July 28, 2016 Alligator out for a walk
Check the crankshaft pulley is tight. I had a very similar rattle at idle on the same engine snd the crankshaft pulley bolt was broken.
So I’m chiming in after having watched all three videos. My dad has a 98’ auto and I have a 99’ stick. Mine is at 280k and has a clacking sound coming from the bottom end. It only makes the sound at idle when warmed up. I did some digging around and apparently it is common for the 2RZ and 3RZ to have wrist pin rattle caused by excessive play. It does not affect the longevity of the motor. It’s more of an annoyance than anything. I should note that I have done the timing chain, valve adjustment, fuel filter, coil packs, plug wires, plugs, water pump, oil pump, belts, idlers, AC compressor, and a bunch of other maintenance. The pan was off when I did the chain. My motor looked good inside. The stretched chain makes a different noise to this tick. A stretched chain slaps really loudly like the chain wants to break the timing cover. Whether you like it or not these motors have a signature sound to them. The only way to fix wrist pin knock is to replace the bottom end. I hope this helps
I’d put my money on bottom end. Connecting rods
I wish I could have been there! Amazing speech!
Yay! Great speech Gabe!! Congratulations again and best wishes 💜
Amazing speech!
Wooohooo!!! You rock!!!!
Dude I have the same noise! I bought my taco 2.4L 5spd back in 2013 w/ 176k miles. Own it for 11yrs and 200k and it still makes noise on occasion. Never could find out the problem
I still don't know the cause, but it's running just fine!
timing chain hitting inside the timing cover
My 97 Tacoma makes the same noise but only at start up
Have you ever figured out a source for your noise?
not yet
ever find what it was?
Nope. The truck is still running strong. It starts right up and gets about 25 miles per gallon here in hilly Colorado. If the engine ever fails, I’ll do a full teardown and we’ll see what was going on.
Check the throw out bearing.
Thanks for the idea! I replaced the clutch, pressure plate, flywheel, clutch fork, pilot bearing, and throw out bearing when the clutch wore out. No change to the noise. Clutch works great though!
Did you fined out what it was? My 96 sounds like this
Nope, it’s still tapping away…still runs strong!
@@gabrielaltman2401 it get louder with throttle or say your driving and let off the throttle and feather it mine rattles then the most I think it’s the timing chain and guides my oil looks clean nice and brown but sounds like it’s coming apart sum times
@@varmint223 same here.
Mine makes the same sound .
Throw out bearing
Yo tengo el mismo problema en un Toyota stout 2
Valve adjustment? Shiii, idk 😐
ever find out what was wrong with it?… only video i’ve found making the same noise as mine
No, but it’s still running strong!
@@gabrielaltman2401 let’s hope the same goes for mine, it’s been making this noise since march but still runs fine like a good ole toyota… hey if ain’t broke don’t fix it! 😅
I think the problem is the flexible plate. ua-cam.com/video/nwPhEMmDFEg/v-deo.html .
its been 3 years... u ever fix it?
I’m just about out of ideas. The truck is still running just fine, but the noise is still there. None of my attempted repairs have improved the situation.
Was that a knock?
If you're still trying to figure this out try checking the three bolts that hold the pulleys onto the harmonic balancer. I just fixed one yesterday that had the same knock.
I will check this!
@@gabrielaltman2401 no guarantee that will fix it, but the sound on mine was very similar to what yours is making. Good luck.
@@derickbowman9658 I just recently replaced my harmonic balancer, the rubber had dry rotted away. All three bolts are tight but not specifically torqued. (I don't own a torque wrench that can go below 20ft lbs reliably) The engine made the same noise with the original factor balancer as well. It's made this noise for more than 50,000 miles since I bought it three years ago. Sounds like a shaky little diesel at 1000rpm idle but goes away as soon as I increase rpm. Stethoscoping the engine with a loooong screwdriver leads me towards the bottom of the block/oil pan. Not claiming any wrong with your answer, just trying to add more information to the mystery of the infamous Tacoma tick 😭
Did you check distributer shaft ? I have same engine and so quite I cant hear it idleing.
I believe is the timing chain stretched, that sound is when the explosion is not syncronized with the valve timing
It seems that 1190khz is the main station frequency, subtract twice the IF(455khz) =910khz you get 280khz. Don't know wether this is normal on all SW-55 s.
Yes. The transmitting antenna is located about 1.7 miles from the receiver. The transmitter power is 6.8kw. KVCU Boulder Colorado radio-locator.com/info/KVCU-AM
@@gabrielaltman2401 Thanks for the info.
It is the main rod. You will not fix the noise. Just replacing the block.
The fan
it makes the noise with the fan belt removed
Its the gizmo near the blinker fluid reservoir. You just gotta give it a little more play.
Did you ever figure out what it was? I have one doing the same sound.
No. It’s still running...
Mine makes this sound as well, it drives several thousand miles a month and has been reliable to a fault.
@gabrielaltman2401 did you ever find the source? My 2.4l automatic 1997 tacoma has same noise
I have a 2001 Tacoma with the 2.4 and has always made noise after it broke-in, now has 88,000 and still makes noise but run like a top. Toyota says nothing's wrong so don't worry.
Did you figure it out? What’s the contraption you’re using? Some type of microphone probe? Is your truck super quiet other than the tick?
Oil pump
Grumpy G we’re going to find out! My replacement pump and cover just arrived!
Gabriel Altman ......take a peek at the pressure relief shuttle and spring while you're in there..
@@grumpyg9350 How did it turn out.?
Germ Medina ..... Haven't heard a word. Hope he got it fixed, and that all is okay.
Was it the pump? Mine does the same thing.
I have a similar rattling sound on my ‘03 Tacoma Single Cab w/187k miles. However, i think the issue is transmission related as it goes away whenever i press the clutch in. Any ideas as to what it could be? Appreciate any input
14nightwolves I’m not sure. Input shaft bearing in the transmission? But, that’s just a guess.
just a guess here but, check valve lash, timing chain, timing chain guides, timing chain tensioner. When you revved it up it kinda sounds like a rod bearing but the frequency doesn't seem to fit with lower end bearings. sounds like timing chain components. let me know how it turns out.
I checked the valve clearance using my feeler gauges. All the measurements were ok! I’m wondering if the timing chain is worn and is slapping against the guides. Interesting that the frequency of the rattle is low when the engine is accelerating, and high when I let off the gas. Maybe the chain is pulled tight when the engine has a load, and goes slack when decelerating?
SS Maynerd thanks, see below! Also, the noise has been happening for a few years. I figure if it were bearings, the engine would have self destructed by now.
@@gabrielaltman2401 could also be the timing chain tensioner.
@@gabrielaltman2401 how many miles and has it always been seviced on time...I suspect timing chain or tensioner
too anal, who cares
I hear the same thing in my 01 2.4 tacoma
What was the problem??
Not sure. The truck still runs, but the noise continues!
Gabriel Altman I’ve got the same sort of noise on mine. Truck runs perfect just has the ticking noise was wondering if it could be noisy fuel injectors?
Could be. The injectors do not seem to be the source of the noise on my truck. Lots of people have the “Tacoma tick.” Mine has been making noise for years.
Riding With Jacob sounds like it’s coming from the crank
