Gotta put the video on pause while I go change my oil ....

Like kids with a new set of lego, hands everywhere 😂

This strangely looked like med students disecting their first cadaver

hands coming in from every direction to disassemble a small motor. how many redbulls did you all have. even the talk was at 2x speed :P

You know what this means? Time for a no budget big power build. Get two hybrid 2AZ-FXE intake cams re-timed to performance lobe centerlines to make a cheapo race cam motor, some cheap forged rods and pistons, maybe epoxy the deck if you're feeling spicy, then Rav4 to the moon.

How appropriate that this was for the oils campaign

4:03 not a cam sensor, it’s a vvti solenoid, if it’s full of sludge then there is no oil to the vvti controller then the cam leaves the chat 😂😂

Absolutely not a waste, love seeing things like this! I watch I Do Cars engine teardowns, and just seeing them is always a cool thing. The fact you've got your buddies with you and you're all putting in your input and stuff was super cool to see! I'd love to get somewhere to disassemble and rebuild an engine some day. Cheers for sharing with us Marty (and bois). :D

Yeah how long ago was this Rav4 project because the Brumby is in the background?

i reckon most of that engine is salvageable. the crank is probably fine, you can check the rods for roundness and size. the head would be ok, just need a new intake camshaft. it might be a good block to keep around if you plan on keeping the rav just in case the new wrecker engine grenades itself too.

That sludge...yikes. wouldn't be surprised the oil change made it worse, unlocking the sludge and blocking the oil passages.

That piston movement within the bore isnt an issue, its just the piston moving within the piston ring clearances.

All the lads working like a well oiled machine.

5:04 IN THE BIN

The best teardown vid I've seen for ages. Cheers 🙂 🍺

Cheers fellas, keeping me entertained whilst my flight out of Paris is delayed.

5:05 you would expect some1 with so much bin throwing experience to make that..

My Mini has been in storage for 7 months... BRB, going to do an oil change real quick.

Love the Brumby in the background!! :D

Rattlin' like a diesel

I wanna see you guys spice these engines up a little more man. Cams, stroker cranks, rods, big bore, cams etc... I wanna live vicariously thru you guys. Yeah nuggets are fun.. but let's see some absolute beast nuggets every now and then.

2:52 I love how he’s taking his time, numbering the buckets, so they all go back in the same place afterwards…

nothing like a good tear down! was waiting for this.

For what its worth - The hole in the upper shell of the bearing typically leads to a very small hole in the upper half of the rod, which squirts a small jet of oil towards the piston/cylinder wall.

I love forensics, this was great, thanks Marty and team

After the "Dyno Disaster" i was patiently waiting for this lol. Not the bearing I thought shat the bed but jeez that's sludgy

Man, that was awesome. That late night garage vibe is what we want to see. Do more of that raw, unedited stuff. Looking forward to. Cheers!

Best disassembly video I've seen in a long time. Salutations

Good work team. Appreciate the detail

Excellent video, I have been watching, worth recommending

This is why I love mcm even behind the scenes no egos, no bullshit, just a bunch of dudes who love cars and messing with them

Super interesting, ty!

I have torn apart a couple of Lada 2101-2107 engines, most of them look even worse than this one, because back in the day they had no good oil, so ran M10 oil. But the engine is so simple and designed with large gaps for bad oil to flow, so it works like this for pretty much the whole life of the car. Oh and nowadays we don't have thick oils, so pour 15-w40 and the engine is not happy. It likes 15w-50 and still has low oil pressure. They fixed the issue on their newer engines like the 2108,2109 and the Niva.

Regular maintenance is key. Also caring about the vehicle you drive, it’s amazing how many people buy a car and do nothing to it but out fuel in it, drive 100k to major failure. No oil changes, pretty much nothing, then mad that it didn’t go 1 million miles

I wish I had this many friends into tinkering, a night wrenching with tons of friends who know their way around tools sounds like an insane good time !

Its really a joy to watch smart people doing something that interests them. Spinning spanners with mates is one thing, but great brains there too.

Brumby in the background, thought it was auctioned off ages ago

Isaac, what a legend. Love how he's always in a rush when he speaks!

This vlog was alot of fun watching all the guys work together. Looked like they were having fun. Were kababs provided?

The Brumby is back for warranty issues...!! Ha ha.. Love your work guys... Now i know why you guys are in shorts...!

This is so good watching the boys go through it all. Just what super garage was designed for! I spy the brumby build

That doesn’t need to go in the bin. It’s rebuildable.

This is a good excuse to build it and then Send It Marty lol

Check out another channel on youtube called "I Do Cars"... it's a guy in Missouri USA who owns a salvage yard (wreckers to you guys) and his whole thing is tearing down blown up engines to see why they failed. Some of the failures are catastrophic others are like the RAV's engine... it's a pretty interesting look into why and how engines blow up. He also does videos on how the salvage business works. In most cases, the engine failures are caused by neglect... lack of oil changes.

Good job Marty Friends Fixing the Engine Well done👏👏👏👏👏👏

It's amazing that engine was running just fine up until the dyno.

A disrespected nose engine breakdown...nice! 😎

Marty "Its a Bin Job" Me: "We Want a Built 2AZ!!!"

My Dads old work truck 4.3 chevy V6 didn't get many oil changes. I assume it looks like that. Had a few leaks but it was self sealing and self rust proofing. It still ran mostly fine, got it up to 430k miles and I was supposed to get my license but didn't and we got a new truck. So the old one got parked and the frame got rotted some then it wasn't fit to drive anymore. That motor looks rebuildable. Parts cleaner, like one of the big steam ones. Then flush out your oil passages I'd imagine. Probably worth doing since its a toss up as to if you're going to get one from a wrecker thats been maintained well.

Marty I have to say you have a stellar group of friends!👍

I imagine that's how Mighty Forensic Dissections looks like when they get an interesting case. All the mates gather round and start poking around and throwing parts IN THE BIN.

Look up BG dynamic engine restoration. It will clean out all sludge and galleries. Worth doing on any second hand engine you fit to ensure that oil flow can be as good as the pump can drive it. Of course excessive wear caused by previous blockages will still exist but pressure and flow can be as good as the existing components can allow.

The UK is done for engine tuning now. New cars to be fitted with speed limit governing software, So handling is all we have left. Wont be long before all cars have a box telling your story on board.

Thats so funny more and more people turning up to investigate as the video goes on.

Service your cars people, even if it’s a Camry.

When I get a "new to me" used car, I like to change the oil over and over until it comes out clean. Some cars only takes 2 or 3 changes. Some cars take 7 or 8 or more. You don't have to drive that far either. 50 to 100 miles is plenty of time for the new oil to soak up as much sludge and crap as it can hold before you drain it out and replace it. When I did this on my old matrix I finally got the engine so clean after 7 or 8 changes and 100 miles on each, that when I checked the final oil I put in it I could hardly tell it was on the stick it was so clean, I seriously thought I had no oil for a minute haha. I highly recommend this though. I don't think many people know that you can totally clean a sludged engine just by changing the oil back to back until it comes out clean.

Got to love Isaac.... I'm going to go and change the strings on my guitar and lower the bridge

Would love to see Issac on the channel more (or his own if he has one). He seems to know his ass from his elbow in this kind of stuff!

These are very interesting. always wonder what causes failures, so identifying that is great!

Ill be doing this sometime in the next few months. Retiring my Lancer/daily either when i get a replacement car or once rego runs out. Car has 441,000kms and the motor is starting to make some unwanted noises (timing chain sounds), and oil hand some sparkles in it on the last oil change. So ill be pulling the motor to see what condition its in. Can say, heavy traffic has not been friendly to it in last few years.

The Brumby giveaway car really shows the time lag between filming this video and waiting until the release of the Supercheap Auto commercial. A classic example of hurry up and wait

yeah wow, that is up there. i pulled a motor that sat for 10 years and prior had no love and it looked like this.

Ah nice 👍🏽 waiting for the X-ray video 👍🏽👍🏽

i have a G13bb engine from my 2000 jimny that this was going to happen to, i caught it before and now i am going over everything in there

Interesting tear down, a classic example of neglect! Most of this bearing damage would have occurred before you guys got your hands on it - the extra bearing load would've been the last nail in the coffin. Though, the piston rock is normal. It's a cold engine and everything that moves needs clearance. Even a piston with as little as .001 clearance will rock a surprising amount. This 'rock' is exaggerated from the piston skirts being barrel shaped. This very normal and necessary movement is often misconstrued with a worn piston or cylinder. That hole in the rod isn't oil supply to the bearing - that's the cylinder wall squirter, which will be aimed at the thrust side of the piston skirt & cylinder wall (normally to the left looking from the front). The feed to the rod rather comes from the main journals, into the crank pin and out into the rod bearing. The oil hole that's blocked with bearing material didn't cause the bearing failure, but rather the bearing failure has simply blocked the cylinder wall squirter.

Well you were right about the top end noise. These engines are kind of known for sludge if you try to do 10-15k mile oil change intervals with synthetic. I did 5k changes with regular oil and never had anything more than a gold colour under the valve cover.

Oil and engine flush with BG kit. Every year. Got almost 400k 3.0 TDI and still strong

Tip of you're unsure of an engines history is to run liquid moly oils cleaner with cheap oil a few times through the engine. You can tell from the drained oil how dirty the engine is and if it needs several flushes it can mean a manual inspection and clean plus some repairs may be needed.

I think Marty had a sneaking suspicion when he swapped covers. He seemed more nervous than usual on the dyno.

I've purchased a few used cars over the years, and I always baby the vehicle until after I do an oil change with a shot of Seafoam in the crank case, and then a second oil change to get the previous owner's sludge out. After that, the oil stays pretty clean and the vehicle runs well. I don't understand why you would try to get more power out of this motor when you haven't done anything to check the state of the motor, or even do a flush of the oiling system. At the very least, you should have done an oil change.

I work at a pizza shop as a driver, the Rav GTR 34 would make an awesome delivery car!

Balance shaft delete is pretty common. I did it with all my 4G63 motors. Was rougher for sure but I wasn't looking for comfort.

That's why I pride myself to make sure my car serviced every time it needs it.

Maintenance schedulle are only the big lines. The manufacturer is unable to predict if you are going to do only very short trips, or how you are going to drive your car. I've always followed the maintenance schedule, to realize it wasnt enough for my use. Now when i check the oil level, i also check how the oil look like, And 4 times more oil replacement than what was asked for ( it's cheap and easy to do, not that much a problem). Just to say, sometimes it's not just bad care about an engine, it can be also manufacturer recommendations, that in some uses, are not enough. Check often you oil, and any fluid in your car. Not only the levels, but also how they look and smell. If you start to care cause you ear an odd sound, the engine have already suffered. Well, i've learned that the rough way, so i was willing to share my 2 cent

I'm guessing that the car is for the SuperCheap Auto 2024 oil commercial, so the message is on point. 😉

Oh what a feeling

I've had the balance shaft phenolic gear let go on my 2AZ, after a cracked radiator caused overheating and I tried limping it back home..$2000 later my JDM replacement is a rattler upon startup but after 20 seconds it is perfect. Never gonna be a power house but reliability is my goal. It hits redline without issue and doesn't burn oil so I'm sorta satisfied. Regular oil changes are key. i changed oil pans and valve cover so i had a chance to inspect the internal. No sludge for me. I'm curious about making real power tho, so carry on.

I like that Mech. Stig is showing his face on the channel more lately!

@6:30 that is the counter balance shaft assembly, the phenolic gear (not plastic)will break apart and stop up the oil pickup tube...

Very informative, Marty Bush Science Guy

It amazes me that we still are making engines more and more complicated. Maybe UX/UI designers should take over the business.

I rebuilt a 2az-fe for a Scion Tc was not cheap even going with some chinese parts the ticket is put the gen1 intake cam in it and the gen3 rav4 exhaust cam it has some chop and really wakes one up

Run diesel oil in an unknown engine. It has MUCH stronger cleaning agents in it and can help clean out old sludge. Change after a week. BTW, diesel oil can also free up and old/marginal manual transmission. Same process. Only run for a few days, then put gear oil back in.

Nice teardown video. Now I just need the rebuild video, so I can get my Rav4 back on the road xD Nah, just kidding. Hope you guys will fix this engine though. Love watching videos when people tear down these everyday car engines to find the problem, and then rebuild them :D

meeting of the minds!!!

I'm happy that I change my oil regulary, far within spec 😆 the spec says 30k km for my VW Passat TDi, but I change it at around 20k km, which means I change oil twice a year 😬

The V6 also fits the rav4. Would be cool to build up one of those.

exact thing that happened to my engine. Toyota 1zz. Openly admit to poor maintenance. Mine happened at 185k miles. Car leaked and burned more then I could ever change. So it was just a matter of time before low oil level and heat caught up with it.

IN THE BIN! sorry I got excited

Love an episode with Issac

Aah $50 won't cover. It's more likely $100 and a $30 filter. Still sound advice. I love you guys.

so clean the block and a few new parts and it will be fine still work I dont think it should go to the bin.

Sell the bottom end… somebody wants a block & crank cheap 😂

made me go change the oil in my xr6t =D

One of the first things i did when i got my project car was change the oil.

"No windows in the block" lol 🤭

Marty cant you guys do a video with the dirty sludge wreckers engine? Like what stuff you can do (if any) to get it clean without opening it up? Change oil every 500km, add petroleum/kerosine, use additives etc.

IN THE BIN!

Also add a oil flush

Freshen up💫💥💯🔥
