Investigating an Engine Big End Knock in a Toyota 1MZ-FE V6 (EPIC Feature Length Episode)

- About two months ago, I was returning from a day trip to Brisbane (around 5 hour round trip) when, just outside of town, I heard a knocking noise coming from the engine.
I'd been here before, exactly the same thing happened around 5 years ago in my current cars predecessor, the exact same model (it was even the exact same colour, some of the panels on this car are from the other car but, that's a story for another day). Again, I was returning from a long day trip when the knocking started, only a few months after buying the car.
Now, because I'm so attached to the car (& poor financial circumstances), I can't simply junk it, I need to fix it so, in this episode, I'll be delving into the dark recesses of the bottom end of my first generation Toyota Avalon's 1MZ-FE engine to investigate the issue &, with a bit of luck, solve it...

Wow, I've got exactly the same car, same colour, right down to the paint falling off in the same places. Same tools even. Really interesting to see what's involved in this job, especially those two small bolts underneath that cover which I wouldn't have known they were there. Thanks for doing the hard yards for the rest of us. And going to the trouble of videoing it as well. You're a champion. Thanks.
That's what I do; thanks for watching...
I went to write a comment to thank the big fella for doing the hard yards first, but this one sums it up perfectly. 💪
Great Effort!
Thanks
Thanks for the experience
No problem; thanks for watching
Lucky this engine doesn't have the upper oil pan also being the main bearing ladder frame like the 1ZZ-FE.
I know, right lol. Thankfully, I haven't had to deal with anything like that... yet...
I like it ! Very practical!
Thanks Wes. Be sure to check out part two (Measuring (online now)) & part 3 (installing new bearings (coming soon))...
Pretty cool to see how it works, I have the same engine, but mine is so far not making any funny noises, so I'm glad, but good to know what it could be.
That's always good to hear. Thanks for watching
I have the same engine with bad lifter noise, I can see that the previous owner did a bad job with oil changes. I am thinking of removing the bottom and cleaning it to improve oil pressure to the top. What do you think? It is a sludged engine.
This is a case of "you're damned if you do & you're damned if you don't. Depending on how sludged it is, you could do more damage by cleaning it or it could improve the engine &, maybe, find a little lost hp; it's a complete gamble.
I have heard (& seen), the main area that will sludge is the rear head, yep, the one near the firewall under the intake. Because the engine sits at a backward tilt, if there's sludge anywhere, it'll be there.
Good luck & thanks for watching...
I got a 2000 sienna with 222k miles. The slight knock started existing after i raced it one day. Full gas acceleration 0-60
I noticed a slight crank knock 1800-2700rpm under light acceleration ,,, i went agead and noticed the other day when i pushed it to 100% it had dirty oil a year old. And pike 5k miles on oil
I think i got a worn bearing now,,, even though its still sort of otherwise reliable,,, i notice a knock every once in a while. I need to do this fix before i ruin it
A combination of old oil & high RPM will do it; as oil "wears" it gets thinner so, it doesn't do its job as well as it should, combine that with high RPM & the oil can't be circulated quick enough, creating an oil starvation issue...
As you probably heard, my issue was LACK OF oil but, the end result is the same...
Indeed, fix it before more damage is done & remember to go easy on it for around 500 miles after...
any word on those bearings? (I have the same Toyota)
I have the bearings, I haven't been able to install them due to continual rain. Sorry to keep you in suspense...
did the bearings work? I'm having the same problem
I suggest you watch this: ua-cam.com/video/4r9FoogYyPY/v-deo.html
Someone likes arpeggios \mL, my 99 Avalon sent a piston through the oil pan, so junkyard pull inbound.
Ooh, dang, that's never good; good luck with the transplant...
Not quite sure about the first part of your comment, though..?
@@PopllFixit Thanks. I have been playing guitar for 22 years, extreme metal genres, and enjoyed the technical playing in your videos. Majority of the songs had arpeggios, an extremely advanced technique.
Can you change the bearings without disassembly?

Those engines are damn near bulletproof with regular maintenance how did this happen?
If you look through the comments, you'll see I said the same thing. The three key words here are "with regular maintenance"! From memory, I think I said I neglected regular maintenance & then paid the ultimate price for my negligence...
i also thought so. i have a camry with a 1mzfe full service history i always serviced on time has 315K KM'S on the clock did the service yesterday had a look in the bottom of the drain pan and there where sparkles in it to my surprise.
Five thumbs u!!!!!!!!!!!!!!!!!!!!!!.
The music can be a bit lower, but good vid
Thanks for the feedback & thanks for watching...
Change your oil often and you won't have issues
I did point out in the video that I'm "a bit lax" when it comes to maintenance but, thanks for the (obvious) comment...
How many kms is it on?
I'm sure I mentioned that in the video but, just shy of 240k
Thats not a lot of ks for those...
No, it's not but, as I mentioned in the video, it helps to keep the oil level at least ON the dipstick...
@@PopllFixit True that will do it!I have vvti model,was running bad,i put new maf,coils,correct denso plugs,still no good,pulled vvti oil solenoids they checked out fine,soon as plugged them in run like crap,pulled wires off its running perfect now,so fknose really?!
Unfortunately, you probably now know more about VVT than I do so, I can't help you there; 2002 is the newest car I own but, if I had it my way, the newest car I would own would be 15 years older than that...
Knock knock, who's there? Rod knock
Hell that’s what’s there
