Black soot and rattling noise (Videos and images attached)
 

I've attached some youtube links to shorts that I've uploaded.
The first link provides the sound I'm hearing. This sound does sometimes go away when the clutch is pressed in. I believe it to be a TOB but I could be wrong. However, it kicks on when the A/C is turned on (shown in video) This confuses me as to how the clutch sometimes effects the issue.

Below are two links to the soot I'm referring to. It looks like it could be oil based off the location and the drip spot shown in video.

I plan on taking it in to Toyota soon to have them look at it. I want them to check if it's running rich, inspect the engine block, catalytic converter for damage and a squeak from the engine bay. When I was parked at a drive through the squeak was so god damn loud lol.
If anyone has any information/theories/advice that would be super appreciated.

How does the serpentine belt look? Worn belt could squeal, and it makes sense that the AC engaging making it worse. If the belt is slowly disintegrating it could be throwing rubber dust around, making it look sooty. Also check all pulleys while you're at it to make sure none are seized/hard to spin, especially the idlers and tensioner.

Edit: now that I actually listened to the video it's not belt squeal. Sounds like engine load dependent, so turning on the AC would make it worse. How are your engine mounts?

I can't get over that air filter setup. You went from a factory cold air intake with a panel filter to some aftermarket intake that is picking up hot air from the engine bay. You filter is also not oiled.

That is oil residue. Either timing cover or OCV leak or spill from filling.

That’s assuming that I did this, but I just bought the vehicle. I took the cold air shielding out so I could clean it and have better visibility. The car is being driven as minimally as possible until I can diagnose the issue. The previous owner put the mishimoto cold air system on, not me.

As for an oil leak, that’s what I’m worried about. How would I go about finding the possible leak?

I have encountered a few people mentioning engine mounts, but I haven’t been able to check them yet. I’ll check the belt later. Something was squealing super loud at a drive through last night, I assumed it was the belt or TOB, leaning towards belt. Unfortunately, the squealing was not occurring when I record the video

You've been driving it minimally at least since late February. Is that rattle an exhaust leak, or is it your transmission? Does the rattle quit when you disengage the clutch?

Writing about it won't help. Gotta get in there and fix shit.

it could've just been a spill from overfilling.

first step here is to clean the motor and see if the problem re-appears.

as for the rattle, check the exhaust connections and hangers. if the exhaust was replaced at any point, or swapped back to stock before you got it, it could be any of those loose connections.

I can't figure ownership history from a picture, just calling out what I see. I recommend getting some K&N filter oil as those pleated cotton filters need to be oiled to do their job. I personally don't care for K&N's.

It's a common oil leak on these engines. You need to pull the engine skid off and degrease the front of the engine to even figure out where it is coming from. That skid plate is supposed to be brushed aluminum and yours is black so it's been leaking for a very long time. If it is just an OCV, easy fix. If it is the timing cover, then you need to determine how bad the leak is and decide if it is worth bothering to fix. Timing cover reseal is an engine out affair and is easy to screw up. You may be able to get away with cleaning very thoroughly and smearing some RTV where it is leaking.

As for your noise, i'd want to address that pretty soon. Sounds TOB'ish to me. Neglecting that for too long means replacing the front cover of the transmission too.

Welcome to a new episode of Just Rolled In - customer states they tried fixing an oil leak themselves but it still leaks :lol:

I have been driving it normally, only the past week have I been able to look really into the problem. I cannot tell where the rattle comes from, it sounds like it could be an exhaust component but I believe it to be the TOB. It does sometimes goes away when the clutch is disengaged. Though it’s not consistent. I’m gonna schedule an appointment soon, I’m trying to finish up schooling so I haven’t had the time to deal with it but I will here very soon. I’m posting here to get information/leads as to what it could be and learn more about the vehicle from knowledgeable people.

I would like to mention that the rattle seems to appear when the engine has warmed up. It comes and goes. If Im driving with the AC off it can appear but more often than not it’ll rattle when the AC is switched ones (shown in video)

I’ll look into the OCV as that seems plausible for causing the gunk. I wiped my finger on it earlier, Today, and it was super thick. I hope it’s nothing huge such as the cover.
The TOB has been a concern and what’s mainly been alerting me. I’m writing all of this down to bring to a Toyota shop to see what they say. Thank you 🙏

It’s got a corsa exhaust system installed. I’ve wanted to check the connections but haven’t been able to jack the car up to get underneath it yet.

Believe me, I died a little inside typing that :D If it's the actual timing cover that is an expensive repair. As a DIY'er it's not an easy repair either so I don't want to recommended someone take it on not knowing someone's skill level. There have been a few people who have bandied it and it's been okay. So I don't feel too bad about saying it.

Seems that time spent taking and posting videos is more valuable than actually working on the problem.

I’m sorry? Not every one can expend hours digging into a car on a whim. I’m loaded with work. My free time does not allow for me to work on it. Excuse me for at least inquiring on a forum about my vehicle. As I have stated, I have an appointment soon, I’m here to only get information and opinions. Making such videos only takes a minute or two and the information given by other forum members has been pretty valuable and informative. I don’t know why you would even post that.

I post this because you've been at this for months. It takes fifteen minutes to jack up the car and actually look. Half hour tops.

It's not just you. I call it like I see it. If you have time to read and reply to all these posts, you have time to roll underneath the car and look for yourself. Excuses are like, well, you know.

I’ve made two posts. Two. If you have a problem with that, then just ignore the thread. You’ve added nothing. I’m obviously new, I’m here for information not a lecture. It may take you “15 minutes” to jack up a car. You do not know my schedule or financial situation. I haven’t been at this for “months.” I made one post about my transmission. My transmission is still fine, for now. As for the “if I have time to reply then I have time to work on my car” (1) I’m reply via my phone. You have no idea what I’m doing outside of that. So no, even if I’m replying doesn’t mean I have the time to work on my car. (2) It’s stupid to compare the time required to post something to working on a vehicle.
My vehicle is of no concern to you as to when it gets done. So if I decide to wait that’s my decision. I was simply asking for information not a lecture.
You had an opportunity to fulfil what I assume is this forums goal to help with issues and you failed that here, and to the comment about how it "seems that time spent taking and posting videos is more valuable than actually working on the problem." am I not working on it by learning about what it could be from knowledgeable individuals?

This is supposed to be a car community/forum. “I call it like I see it” man, that’s just something rude people say.

It's threads. You started two threads. Now you're spending time arguing with me when you could be setting up the jack stands.


Oh, hey. I just remembered another thing that leaves behind a lot of soot, exhaust manifold leaks.

No dude, you’re just an ass. Who gives a shit if I make a thread? That’s what the forum is for. Two “threads” in three months has your panties in a twist.
You’re assuming that I can even work on my vehicle right now. I replied to your first reply where you asked me about the exhaust etc, and i added more information and what do you do about it? You say that shit. I got home at 12am last night and made those videos before calling it a day. Do you really think I’m gonna work on my car, in the dark, not knowing what the hell im looking for at 12am? So why does me making a thread, asking fair questions, and replying to people who are trying to help me bother you? While I made a “thread” in Feb about my TOB simply just asking a god damn question, this post was about the soot/possible oil. I only added the TOB to the post because I got a clear audio recording of the event in question. I’m here for information, not to argue with you but you involved yourself in a thread. In the future, when I post, feel free to ignore them.

I appreciate you trying to help by mentioning the manifold leaks. I do. I’m sorry if any of it came off wrong, but I’m going to be asking questions and that’s fair. I’ll get to my car when I can and in the meantime, I’m going to learn what I can about it.

Now let's not get hung up on panties. You wanted it to be about the TOB back then and months later, you still don't know. Meanwhile, you kept driving it. If it was your TOB, it would have left you stranded a month ago.

If you had gotten underneath it back then, it's possible that you might have caught a crack in the exhaust manifold before it may have burned the seal on your timing cover which could have caused the oil leak. We'll never know.

Shouldn't you be studying for finals?

There you go, actually providing something of value. I didn't want it to be about the TOB asking a question is not "wanting" it to be the TOB. I honestly have no idea why you care so much about that post. You're so hung up on what I'm doing it's baffling. Answer or don't answer the question, no need to be critical when it's not your property. I haven't had the time to drop my god damn transmission. If I did, I would've done that. I seriously don't understand what's hard about that to understand. Stop worrying about what I have and haven't done. If I hadn't made that previous post you wouldn't be complaining. This is a forum thread for issues and you're acting like I have spammed the forums.

This is going nowhere. I appreciate all who have provided information, even you maroon. I'm still open to conversation pertaining to the related issue, but I'm done with this particular discussion.

so many panties

when things go sideways on the holder-of-the-mcmaster, things really go sideways...

"jus remember folks! sittin' on yer ass won't finish yer project!"

mmm

Ok, one last review for clarity.

1. In February, you started a thread about the sound you heard. Yes, you wanted it to be the TOB.

2. I mentioned the possibility of an exhaust leak and recommended getting underneath to check.

3. If it indeed had turned out to be an exhaust leak, there would be no reason to "drop the goddamn transmission." Mystery would've been solved right then in fifteen minutes.

I don't give two shits about your car and what you do. Your post history is a perfect example of someone who prefers writing about their issue rather than actually doing something about it. You blew off my recommendation back then and it's quite possible that your inaction bit you in the ass. For your sake, let's hope I'm wrong.

Once again, put down the cell phone and pick up a wrench. Anything else is bullshit.

He may not own a wrench. Yet.

Hey, we all gotta start somewhere. I remember my first wrench.

Edit: And if you don't wanna wrench, then just take it to a reputable shop and throw money at the problem until its fixed.

Well this went off the rails lol. Didn't see the other thread.

Ah, but then OP shouldn't have implied that he has a wrench. Garbage in - garbage out. I kind of suspected that but I still take him at his word no matter how defensive. ;)

Makes more sense now, right? Edit.... ok, he started out about the fuel gauge but that recording, yikes!

OP, post a photo of your toolbox!

lolol :clap:

I can't believe anyone would buy a car that sounds this bad idling. Gezuz.

Yeah, I was like WTF is Ultra acting like this dude beat him at a game of Dejarik. Then I looked at his post history.

Fixed.

Inside Joke.

Just a subtle Star Trek > Star Wars dig ;)

And well played.

Again why do y'all care about the other thread? I mentioned the fuel gauge because I wanted to see if there have been issues with it. The dealer lied about how much they filled the tank, I almost got stranded on the way home because of that. There have been no issues since, I only wanted to ask to see if it had been possible that they lied. I had no idea that making two threads about something would irk people. As for the TOB, that noise didn't start for a few days after the purchase was made. I was quoted at an $800 for a trans pull, money I do not have at the moment. The gunk was never noticed, but it has been there since the vehicle was purchased upon looking back at older videos. I reposted the video to this thread for further clarification on what that sound was since it was a much better video. It's obvious that I am new, I have most of the tooling required for the job. Your whole thing is basically "I told you so"

I barely even mentioned the TOB in the previous thread, that's why I wanted to ask once again. Especially since I noticed it can be effected by the AC being on or off. The sound still more often than not goes away when the clutch is disengaged. I am inexperienced and that confused me. I felt it would be okay to ask forum members, since forum members are usually passionate and helpful people. Am I wrong for that?
"my post history is the perfect example.." there is barely a post history established. It was a very quick thread in Feb, you gave information and I thanked you for that. I was appreciative. That's all there was.
I was not home when replying, so I couldn't "grab a wrench" again it's stupid to assume someone can work on a fucking vehicle just because they're replying to replies for information. It takes only a few minutes tops to reply. I'm here to learn. That way when I go in knowing more about what I'm looking for and what to check for. I figured that would've been obvious since that's the forum topic. I'm not "writing" about my issues, I'm asking questions. Something I'd assume most people do when looking for something they don't know. I did not "blow off" your recommendation. I thanked you for that and circumstances stopped me from being able to have the free time to do so. I still plan on doing it.

TLDR: Feb thread was about the fuel gauge. Since that dealer nearly left me stranded. I only noticed the rattle a few days after the purchase. The sound only appears when the engine is warm. maybe I didn't notice it and it was there, who knows? I was excited. I planned on working on the TOB ASAP, as I had the time. I no longer have that time due to unexpected circumstances. I don't care any further if you decide they're excuses. I posted once again for clarification and added on with questioning what that gunk is. I am inexperienced, why be so hard because of that? I am taking steps to work on it by learning more in the meantime. I feel that to be responsible. I will have time do work on it here soon or take it into a shop. If I hadn't made a thread in Feb no one would be saying anything.

I think you guys need to hug it out.

Ahhh. I don't know much about the whole Trekkie world so it went over my head. It helps that I am really short.
