I scraped my oil pan, fixed it up and Drove for a hr. a knock started, came to find out I cracked my whole sump pan from being to low. thanks currently rebuilding and soo many threads had misleading information. Video was straight forward. appreciate the links tagged along.
Man I am doing a swap into my 94 pickup and you have NO idea how much you are helping! Great videos!
Glad I can help!!
im just starting mine, how is yours going? any tips
@@boisebiker4713 mine started and ran for a few minutes recently. but havent driven it yet. Just take your time and follow my videos. But also follow the factory service manual.
Im in the same boat. Im taking my sweet time though. I really want to do this right. His videos have been a huge help!
Very helpful. My non VVTI is the same at the bottom. I' ve just measured it has the same thin piston rings. Great to see the right part number now.
Finally! A very detailed video of the 1uz/3uz
Will help with future projects
😁😁
Great video, and love the pace of it for viewers like me to really absorb all those detailed findings of yours.
thank you!! :D
The most informative video on the 1UZ-FE VVTi engine I have run into. Thank you!! Keep it up!!! 🙏 🤜💥🤛
Thank you!!!
this is so nicely detailed. thank you so much.
Thank youuu!!
Great video! I'm doing this swap also in my 2002 is300 so looking forward to the upcoming videos
Thank you! Good luck with your swap
@@PoorManMods thanks and looking forward to your videos on getting the power steering, fuel lines and ac lines set up
@@jicez6649 haha I look forward to tackling those challenges as well
Best swap for them. Fits well and handy plumbed up
Honestly, you could've just noted the stamping on the block skirts (where the upper oil pan is mated to the block) at the rear right corner (seen in the video on the right lower corner of the skirt). Those are the main journal diameters. Also, the crankshaft is stamped for all it's journal measurements ranges from 1-5 and. They do this for discrepancies in manufacturing and they can still maintain a VERY high tolerance standard.
Yes, you're correct and that would have saved me some trouble . I believe at the time those markings were unable to be seen because of dirt or corrosion. I was looking for them and could not find them. Then when I took the engine block to the machine shop they hot tanked it and they found them.
@@PoorManMods yeah, they get caked easily. great video too bud!! I'm actually a Toyota MDT in Gulf States.
Thanks alot for this lovely vedio, keep up the great work 👍 😊
thank you!!
There are marks on the block and the crankshaft for the bearing sizes, if it is difficult to see on the bearings themselves on the 1UZ.
Adding them together gives your bearing size needed, it’s in the 1UZ engine service manual.
Got my parcel from Summit Racing just today. I was close to reuse my old piston rings because they are just inside specs. Toyota says just: discontinued. Also ordered 2 sets of 6 rings. To order one set of 6 and 2 extra is pointless because only a coupe of bucks difference. The problem with the thinner rings from 1997 on is not easy to find.
Sweet! Lots of details
Thanks brotha
Interesting. On the bearing ranks for that engine. During the machining process the crank caps are tightened to the block and a boring bar goes through and cuts all the journals together and then each hole is measured and a rank is given for each journal, so the journal and the cap should be the same. The same is done to the crank, then you use the numbers from both to determine what bearing size to use for each journal. The top and bottom are always the same size. At least that's how it is for all of the engines I have been involved with.
the top and bottoms were only the same for the center 3 bearings, not the outers, super strange lol
I am so excited
Now this content is good!
hey thanks!
Best engine swap for them. I done a 98 vvti 1uz
Great video!! Where did you find the individual Main Bearings? I can find the genuine ones anywhere.
Could you help us out?
YOUR SUPPOSE TO MEASURE END GAP WITH THE RING AT 50% TRAVEL OR IN THE MIDDLE OF THE CYLINDER NOT AT THE TOP WHICH IS A WIDER HOLE, ALL 3 RINGS MOUNTED AT 120 DEGREES APART BUT DOES NOT MATTER AS THEY TRAVEL AT THERE OWN PACE ON EACH STROKE MANUALLY LIKE A CLOCK MINUTE HAND, WHILE YOUR COMPRESSING THE RINGS AND ENTERING THE PISTON, YOU FORGOT TO PROTECT THE CRANKSHAFT SURFACE FOR ACCIDENTAL ROD CONTACT, USE WOODEN DOWELS STICKS OR SIMILAR SO THE ROD HALF MOON WONT HIT THE JOURNAL AND WILL BE GUIDED DOWNWARDS CORRECTLY
Love the toyota special mallet
😂😂
Filing on top of the open cilynders, NOICE ! Rolling on the floor laughing....
dont worry i soon realized what i was doing and cleaned the cylinders, its ok
How did u make sure u got the right thickness rod bearings didn’t see u mentioned them
Sick 🤌🔥🔥🔥
Thanks!
brilliant
Thank you!
Hey man so helpful, just bought a 3uz, just curious if the rod bearings need to be matched with the number the same as the crank bearing?
thanks! Rod bearings are not a matched set like the main bearings.
Can somebody send the repair manual link?
Pretty sure it's not recommended to clean piston ring grooves or file your rings over the engine your assembling.
lol i realized that and then moved
Putting those ring compressors back together was a fun first
Haha right?
where did you get the infor about the torque for the car ?
Is the bearing thing for all 1uz or just the vvti
They need to add a golden like button or something I can’t like it twice. Thank you for uploading
Hahaha I wish 😆 thank you!
@@PoorManMods Me too man like a once a year golden like. I watched the whole video I cannot wait for this series. I'm glad because with the 1uz there seems like so much grey area, like with those thrust bearings like wtf how did you find that! No Sir, THANK YOU!!
@Carson Loane hahahaha 😂
👌
did you feel a power difference ?
I'm doing this swap into my mx73, between you and cartunesnz I'm sure there wont be any problems
Hells yeahhh
Did it look like someone had been in there before? Could the 4/6 be made from two sets? I don’t really know, genuinely asking.
I'm 99% sure no one was in there before, it was just realllyyyyyy hard to read
What if you're planning on a turbo build with H beam Rods? Shouldn't the ring gap be bigger? How much boost can the stock crankshaft hold?
Im not sure lol
From what I've read, it's not the crank thats the limiting factor for boost. For the later 1UZ, it's the thin rods. Same for the 3UZ as well, but the 3UZ has a thinner cylinder wall. I've heard that you can run 3-5 psi in the later 1UZ and the 3UZ and not have issues. I've seen a guy run 7 psi with an eaton supercharger on the 3UZ, but it wasn't a daily.
Very nice video! I have a question for you! I have a 1uz vvti also! there I will inspect the Main and rod bearings before I start to use the engine! But need i to replace the Main and rod bearing cap bolts when I take them away or can I use the same bolts many times?
its recommended to replace the bolts because they are torque to yield bolts
@@PoorManMods alright! Where have you heard that? 😊 I found a manual as looks like it's from Toyota and they recomende to replace the bolts if the Main bearing cap bolts is smaler than 7.4mm and rod bearing cap bolts is smaler than 7mm
I have meassured mine main bearing cap bolts and only one of all the 20 is under 7.4mm 😊
@@tobiasbjorkbacka6980 It's pretty common knowledge that torque to yield bolts, especially in very crucial applications like main caps and rod caps are one-time use. I just did not want to risk it. It's not mega expensive to get new bolts and if for some reason your old ones don't torque properly..that can be mega expensive when you find out later down the road.
A good friend of mine is also a technician at Lexus, he said for warranty work that involved head bolts or main bolts, etc. They would not replace them if it was warranty work to keep the cost down, but he extremely recommended that I replace mine for the extra insurance.
@@PoorManMods Hi! Where have you bought your Main bearing cap bolts? I can not find some i can buy! Ore are some other Toyota engines also as use the same bolts?

Hey man, I noticed that you didn't hone the bore before putting new piston rings in. I know that the theory is that new rings need a new hone to seat "properly" but it looks like yours seated just fine looking at your newer videos. Have you had any oil consumption issues past the break in period on the rebuild? The reason I ask is because i'm doing the same thing currently and cannot decide if I want to hone the bores or not while I have the pistons out. Any input is appreciated! thanks!
I haven't noticed any oil consumption issues, honing it won't hurt though
@@PoorManMods awesome! That's all I need to hear lol. I'll probably just pop those rings in after gapping and send it lol. Thanks for the reply!
Can I follow this with a non vvti, obviously ordering parts that work for mine, would it be pretty similar to this?
I'd recommend following this video series as well as following the factory service manual for your specific engine
So did you end up having to buy genuine Toyota main bearing caps or were they aftermarket?
i bought main and rod bearings from Toyota, i kept the original caps
Where in the WORLD did you get the individual crank bearings that you can order based on the individual per cap size? everything I can find online only sells a full set with no different size indicator? Im completely stuck in my rebuild trying to figure out if I can run this set or I need to somehow find where I can order each individual bearing.
Shoot me an email and I'll try to help you out later when I'm off work

@@PoorManMods I appreciate the response! I sent ya an email
finallyyyyyyy
woohooo
Don't the IZs have the bearing n7mbers stamped on the block like almost every other Toyota engine?
I think they do
THE RTV OIL PAN GASKET SEALER DONT USE OR IF YOU DO MUST BE A VERY THIN SPREADED AMOUNT ON BOTH SURFACES WITH YOUR FINGER SO WHEN THE 2 PARTS MATE THE DONT SQUISH A BLOB IN THE OIL PAN, HOW MANY TIMES HAVE WE SEEN OLD RTV CLUMPS IN THE PIPE PICKUP, THIS IS AGE AND HEAT RELATED, USE A PROPER GASKET THAT WONT GO TO PIECES OR MAKE YOUR OWN WITH A MARKER AND A RAZOR/BOX CUTTER ON SQUARE GASKET CARDBOARD
I literally followed the Factory services manual...it's fine.. 😒
If the main bolts are torque to yield, aka 90 degree stretch, aren’t they supposed to be new instead of reused?
Yes I got new ones
@@PoorManMods I’m on the top end now 😂 figured as much
Which transmission are you planning to pair this with ?
W55 until it blows
is their a torque number for the oil pick up tube? pls
I just made it tight lol
What made you do uz swap and not turbo the stock 2jz
The 1uz makes the car drop about 100lb and gain about 100hp just by simply swapping it. So all aspects of the car improve
how much of these videos apply to my non vvti 1uz
probably just the bottom end, but you should certainly follow the factory service manual for your engine
why not convert to na-T? instead of uz swap?
Because
@@PoorManMods im actually curious, good deal on the uz ?
@@solidsnakec20 uz will be more reliable, lighter, closer to firewall, better torque, better gas milage, smoother engine. You can get 300hp without boost with vvti ones

haha I wish you could play forza music in this video
Yesssss
