average was in the $1500-2000 ballpark.

I have around 2000 into my rebuilt engine.

Thank you Tim and Sean!

Check the video description for a link to Yota1 Performance. That's where Rey got his rebuild engine from.

Having done this job before (twice), I can appreciate the fact that you guys are making a video for it as more and more of these trucks will need heart transplants in the near future.

What was wrong with Ray's engine that he needed to replace it?

Well done guys!

Rey's engine spit out a spark plug out of one of the heads a while back. He repaired it with a helicoil insert but lost faith in the engine's dependability. He likes to go hunting and wanted confidence in his rigs ability to get him in and out of the backwoods he hunts in. So, he decided to buy the rebuilt engine from Yota1 Performance.

I’ll be interested to see how you handled the torque converter bolts. To me that was one of the most pain in the arses.

Getting the top inspection cover bolt out with anything bigger than child’s hands......

We show how to separate the auto trans from the engine in our Auto Trans Replacement series. Start watching at 17:03 in the video below. I found a flex head ratcheting box end wrench works well to get the inspection plates bolts off. The one furthest on the driver side I attack by facing my body towards the front of the vehicle and getting the ratcheting box end wrench on the bolt. If you try to go from underneath, there's no where for you get get your hands or wrench in there.

The flex plate bolts are easy. You have someone work a ratchet and 19mm socket on the crank bolt turning the engine clockwise while you're watching the flex plate rotate around. You get a bolt at around the 7 o'clock position and then you can get a socket or wrench on it. The person helping you holds the crankshaft firm every time you're breaking free and removing one of the 6 bolts. Then you tell your buddy to start turning it again until you get the next bolt in position to break free and remove. If you watch the video, you'll see first hand how nicely this system works provided you have a friend to help you.

Watched it last night. Very thorough as we have come to expect. I really appreciate the 360o view of the new engine, especially the rear.
Useful as another reference for when I get around to doing the fiddly valve cover gaskets.

Thank you for posting this video!

I'm starting my engine swap today. I was thinking about removing the front end of the truck to pull the engine and transmission as one unit, but after watching your video, I'm going to remove the transmission from the engine instead. I replaced the clutch myself about 20 years ago and I remember a couple bolts being a pain in the ass, but it's still less work than removing my ARB bumper, radiator, grill, and all the other components up there. I'm just crossing my fingers that the JDM engine I bought isn't a piece of shit.

Really enjoying these. Making the thought of doing my valve covers in the spring feel much less daunting. Now if I just had a garage to work in...

is there performance in yota 1

I am pulling the trigger soon on a replacement motor for my 98. For the Yota 1 I have read a lot about in on their website and as much as I could online but the one thing I haven't figured out is if it is a direct replacement or are their any modifications/performance enhancements to it? I am going to install the supercharger on it while I have it out of the car . Does the Yota 1 motor have more hp or torque than oem motor?

Great videos I've watched all 3 so far, going to watch again for notes soon!

This is a very good question. I'm pretty sure this is an engine rebuilt to stock specs but I'll call Nick who owns Yota1 Performance and let him know about your question and maybe he can make this more clear on his website. I'll get back to you on this soon.

I did talk to Nick at Yota1 Performance and his rebuilds are to OEM specs. There are no performance enhancements.

Yep, as you could see in the video, I was pretty damn happy. My dancing was a dance of relief after laboring on that job for 4 very full and tiring days.

excellent resource!

Tim,
I've watched all your videos over the years and have a great deal of respect for you and your partners who have put so much time and energy into providing videos and pictures to help the Toyota community in general. I think I have some idea of how much time this takes! A big thank you.

As our 4Runners age, its inevitable that more of us will have to travel down the road of an engine replacement. I indeed made this journey in 14'. I thought I might share a link to my job, a view of a layman getting it done...:

My Engine Swap in progress!

I definitely ran into a few snags but saw my way through. It's now been 6 yrs and 70k kms, and she's still humming. Totally worth it. If I ever have to do this again, I could probably do it in a third of the time.

Thanks again for all your efforts, for providing an invaluable resource!
