Hm... whats this sound (video link)

[axed existence]

I knew i had an exhaust leak (not sure from where exactly) already but this is a new sound. Very clicky but seems to be from the exhaust side of the engine. The link goes to a video with the engine running from both sides and some revving. The clicky sound seems to go away at higher than idle revs but it pops up every few seconds even at higher revs.

when i first heard it yesterday i thought it might be exhaust related but while listening to it today up close im not so sure.

any idea what this could be? im leaving for a 180 drive in less than 24 hours (then back another 180 miles on Sundsy)... anything i should be worried about?

YouTube - Diagnostic video
(audio aint that great, you can clearly hear the clicky noise im referring to come into play at around 0:32 when the rev drops back to idle)

Thanks in advance

I'm thinking 3 things:

1) Exhaust leak
2) You need a valve adjustment
3) Timing chain stretched /Bad tensioner


I think you'll be ok for the trip, but it's not gonna get any better. Good luck.

I'd check the valves, about 30-45 minutes if you know how to turn a ratchet.... And you're slow! The valves would sound louder on the exhaust side cause that's the way the air is moving through the engine.... Very sewing machine sounding..... Check the valves!!!!!!! Do it!

Hey! Mine kinda sounds like that!

Seriously, these guys have it all right. Your valves need adjusting. And your Timing chain is stretched/loose. I would make replacing the chain a priority pretty quickly.

You should be fine for your drive, but if/when that T-chain breaks--then you'll be pulling the head and replacing a couple of valves instead of just adjusting them (and that's if you're lucky). It cost me $1600 at a shop to have that failure repaired in 1999. I have no idea what it would cost today.

i see... well thanks for the headsup guys. im gonna go ahead and take the risk... it will make the trip that much more exciting. actually i kinda have no choice. i was planning on taking the car into the shop day after i returned anyways so this kinda is convenient in a very optimistic kinda way.

heres to a safe trip eh?

by the way, in case anyone was wondering. im heading to joshua tree national park (california) for a weekend camping trip.

listen to the other vids that come up with yours.

this one has the timing chain, broken timeing chain guides sound.

YouTube - toyota 4runner 22RE

I would guess that the two little gaskets where your manifold meet exhaust are shot.
did it built up to that sound or start all of a sudden?

 

[ToyotaNick]

and when your driving is there a ticking that increases as the rpm's increase?

it seems its been building up... the fluttery air noise is easily heard when stopped but the semi high pitched squeeking is brand new. is say its been building up because it had some trouble passing CA smog this year. i discovered it had the exhaust leak after having it looked at (plus, i could smell it when stopped). he didnt repair it but managed to temporarily do something so that it passed a 2nd time.

i watched that video. my engine definitely does not have that grinding sound after the revs drop.

and when your driving is there a ticking that increases as the rpm's increase?

the ticking of the valves does increase. im not sure if this is how the engine sounds or if they need adjusting but i'll have that checked. the clicky metalic noise that is heard at idle doesnt seem to increase as the revs increase. it could be that its just not audible over the engine as its getting louder but sometimes ill hear some clicks at the higher revs if i go there slowly and pay attention.

but i just got back from the trip (about 400 miles overall), no problems with the car. thanks for all your suggestions i ended up taking it fairly easy as a result. i suppose ill post up what it ends up being when i find out.

Turns out it was in fact the timing chain guides. The chain itself did not need to be replaced.

I love how the 2 failures of the 22RE engine have happened to me within 6 months of ownership (chain guides giving up and exhaust pipe cracking). Is there anything else that might be catagorized under "the 22RE is a great engine, except for..." that i should keep in mind, rather ''wait'' for?

 

[Nikon Samurai]

I was just going to say, sounds like your chain guides broke and chain is eating your water pump housing, which is exactly what happened to my engine

FIX IT BEFORE IT KILLS YOUR ENGINE :G

NS

 

[axed existence]

oh its been fixed. did the repair after another 100 miles after the trip (grand total ~500 miles on broken guides). I just realized (months later) that i never posted what the actual issue was.

@Samurai: Im curious... how long did you ride on broken guides before your water pump housing gave out ?

I ask as i mentioned to my mechanic how long I had driven that way and he assured me that 500miles was nothing to be worried about. I know that now as he didn't find any issues once he was in there replacing the guides and seals and tensioner, if i remember correctly.

I drove it for 3 months after I got it, the sound got progressively worse.. the PO had driven it for a couple months before that I think with them breaking down.

If you could get a look at your timing chain cover, this is what mine looks like after I've done a little repair:

Either way with the guides being bad I'd think of it as a ticking time bomb

That's only b/c either you or the PO won't listen.


It'll be the thing in your glove box that is in pristine condition,

I'd read the owners manual if I was going to dive a vehicle...

This is not how you drive Toyota's. This IS how you kill them or start to doubt their quality.

You do not fix as you go, and, only fix what appears to be damaged....

You now have a ticking time bomb of a timing chain unless I didn't read where it was replaced...But that's ok, you have the money to do head work and a timing chain replacement when it breaks.

And if it's got any miles on it, I'd rebuild it if it was that tore down.


Ask 2ndGen to show you his pics. And his chain was prolly newer than yours.

Take it from an idiot, read the owners manual and when it says "at blah miles, replace blah" do it. Don't wait for it to break and it never will.

 

[WristPin]

I am obviously too late.

a jacked guide will always make this sound.

your idle is way too high, and it sounds like you need to fix an exhaust leak.

 

[WristPin]

Hilux, the guides, chain and the sort are all serviceable, maintainence items.


Ax'd E, there is not a way to complete your sentence 22REs are good but..."

these engines are strong, durable and last as long as 500,000 with out needing an overhaul. As long as scheduled maintainence is preformed.

 

[axed existence]

the repair was done by a toyota and lexus certified technician who has been doing what hes been doing for the past 15 years. i trust him when he says the chain is good.

the engine has 109k on it. previous owner was also a toyota technician and currently manages the service drive of a different dealership.

@hilux. i understand what youre saying about scheduled maintenance and general preventative maintenance. that would have avoided broken guides had i performed the service but i dont see how the exhaust crack could have been prevented. the pipe is properly connected and secure.

To re clarify, since this thread is gaining activity again, the repair has been done. thanks again for the tips.

 

[Hilux]

Yeah, to people that know what book to read. The rest blame it on Toyota


Sorry it's just a sore subject to me, and why we have less and less trucks to chose from. They're going fast to SA. People that know a quality rig are buying it from someone that could not read and perform the maintenance on it. They just let it die and bought another because "it's old it'll start breaking down all the time"

You need to ask your tech if he would replace a good pilot shaft or TO bearing if he was doing a clutch job for you...




Listening to a "Tech" = job security

Dunno why the chit-chatters give you so much s*** all the time, but I gotta say you're a badass

I thought I was a dying breed...

My timing chain issue was a fluke.... The metal backed guide broke, and it went between the chain and sprocket and snapped the chain. I doubt it's happened more than a dozen times in the history of metal backed guides...
