Thanks so much bro. Ur a very nice and helpful teacher. I have my 1mz fe head gasket to change but I was scared to touch the cams so I just parked my car but now am not all that scared anymore. Thank u.
Thank you for watching and for commenting.
Very helpful in reassembling my 1mzfe. And thanks for the doc link too.
Thanks for watching.
Love your videos btw. youve done a great service to many an diy home mechanic
Thank you for watching and for commenting.
Great video , thanks a lot
Thanks for watching! Be sure to watch the companion video about the service bolt for the cam.
The dots are backwards isn't it bank 1 1 dot bank 2 2 dots and the split gear needs to be pre.tensioned.
They were installed as shown, and it works, so I don't think it's backward, and the pre-tension with the service bolt is shown in this video and also in more detail in another video.
8:59 what is this "service bolt" you speak off. When does that go in?
Fantastic video by the way. I'll be trying this in a week or so. (Oz built 2001 Avalon)
Look for the separate video on the service bolt - also in this youtube series. Absolutely essential that you get this right.
So the back set of camshaft have one dot and two dots the service manual says line up the 2dots for the rear camshaft and the 1dot for the front camshaft. Issue I’m having is that the timing mark on the back camshaft isn’t aligned with the mark on the timing cover when the two dots on the back camshaft are together.
Should I just go ahead with the manuals recommendation or try to set the time with the marks
I'm not sure what you got going on there. Follow the manual for aligning the gears with the camshafts. Then after the head is reassembled you take care of the timing marks.
I had to replace a burn exhaust valve on cylinder #4 on my wife's 1999 Lexus RX300 with this 1MZFE engine and did a novice booboo. I tilted the head over and all the shim buckets fell out and I lost the locations. Any recommendation for re-assembly? I was thinking of first placing the exhaust cam in place and use a feeler gauge and then mic the buckets.
Just thinking about this gives me a headache. You'll get through it.
So this says nothing about the other head i can only get the cams too align by doing 2 dots to 2 dots is this because the head is set tdc on the other head so its the other way around for the head at the back?
Look it up in the factory service manual.
before i remove my camshaft would be a good idea to mark em before removing so i can put them back on same way after i resurface the cylinder heads or it really doesn’t matter
The camshafts have timing marks for aligning the exhaust cam and the intake cam on each head. PLEASE LOOK AT THE FACTORY SERVICE MANAUL.
Thanks a lot for the follow up .Do you often see V6 engines with VVT rattle ?
Not so much on the 1mz/3mz. More so on the 2gr.
did I miss checking the cam lobe / valve cap clearance for each lobe of the cam shaft?
WHEN I DISASSEMBLED MINE THE REAR BANK CAMS DIDNT HAVE TWO DOTS, AND WERENT ALIGNED BUT HTE FRONT BANK CAMS WERE. WHAT DID I DO WRONG?
The marks for each bank are different. Check the factory service manual.
If i removed the camshaft with the wrong dot marks together (180 degrees from where i should have) should i install at the normal installation position or should i install the way i took them out?
This on camshaft no.3 and no.4 by the way. I took out the camshafts at the two dots instead of single dots lined up (3FE-MZ). So all the valves are decompressed now. I figured when i reinstall, i just go ahead and reinstall the way the manual says to reinstall since all the valves are decompressed now
@@charlesmaki7559 Correct just follow the manual and don't forget about the service bolt for the cam spring.
whats the service bolt use for? any bolt fits or it comes with one
Look at my separate video for the service bolt to see what it's for. Any M8x1.25 bolt will work. The bolt is removed during installation, so the engine does not come with it.
What check engine light codes were present?
Been a while, don't remember.
what is the service bolt for?
there is a spiral spring that pushes the two halves of the gear in opposition - it must be pre-loaded and the two halves are held in position by the service bolt. After the gear meshes with the opposing gear, the service bolt can be removed.

I did not see an access request from you. If you request access, I will review your request to make sure you are not a bot, and give you access. This seems to work for everyone else, I don't see why it would not work for you.
Are there any aftermarket cams for these engines?
I've heard of putting 2mz cams on 1mz.
@@Merryfrankster_ interesting, thanks! Do you think there are any performance benefits from that?
@@02SLERA Higher duration so sure.
@@Merryfrankster_ thanks
Why you dont show how you put service bolt before ?😅
What are you talking about? There is a complete video for the service bolt.
