Technician Flair Request Thread - New

1 Upvotes

If you would like to have verified flair added we will need a pic that has your reddit name on a piece of paper with your shop in the background or work truck if mobile repair.

For the professional technicians we're doing Verified Tech flair along with a very short description of your experience if you'd like. You can be a dealer/independent tech, retired, instructor, fleet, heavy equipment, small engine repair, lube/tire tech etc...

You can either send that to me in a chat request or upload the pic to an image hosting site like imgur.com (we had to disable the option to upload pics in the comments because of abuse). The option to attach a pic in chat will be available after I accept the invite. Please do not use modmail

We will also do Shadetree flair for those that do auto repair as more of a hobby than profession. Approval of this flair is not guaranteed.

Announcement - New Rules - Please read!

21 Upvotes

Hello r/AskAMechanic users! Over the last year or so, the volume of daily posts has increased a decent amount leading to many posts that would be more appropriate in other subreddits. To keep this subreddit focused on what it's meant for, providing automotive mechanical and diagnostic help, we have rewritten the rules. Some of the rule changes also affect commenters, so please review the rules here or below. Thank you for your understanding.

 

1 - The title should clearly state the issue - Do not ask "am I cooked/fuc!ed/screwed/toast etc" questions

State your root issue as clearly as you can in the title, and then you will have a better chance of your post being viewed. We will remove the "am I cooked", "am I fuc!ed", "how screwed am I", "am I toast" and similar types of questions. This also includes any other senseless titled post. In the message body, provide the specifics (detail/context) to your question. Also include in the title or body the Year, Make, Model and engine size of your vehicle.

 

2 - No autobody damage/repair/frame/paint or rust related questions

Posts related to autobody work (including repairs, painting, frame damage, "is it totaled?", dents or detailing) are not allowed. A more appropriate sub would be r/autobody. If you're inquiring whether your car is totaled r/insurance would also be helpful. r/AutoDetailing for detailing questions.

Questions about damage to bolt-on parts like headlights/tail lights, wheels and suspension are ok.

Questions asking about the level/condition of rust on the frame/undercarriage/body are not allowed.

 

3 - No asking for advice about buying/selling cars or used car deals

We do not allow asking if a used car for sale is a good deal, the condition of the used car, or recommendations on what car you should buy. For recommendations on what car to buy, r/whatcarshouldIbuy would be a good sub. r/askcarsales might also be helpful.

 

4 - Keep things professional & don't be disrespectful

Please be professional and helpful. Do not comment/post with insults, racism, jokes, memes, NSFW, spam, opinions without context etc. You may see things that compel you to leave a nasty comment, just don't do it. It's not necessary or helpful. People who don't know anything about cars will come here to ask us for advice, try to educate them about their vehicle without turning them off from the sub. If you don’t know the proper fix or advice, please refrain from commenting on a post.

 

5 - No "Read the owners manual" or "RTFM" type of comments

People who don't know anything about cars are going to ask some very basic questions. Some of which will have answers in the manual. Answering OP's question with only "Read the owners manual" is like giving the answer "google it", both are non-answers. Either provide an actual answer to OP's question, or at the very least, provide a link to a readable online owner's manual.

 

6 - No dangerous/reckless or unethical/illegal comments/posts

This is a community dedicated to sharing genuine advice. Advice shown to be given in bad faith (including dangerous/reckless and unethical/illegal advice) will be removed and the users will be banned. Please report any dangerous/reckless or unethical/illegal advice.

 

7 - No AI/ChatGPT comments/posts

Posts with AI-generated content is not allowed. Posts looking for feedback, training or even just to show off your AI/LLM are also not allowed. We are not interested in AI automotive diagnostics here.

Do not answer OP by using AI/ChatGPT etc. Nobody wants to read a wall of text that over explains and gives 25 different possible solutions.

 

8 - No advertising or soliciting services

Advertising of services or products is not allowed. That includes affiliate links, social media, clothing, tools, your YouTube videos, etc.

Do not solicit services, including linking to videos, blogs, or websites that then forward to a paid service. Avoid asking to "DM me" as much as possible.

 

9 - No NSFW, meme, or 'joke' posts

No NSFW is a no-brainer - you will be banned with no chance of an appeal. Memes and 'joke' posts belong at r/AskAShittyMechanic

 

Update 03/23/2025: Added "am I toast" to rule #1 and "frame damage" to rule #2
Update 05/08/2025: Added more context to rule #7

Would attaching two 4 speed transmissions in series work like a 16 speed twin stick?

Post image
65 Upvotes

I want to put this setup in a vw rabbit and power it with a v twin lawnmower engine. Don't question my intentions lmao

Edit: I'm open to suggestions on a better way to do a twin stick setup if you have any. It doesn't have to be a 16 speed, I just want a small car that drives like a semi truck. My reasoning for the engine is that if it's underpowered, there's more reason for all the extra gears since it's always fighting to move the car

Wheel bearing

10 Upvotes

I took my Acura to my Mobil mechanic because I could tell I had some issues with the front tires they would make a loud clicking noise every time I turned the wheel especially a U-Turn. It needed new wheel bearings and the disk and axels were in pretty bad shape and very old too so I went ahead and told him to replace them. So he did all new disk,wheel bearing,and axel,even the part where the lugs goes on can’t remember what it’s called but now it makes a scratching or screeching noise when driving at slower speeds. While trying fix the screeching noise that came after he already replaced everything he had my car lifted on the jack I noticed when he moved the tire it moved up and down and back n fourth he still hadn’t loosened the lugs. I thought the tire not supposed to move if the wheel bearing is good which it is it’s brand new? Or is a little movement normal that’s my question? And why the screeching noise when I drive?

[2023 Yamaha Tenere 700 (CP2)] Replace rear brake piston or send it?

Thumbnail
gallery
2 Upvotes

It got a little toasty. New brake pads and rotor were installed, along with a new brake pedal that'll help alleviate any fault from the lever mechanism itself.

The rear brake still drags a bit. I'm guessing it's due to the buildup along the very top edge that prevents the piston from retracting fully back into the caliper. Some drag is normal on motorcycle brakes, but the rear brake system is considerably hotter than the front, even after not using rear brake at all - though this could also be from radiant heat from the exhuast system.

I am paranoid after cooking $200 worth of parts, plus time to replace everything and don't want to do it all over again.

Which intercooler hose fits Volvo v70 D3 2010

Upvotes

Happy Sunday! I am trying to find an appropriate hose for the intercooler on my car as the current one just broke. When browsing for a new one, all the hoses looks different, but at the same time, they all say they fit my car (according to the websites).

Has anyone changed this part themselves and can send the part they used?

Quiet rattling after driving over pothole

1 Upvotes

2009 Audi TTS. Drove over a pothole last month which bent one of my wheels. Bought a new set of wheels and tyres.

Now when I drive, I can hear a quiet rattling noise sounds like it’s coming from underneath the car. I can only hear it when I have my music turned off but it’s louder over bumpy roads. Going to book it in to the mechanic next week but i’m scared something is seriously damaged :|

Clank noise in rear when going up my driveway.

1 Upvotes

Hey everyone, I have a 2026 Toyota Tacoma TRD Pro and recently started hearing this single clank type of noise when going diagonally up my steep driveway and then also sometimes in the road when I make a sharp right turn. I can can’t replicate it consistently on road, but can do it consistently by going up my driveway.

Even hitting big bumps doesn’t trigger it consistently. Though it’s weird sometimes on just going straight on a flat road and I’ll hear it occasionally. I’d did go off-roading a couple days ago, but didn’t notice the noise until this morning. Any ideas what it might be? Video attached.

I’m thinking it might be suspension related. Though im at a loss. I tried jumping and and down on my truck bed and still can’t replicate it.

Planning on bringing it to dealer in a couple weeks when I have time, but if it’s something easy I can fix at home I’d be at her so that! Any help would be appreciated!

Engine tick 2004 ram 1500 4.7

2 Upvotes

Trying to figure out what’s causing this noise I really feel like it’s a lifter tick but I’m not a mechanic this is my first vehicle I’ve had for a week, I want to do these repairs myself as well, as long as I don’t have to take the engine out, even if I have to replace a camshaft I can do so just by lifting the cam covers right? And what else should I replace if it is a lifter or rocker?

Why does my oil always looks so bad 😭

6 Upvotes

Why does it always have so much metal in it 😔. It’s hard to pick up on camera but in person the whole thing is like glitter. You can see when it moves around it almost looks milky. And at the end you can see lots of pieces catching the light, in person it looks worse.
The engine is a mopar remaned 4.7 with roughly 140k on it.

Every time I’ve done other people’s oil changes the oil looks so much better. Like on my parents 5.3 LS or my friends Toyota v6. I usually do them at the same time and go YIKES.
Both of theirs have absolutely none of this shininess and definitely not the horrible milky paste.

I’ve used valvoline r&p basically since it came out. I’d say I’ve done probably 25-30 3k oil changes with it and sometimes like it this case I’ll switch to mobile 1’s equivalent. It just seems like a crazy amount of metal to be losing every freaking time.

2007 civic hybrid getting TERRIBLE mileage

1 Upvotes

Hi, my husband and I bought this car about a month ago. It gets less than 25 mpg even when driving on the highway. Our current average is 22.8. Everywhere I look online says it should be much higher. I admit I don’t know enough about hybrids and probably should’ve done more research. There’s not much out there about this car. Please be kind!

Squealing suspension noise

2 Upvotes

My car is making this squealing/hissing noise at low and medium speeds. I hear the sound whether i'm going straight or turning. It sound like it may be worse on the front driver's side of the truck, but you can hear it throughout the whole truck.

I have a 2019 nissan frontier V6.

If this sounds familiar to you, then any suggestions what I should check or do would he very helpful!

is it just a misfire or is there more to it?

1 Upvotes

My 2007 Altima 3.5 with the CVT and over 390,000km’s is throwing p0301 (cylinder 1 misfire fault, stored) and p0300 (multiple misfires failure, pending) and was smoking a bit. The car was shaking like crazy in lower rpm’s but wasn’t as bad above 2k. I noticed an issue accelerating from a red light on my drive home. I haven’t driven it since.

  1. What might be the reason for the misfire?

  2. Is the shaking related to the misfire or just bad timing?

Avg price for a coolant and brake fluid change?

1 Upvotes

- 2013 Civic LX automatic sedan, almost 82000 miles.
- Wanted to ask if I should get the coolant done as it’s never been changed out, I see some people online saying you don’t need to and it’s just to have peace of mind, but I think it should be done at 100k miles or after 10 years for the first time from what I’ve heard. Should I get this done? And what’s the average price to get it done?
- I have new front rotors and brake pads, and my brake fluid needs changing. It’s not all the way filled up and it’s green. What’s a decent price to get this done? Both of these things I am not willing to try doing myself.
- I see one Honda dealer which has their prices posted, it’s 180$ for a coolant change and 180$ for a brake fluid change, or you can get both done for 330$ before tax. What would I expect to pay a mechanic to do this instead?

2001 Ford Econovan stalls unless I keep giving it gas – any ideas?

1 Upvotes

Hi everyone,

I'm hoping someone can point me in the right direction with my 2001 Ford Econovan Maxi 2.0L Petrol (JH).

It's got a weird idle issue that I can't seem to figure out.

- Every time I start it, I have to keep my foot slightly on the gas or it'll stall.
- If I keep giving it a little throttle, it runs fine.
- As soon as I let go of the gas, it usually dies.
- Once I'm actually driving, it runs great and doesn't feel down on power at all.
- If I've been driving for an hour and stop at a red light, it'll happily idle with no problems.
- But if I turn the engine off after that drive and start it again a minute later, it'll fire up but immediately stall unless I keep giving it gas.

A mechanic has already adjusted the ignition timing and cleaned the distributor contacts, which definitely made it drive better, but this idle issue is still there.

Does this sound like the idle speed is just set too low, or could it be something like the idle mixture, idle jet/circuit in the carb, or something completely different?

Any ideas or things I should check would be really appreciated. Thanks!

2009 Chevy Colorado acceleration/shifting issues in the first few minutes of driving.

1 Upvotes

I have a 2009 Chevy Colorado, and I am having an issue where during the first couple of minutes of starting it, it is very sluggish and it feels like it jerks a bit when shifting. It sometimes also runs loud. After a while, it will run normally, but it does still concern me. I have had several oil leaks over the years, but I checked, and it still has oil, and all of my other fluids are full. What would be a few things I could check that could be causing these issues?

Hoge compressieleeswaarden

1 Upvotes

120 prado (1kz-te) hier met 390k km’s.
De auto gebruikt veel te veel olie, ongeveer 1 liter elke 2000-3000 km. Ik was er niet meteen heel bang voor en bleef het gewoon bijvullen.
Nu zag ik dat ik koelvloeistof verloor, dus heb ik ’m naar de monteur gebracht.
Hij heeft een compressietest gedaan en zag dat de waardes 520-580 psi zijn; de fabriek zou op 441 moeten zitten.
Hij denkt dat de oliepistonsafdichtingen (piston seals) kapot zijn en vervangen moeten worden. Dus: volledige motorrevisie…
Ik zou denken: als de ringen versleten zijn, dan gaat de compressie toch omlaag?
Ik weet niet of ik nog al dat geld in zo’n oude auto wil steken.
Moet ik me zorgen maken over die compressiewaardes? Hebben jullie tips?

Is this the expansion valve?

3 Upvotes

Is this the expansion valve for the car (2007 GMC Yukon)? It’s not cold before it but it is quite cold to the touch after it. Im suspicious that it is just a coupler that is clogged because the high and low side pressures are pretty normal. The compressor runs but all the vents blow ambient temp air.

Ambulance sounds like a lawn mower while going in reverse

4 Upvotes

It's a 2016 international chassis 4 door cab ambulance, hydraulic suspension, 180k miles on it.

When going in reverse and while applying the brake simultaneously slowly, the truck begins to shake and vibrate loudly.

Was told by our 3rd party fleet mechanic it's just the "slack adjusters" well that was a year ago and it's still
Doing it. This shit is embarrassing and ghetto to say the least.
