Lexus 3.0 timing belt Toyota 3.0 3.3 bent valves interference motor
The 3.3 is an interference motor and the 3.0 is non-interference.. My 2000 avalon has the 3.0, I changed the belt as maintenance a year ago and it's been good.
Yeah these people have no clue what they are talking about.
According to Toyota/Lexus, the 2000 3.0 V6 is a "Non Interference" engine. Same goes for your Toyota Sienna. If only all manufacturers that used timing belts instead of chains would have been nice enough to at least make their engines "Non Interference".
If only motorists were smart enough to refuse to buy cars with a rubber timing chain and the water pump inside the timing cover, automakers would quit using them and would return the water pump to OUTSIDE the timing cover.
1mzfe is a non interference engine the 3mz-fe engine is a interference engine
Very lucky customer
Great videos Big Kenny...keep wrenching...
Nice to find a mechanic who understands about timing belts and interference motors. A couple years ago when decent used cars were impossible to find at a reasonable price, I found a 2000 Chrysler 300m with only 105k miles in beautiful shape, dirt cheap. It was bought new and well maintained by a little old lady (really) who was just too old to drive anymore. i wanted something considerably newer but pickings were slim. Manual said to change timing belt and water pump at 100k. My mechanic (he's the one who found me the car) really didn't want to replace them. Said if it ain't broke don't fix it. Finally convinced him to do the work. I switched to synthetic oil, changed trans filter and fluid. It runs like a dream and I'm thinking I'm just going to keep it because it might last another 100k. I've only put about 3500 miles on it since I bought it.
Hilarious joke… the 1MZ is a non inteference engine and any “mechanic” or anyone with access to google should know that. 🤦♂️🤡
THE 3.0 LITTER ENGINE IS NONE INTERFERENCE, BUT THE 3.3 LITTER ENGINE IS THE INTERFERENCE ONE. THAT'S WHY THIS ENGINE DID NOT BENT VALVES
Might want to do some more homework on the 1MZ-FE engine. The reason the valves were fine is that it is NOT an interference engine.
the vvti 1mzfe are interference

I have sort of a love-hate relationship with timing belts. I had an 83 escort and being too cheap to put on a new water pump the first time I replaced the belt I had to do it a few months later because the water pump went. It was a pain but I got where I could do it pretty quick after a while. Keep the good stuff coming Kenny.
Good honest guy. Good job Kenny
I'm enjoying your videos!
Awesome, thank you!
Good job man, what a finding!
I guess it's easier to put the belt on than manually closing each set of valves and doing a leak down test . You probably would pull the plugs and look in each cylinder and use the bore scope to see the valves closed . Either way the front cover is off to turn the cam .
Melted Timing Belt ..? Yikes they got lucky 1) your their mechanic 2) just happened to have the right timing belt laying around 3) didn’t loose a very good motor… tragedy narrowly avoided..
Im actually amazed that the valves didnt make contact !!
@@WrenchingWithKennyI’m amazed you don’t know anything about cars.
The 1MZ is a NONinterference engine… meaning it CANT make contact with the valves no matter what. So no. Not possible.
Never seen a timing belt that severally torn up. Most definitely the water pump did that, the bearing is completely shot and noisy as heck. You'd think the owner could have heard that bearing from a block away. Crazy loud.
I only use AisinTB kits they are the best and come with OE parts.
timing belts on an interference engine is the stupidest thing to me
Yea , but good maintenance jobs !
@@WrenchingWithKenny If! the customers do the maintenance... I've seen many a car DIE before its day because the customer killed it by NOT doing REQUIRED maintenance...or they selll the car when they see how much it's going to cost to do the job and let the new owner worry about it....
This is a non interference engine… 🤦♂️
Thumbs up for the carnage! Kind of amazing that no damage was done on an 'interference' engine. Still a mystery on what could have caused that catastrophic failure - I'm guessing the water pump seized and friction did the rest. Cheers Kenny
The 3.0L v6 is a non interference engine.
@@BullyCanadianlmao these people have no clue what they’re talking about. The 3mz is an interference engine… the 1mz IS NOT. 😂
I have the 1MZ-FE engine, and the belt was barely hanging onto a few teeth that it had left on a belt well over its mileage. I caught the issue as the VVT system was clanking enough for me to check out the belt, and I happen to catch it right on time before it slipped. Thing is, after buying the kit and timing it all with all the marks including the ones that were on the belt to aid in timing, I get no compression on 3 cylinders that are accessible on the radiator side. My question is, can the VVT system, if out of whack, even beyond those alignment marks on that gearing, could that give me little to no compression. I hear the range of the VVT is about 40 degrees... If that is true, then perhaps that side of the motor has a busted VVT, hence the clanking, but it shows me that the marks are indeed, in timing with the cam gear. I do know that looks can be deceiving, certainly someone has had this issue before, with a busted VVT system that wont allow the car to be in timing.
I refuse to buy an engine that uses a rubber timing chain, and I refuse to buy an engine that has the water pump inside the timing gear cover. That's why I still drive a 73 GMC and a 54 Chrysler HEMI. No catalytic converters to steal, no computers to force me to bring them to a shop, no smog checks, lots of room, and in the Chrysler, a nice soft ride.
Very curious as to why the belt appears broken parallel and not perpendicular
That waterpump sounds horrible
I'm curious how you synced the crank bolt with the camshafts after the belt breaks. As you know there are 2 rotations on the crank for 1 rotation of the cam, so there is a 50% chance that when all the timing marks are aligned you may be off by 180 degrees, or can either rotation of the crank work? (I suspect it's the latter)
no matter, just put the crank on the mark , and the cam on their mark.. (make sure to to look for the dot on the outer part of the crank sprocket not the inner)
I have a question I need a answer for asap and I think your the man that can answer it for me.
Couple weeks ago my Highlander with 3.3L interference engines timing belt let go. I’ve secured a used belt to do the exact same thing you did in this video. Maybe I’ll get lucky too.
Since my crank pulley/ balancer takes 2 full revolutions to get the cam pulley back to TDC how do I know where to set my crankshaft? How do I know if in 360° off or not when installing the belt?
Line up the crank TDC mark, to the mark on the engine, and line the cams, to the mark on their backing plate, and you will be set. If you happen to purchase the Mitsuboshi belt, it has marks on the belt that help this along with timing, but you still have to physically match the marks for each pulley like normal, and then use belt marks to ensure you arent a few teeth out.
Gee, I just throw timing old belts away. Oh no, another reason to not throw junk away, ha ha.
It was ironic that I had just replaced my Sienna's belt the day before lol
All the 3.0 are non interference vvt or not only the 3.3 are
I thought all the 3.0 are non interference except for the VVT
@@norbertoespinoza5158 yeah I thought the same, defered me from buying this rx but in fact the vvti are non interference too
Nice I was literally about to do the timing belt on my Lexus IS300 but now I'll just wait till it snaps. Lmao 🤣
@@norbertoespinoza5158 oh damn yeah u have a 2jz not a 1mz either but your non interference still
What a minute why did Kenny say that it was an interference engine ?
Does the lexus like old 4runner have 2 waterpumps the call it pulley bracket i think i see it in middle above the waterpump
Yes, you're lucky if it's a Toyota engine & the timing belt snaps because they're an interference engine but you're not so lucky of it's a Nissan or a Subaru engine which is.
My brother bought a 2000.model Subaru Forester which had valve work done to the EJ20J engine because the old owner couldn't afford the expensive timing belt replacement for that engine since the kit alone costs $1000 AUD on average & that's before the labour is charged on the belt replacement.
It turned out much more expensive in the long run !
The 1mz is a non interference.. some Toyota engines are inteference though like the 3mz. But this is not.
Thankfully it is a Toyota non interface engine .
If was an other Asian , European with broken timing belt inference it be going to the junk yard.
A Toyota even with broken timing belt they still just won't die.
Would a slipped belt cause no compression ? My 91 Honda Civic turned off while driving cranks no start seems to be getting fuel air spark. Don't believe timing belt broke. Haven't done compression check yet
It can . Usually it will cause low compression, not zero compression
@@WrenchingWithKenny thanks 👍
I saw blood, that's an extra ten bucks on the bill. 😉
I have an 08 Acura TL , I was at a stop light when my car turned off , boss said it’s definitely the timing belt, it’s an interference engine aswell
What are the changes my valves are okay? Car turned off at a stop light , wasn’t moving.
It is an interference motor , but I've had about a 60% success rate with interference motors not being damaged . There really is no way to tell until you do the belt. I will say this though, when you go to line up the marks , pay attention to when you rotate the crank and the cams so you don't contact the valves upon assembly. You may have to rotate the crank slightly or the cams slightly to get timing where it needs to be . Let me know how you make out !
@@WrenchingWithKennyyou have no clue what you’re talking about bud, 1mz in non interference.
I need help with 05 chevy 1500 brake booster plz
Whats the issue ?
The front brakes lock up after I replaced everything in the truck
this is a freewheeling motor like most toyotas without vvt.1mz--fe
gas motor toyota diesels are rare i the usa
V 6 to. 50000 miles runs like know
If it is not broke, why fix it, until the timing belt snaps and grenades the engine? Always considered timing belt engines to be "disposable"? Somebody prove me wrong?
That’s not possible. It’s a non interference engine. Cant make contact whatsoever. Cant “grenade” from snapping a timing belt 🤦♂️
No this is not an interference motor go back to technical college you didnt pass
Noninterference engine.
