Awesome job Mr Kelvin!!! Japan could use a few pointers from you LOL! Keep these great,Great videos coming, you are the baddest(Which means top-Dog) mechanic on the 1uz-3uz's ever,God bless you and your business!!! Craig Mac From The U.S. South Carolina.
You have to hold your head up when pointing some important stuff out. You point something's out but are not in view for us to see. I follow every step you do. You are the most knowledgeable mechanic/ specialist person I've seen on TH-cam. Keep up the good work. From Orland Park, ILLINOIS, USA. I AM STARTING TO UNDERSTAND YOUR ENGLISH. You talk fast, so I'm learning to listen faster. I also replay alot too. When I first found you, you would say "loom". Took me awhile to figure out you meant harness. Or TDC, = top dead center. Woop woop= ye ha!
This is one of my older videos, since then I have tried to talk slower but I still struggle. The footage in this one was a bit marginal but as most of my stuff is real life I can't go get another take so I roll with what I have and sometimes the info is good but the footage is poor. Im constantly trying to improve and if you watch the engine running on two cylinders you can see how fast I talk when excited. Haha. Thanks for the compliments. Im trying to download my brain which is tricky. Cheers Kelvin
Chur for the video mate! I urge people reading this comment to make sure they have the right belt. I had a sales rep try and sell me a non-VVTi 209 toothed belt instead of the VVTi 211
Great video…wish my son would have watched it before installing a new timing belt and water pump on his SC430. Unfortunately, he turned the crank with the belt on and no tensioner in place. The belt slipping and now the timing is off significantly. Any suggestions on how to deal with this? He didn’t have any significant resistance so we hoping he didn’t bend the rods.
I think one problem might be that (in the US at least) it's referred to as a timing belt, instead of what it actually is... a camshaft belt :). I see a lot of people referring to the "T" instead of the "|" marks.
Great video,, I also watched the video of the vvti rebuild. I did that but after assy it seemed the valve timing was slightly off as it would start then die, I did not do any sort of pre-load to the vvti. What would the correct way to pre-load these and direction? Thanks for any suggestions
this is a great video mr.kelvin!! lots of useful information but i wanted to ask how to set the timing correct on a 99 1uz vvti in my ls400, the previous owner tried doing the timing belt but left the timing off by a tooth. can i just bunp it back with a wrench to get it into time? thanks again!
Should the cam gears be double dot to double dot on the right and single dot to single dot on the left at TDC or can they be aligned correspondingly then the cam gear get rotated into TDC to have proper timing?
Hey kelvin, was reading over the service information on 1UZ VVTI in preparation for my cambelt change, It says to put the engine 50 degrees after TDC to avoid interference when removing the cambelt in case the cams turn from spring pressure, is this correct, I didn't see you do this in the video. Thanks.
Correct thats what the service manual says, and its not how I do them. The factory manual also suggests turning engine after cambelt is removed. I understand why I see so many people having issues with vvti and incorrect cam timing.
@@Lo-sevo The "Line" timing method confirms mechanical engine timing between the Crank and Cams are correct. The "T" is used when installing a new Timing Belt. Adjusting the Cams to the "T" position allows the Cams to rest on the "Flat" of the Cam Lobes on both cams. Therefore, there is NO Tension on the Cam Lobes and the Camshafts will tend to stay physically in the "T" position after you remove the Timing Belt. Therefore ,when you install the new Timing Belt, the Marks on the Timing Belt for the Left and Right Cam Gears will line up with the physical indentations on the Camshaft Pulleys/Gears (both Left and Right). Other wise if you don't line up the Timing Marks on the Cams on the "T", when you remove the Timing Belt the Camshaft Gears/Pulleys might tend to rotate a few degrees and you will hear Valve slap with Pistons, and trust me this will scare you. There is "Scary" metal sound that you'll hear, then you have to use a Cam wrench to line up the belt properly w/ the Cam timing marks on both Left and Right cams, makes the installation of the belt much more difficult and the Technical Competence required increases tremendously. You can make a significant Timing Belt alignment error and you wont know until you put back together all the parts and at start up of engine it will be sluggish and quite likely the Engine light will come on and a Engine Code will be set. And worst of all , you'll have to do the job over again or have it done by Auto repair shop!!
Hi, i decided to be the funny guy and check the condition of the belt by taking one of the cam gear covers off, broke a clip on the harness one side and the clip broke, fallen down. Went to start the car after putting cover back on and car wasn’t happy. It idled low and a tad rough when it fired up, but gladly enough no weird piston slapping noises or such. So considering I was going to do the timing belt anyways I’ve gone to tear it down and taken the cover off, and it’s jumped a few teeth… if I turn the cams back to the marks on the engine and crank is at TDC and put the belt on, do you think she will be okay?
Could I get the part number for the timing belt you use? I am in America and seeing as how I am using a JDm celsior 1uzfe vvti engine I cannot give them Vin number for the correct belt.
I’m working on a gs400 timing belt, I pulled the old belt and the left cam moved a good 30 degrees counter clockwise. Now my right cam and crank are perfect how can i move the left cam by itself
I am trying to figure out the firing order on my 1 UZ-FE 1999 GS 400. Also what happens when a belt breaks? Do the cam gears spin and what do i do to get it back on time? do i take the valve covers off and line up the single dots on the cam gears or the double dots? i’m confused
Firing order is the same on all uz engines, 1,8,4,3,6,5,7,2. When a cambelt breaks on vvti engines most of the time I remove the cylinder heads and repair the bent valves or replace the engine as they are often stuffed. Cheers Kelvin
Hi Kelvin On 3 Uz fe engine.I did timing belt change last year. Car runs well and no codes. I also did camshaft seal last year then still slight oil leak under the cam gears so without removing timing belt I replaced the rubber gasket inside the” do not ever open “ part of cam gear as per your other video. Other day I was inspecting the cam gear oil leak and no oil leak anymore. I did however noticed that timing belt felt loose around water pump pulley and can turn about 50 degree facing me and about 0.5 cm depression slack. It is very tight between cam pulley and crankshaft and has no slack at all. I rechecked all timing marks and it is perfect. Engine runs smooth. Is this expected ? Is timing belt getting streched?. Thank you
Bit hard to say without seeing it. Generally I rotate engine in a clockwise direction to before checking tension. A little movement is fine , but not too much as the hydraulic tensioner should keep it correct. Cheers Kelvin
@@CartuneNZ are these the ones inside the cam wheels I mean those weird round things that bolt to these metal plates that has marks on? I mean inside these things made of alloy? If they are inside of these things, then I don't have them! Any other suggestions how to read cams? I've got 1994 Non Vvti engine from SC400

I pop out the hydraulic tensioner, pop the belt forward or back a tooth and refit the tensioner. Easy as. Cheers Kelvin
Silly question...did you really just buzz off that crank bolt with nothing holding the crank on the other side??😊
Should the cam gears be double dot to double dot on the right and single dot to single dot on the left at TDC or can they be aligned correspondingly then the cam gear get rotated into TDC to have proper timing?

can you do this with the motor in the car

This video might help you find part numbers. The genuine vvti belt is 1356859095 th-cam.com/video/VRrvWHYqYUc/w-d-xo.html
I’m working on a gs400 timing belt, I pulled the old belt and the left cam moved a good 30 degrees counter clockwise. Now my right cam and crank are perfect how can i move the left cam by itself
I move the camshaft with a spanner on one of the hex areas.
Do you have a video on cleaning the vvti filter.what all needs to come off and some of the torques settings
Hello David. It's part of this video th-cam.com/video/oTScj0V0rm4/w-d-xo.html Cheers Kelvin
Great video! How much more difficult is this to do when the engine is still in the car?
Pretty straightforward doing it in the car too.
@@CartuneNZwhat about loosening the crank bolt without sir gun
@@chrisperez2503 easy, either lock up crank with ring gear or use starter motor.
