Lexus 3.0 timing belt Toyota 3.0 3.3 bent valves interference motor

Nice video and very interesting . Right now I have a problem with my subaru forester making that sound when it starts. Thanks for the tips sir. I will change the timing belt and see if it is start back to normal.

[@joshuarivera428]

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.

[@glennfields8121]

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".

[@michaelbenardo5695]

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.

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..

@@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.

I only use AisinTB kits they are the best and come with OE parts.

[@billsmith2212]

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 .

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.

[@CubbyTech]

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

[@elevatorman427]

That waterpump sounds horrible

[@phoenixmistertwo8815]

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.

[@gmwally4537]

I'm enjoying your videos!

[@WrenchingWithKenny]

Awesome, thank you!

[@donaldlee6760]

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)

[@ferrarif174]

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)

[@marccrotty8447]

Donald. (A year later). Good point about syncing cams and crank. For right bank and cylinder #1 (next to firewall), ensure engine is at top dead center. This can be done by compression reading or physically checking cam lobes (I know, means pulling valve cover). Line up marks on Cam pulley with cutout on backing plate. With engine at TDC the left bank (front) should line up by matching the cam pulley to the backing plate cutout notch. I don't think it could be out 180° with engine at TDC and crank mark matched up. Make certain belt is facing "out" per arrows on belt.

[@garyr7027]

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.

[@johnrussell3869]

Does the lexus like old 4runner have 2 waterpumps the call it pulley bracket i think i see it in middle above the waterpump

[@M3GAN3116]

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

[@WrenchingWithKenny]

It can . Usually it will cause low compression, not zero compression

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.

[@WrenchingWithKenny]

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 !

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.

Jesus. The there are plenty of videos on setting valve timing and installing timing belt. With engine at top dead center this is an easy job. mc

[@RussellBooth1977]

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 !

[@joshroi8610]

The 1mz is a non interference.. some Toyota engines are inteference though like the 3mz. But this is not.

[@darinandalinahouse9596]

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?

[@phoenixmistertwo8815]

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.

[@Grendelbc]

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.
