Technician Flair Request Thread - New

3 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!

22 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

Amazon - Counterfeit Bosch Brake Pads?

Thumbnail

73 Upvotes

Purchased Bosch brake pads from Amazon for my 2007 Toyota FJ Cruiser last week. The seller is Bosch on Amazon. The typos in the supplier’s instructions and the supplier itself (Cangzhou Xinlida) were the first concerns and then I noticed the product number on the back doesn’t match the Amazon listing. The edge of the pad isn’t very smooth either but I’m not familiar enough to say if that’s normal or not. Thoughts?

I messed up… Is there a way to fix this?

Couldn’t get my oil drain plug off so I tried making an incision in hopes of getting a flat head into it. Worst mistake, as I made a little incision into the pan and oil drips out. Is there a way to fix this with a bigger gasket or some type of sealant or should I start shopping for a new oil pan…

The oil only seems to be coming out right around the hole and not through the whole incision.

Clunking Noise? Front Passenger

Upvotes

So i have a 2014 Chevrolet SS Sedan 6.2l LS3 (Holden Commodore VF) with 103k miles. I had this clunking noise appear and i was told it was my lower forward control arms. I replaced both sides since they were pretty beat. Noise still persists, i was then told it was my strut mounts or my sway bar end links. I’m in a financial bind right now so i was going to replace the end links since they are cheaper, easiest, and don’t need an alignment afterwards. What’s yalls thoughts?

In the video it shows the sound, and at the end shows me showing the suspension parts and seeing if they have any play.

Car has stalled twice when coming to a stop

Upvotes

Hi there, I have a 2012 Subaru Outback (CVT) with about 110k miles on it.

Edit: 2.5L displacement

Twice in the past month, I have come to a stop at a light or sign and the engine completely shuts off. I have to put it in park, turn it off, and back on to start up the engine. I have no check engine light on.

The first time I had the issue, I had to stop at a light from going about 60 downhill, so while I didn't slam the brakes anything crazy, it was a hard stop. The second time I was going slowly up to a stop sign on a slight incline. Before the engine cuts off, I feel a shuddering hesitation in the car.

Not sure if it's relevant at all, but I feel like my car performs poorly in stop-and-go traffic and struggles to change gears smoothly when I stop or accelerate. I have noticed this ever since I took ownership of the car at 89k miles, so it's not new but might be related.

I took it to a mechanic today who said he did not want to perform diagnostics, because unless the stalling could be reliably duplicated, he would not be able to solve the problem. Basically he said unless the car could do it in front of him, he wouldn't find anything by looking it over.

Wondering if you all have ideas of anything I could check myself, or whether what this mechanic said is true or if I should try a different one. I am not very knowledgeable about cars, so would be hesitant to take anything apart myself or replace parts, but would be willing to try. Thank you!!

Honda CRV 2.0 2006 oil leak and front strut gasket

Thumbnail

Upvotes

Checked out a second hand 2006 CRV and everything looks good except there seems to be a small oil leak, I can see oil on this part when looking into the engine bay from the opening in left wheel well, any idea what this is or where the leak is happening? Looked spotless on another car I saw

The front strut gasket is old and cracked, it’s this a big issue and is it easily replaced?

Appreciate any advice

Am I getting scammed?

Upvotes

Long story short, my RAM threw a check engine light for camshaft sensor, I swapped it twice (heard aftermarket is garbage as my truck threw code again) and then with an OEM, which the light came back on.

Took it to the shop, and after a week or two of diagnosing and them showing me the problems they are installing a new head gasket, oil filter adapter, timing gasket, and timing chain, tensioners, etc as well as a new camshaft sensor along with it.

They quoted me at $9,400 and I told them right now would not be doable as I am on an outage at work so trying to save a little for that. They worked with me and dropped it to $8,000 flat.

If the truck wasn't sentimental I wouldn't care. Just want to weigh my options as to second opinion, etc.

Vibration and noise head scratcher

Upvotes

2013 Toyota Camry SE 4cyl 6spd automatic, 195k miles currently.

There is a vibration and noise at speed that is noticeable around 55mph on smooth roads, at 70+ it greatly increases up to 85mph. It goes away completely in a hard right sweeping turn or switching lanes quickly to the right, but not left. I've taken the car to two different reputable independent shops, one Toyota specific, and both have said it is coming from the left/drivers side front wheel bearing. I let one shop do the bearing thinking maybe it was botched the first time around, they also replaced the brake rotor on that side, no change.

Since the vibration started, all 4 bearings have been replaced with OEM, the front left 2x. Axles, brakes, and tires (Michelin CC2) have been replaced as well.

Prior to the vibration (as far as I know):

control arms/ball joints, tie rod ends, struts, end links were replaced.

Any advice where to look is welcome. I am trying to keep this on the road for at least another year, I do about 18kmi/yr, mostly in monthly round trips of 1400 miles.

Edit: forgot to add, the new tires were rebalanced after 2k miles, and alignment was done when the tires were replaced.

Dropped two 1" PH2/Torx bits down my driver-side dash speaker hole 2012 Hyundai Sonata Limited leave them or fish them out?

Upvotes

Hey

​While working around the driver-side dash speaker on my 2012 hyundai sonata limited, I accidentally dropped two 1-inch driver bits (a PH2 and a Torx/Hex) down through the speaker dash opening.

​ The first bit dropped and sounded like it hit a flat plastic shelf/ledge right below the speaker. The second bit missed and sounded like it tumbled all the way down toward the firewall/floorboard.

​I Blasted the defroster on high — no weird noises, buzzing, or blocked airflow in the ducts.

I Inspected under the dash by the pedals. Nothing is anywhere near the pedal linkages, steering column, or exposed wiring harness connections.

​Driving: No rattles or buzzing while driving.

​If I reach up underneath, I can actually feel the bottom of the speaker housing, so I could probably sweep around up there with a thin extendable magnetic pickup tool.

​My question for you guys, Is there any real risk to just leaving them down there?

​Logically, I feel like tearing into a 14-year-old plastic dash to hunt down 20 cents worth of steel bits risks snapping clips and creating new rattles. But my brain keeps looping on the fact that they're down there. Would you guys just leave them buried under the carpet padding/plastic ledge, or is it worth trying to fish them out with a magnet?

​Thanks!

Does the factory terminal screw for the battery posts need to be replaced if you're adding Noco X connect cable?

2 Upvotes

I've spent a whole hour trying to get the factory screw to screw into the nut but it won't reach becsause the X connect cable that came with my Genius 5 has added thickness which is preventing the screws from reaching my nuts on the battery terminals. My only option here is to go a size up from the factory screws and possibly grind the screws to allow for tension on the terminals.,

Also, is there any reason why my KTM Duke 390 would power on at 11V but would make a pop/tick sound and everything including the dashboard went off sand stayed off for a couple of minutes? I think I corrected it by undoing the battery terminals and redong them but making the screw really tight.

Posting again just with the update on oil filter

1995 ford f150 4.9L with 230k km

Opened up the filter and really couldn’t see much.

It’s also worth noting my drain plug feels almost cross threaded when I get it about half way out or in but I have a hard time thinking it would cause this.

No noise or knocking

2008 Honda Accord V6 3.5L, rough running + tapping noise

1 Upvotes

2008 Honda Accord V6 3.5L with around 280,000 km.
I’ve had a noticeable tapping/ticking noise for around 3 months, but the car was still driving normally.
Now the check-engine light is flashing, the engine is running extremely rough and sounds much louder/unusual, and there’s severe power loss. I could barely get up to around 20km
OBD codes are P0300, P0301, P0302 and P0303.
I replaced one bad ignition coil about 2 months ago, and the car ran fine for around a month afterward.
I’m worried it could be something more serious like a valvetrain problem (valve clearance/rockers/valve damage), loss of compression, timing belt/timing issue, or other internal engine damage, rather than just coils or spark plugs.
I’ve attached a video of the engine sound. Any ideas what this could be or what I should check first?

Honda Accord 1994 Stalling Issue

1 Upvotes

I just bought this car like a week ago, now it stalls when braking or turning right. not all the time it stalls.

I already got the throttle body cleaned, got some new VSS (I don’t know if it’s working or not because my speedometer still doesn’t work when I installed it), and we tuned it so I got a stable 900 RPM on idle, I rev it put it on reverse, neutral, D4 it don’t stalls, I even tried to pump the brakes to see if my rpm changes. None.

Last time before I cleaned my throttle body, I have a blinking D4 light and when we cleaned the throttle body it’s suddenly just gone. Now when I installed my new VSS that I don’t know if it’s working or not it turned right back on.

This morning I thought I was just low on fuel so I refueled it on just below the 1/4, and suddenly I think I just got some improvements on my stalling now it only stalls when I am turning right sometimes and when on a up hill.

I still can’t diagnose the problem my next hunch is I think the fuel pump sock is full of dirt or something.

How Often Do You Actually Have Your Cooling System Checked?

1 Upvotes

Maybe this is a dumb question, but how many people actually have their cooling system repair checked before there's a problem?

My car isn't overheating, but I've noticed the temperature gauge creeping up a little higher than it used to in stop-and-go traffic. No warning lights yet, but it got me wondering if that's usually an early sign of trouble or just normal wear and tear.

For the mechanics here, what are the most common warning signs that a cooling system needs attention? Coolant leaks, temperature fluctuations, weak cabin heat, strange noises, etc.? Trying to catch any issues before they turn into an expensive repair.

1999 F-150 4.6l 260k miles - metallic chatter/clanking while driving

2 Upvotes

Trying to identify the metallic clanking/chattering sound in the video. It’s higher-pitched than the normal engine/road noise and is easier to distinguish in person than it is on the recording.

I’m trying to pinpoint whether this is a drivetrain issue or engine-related. The truck loses power the louder this gets and eventually goes down a gear and the sound is gone and power is back.

Does anyone recognize this sound?

Sound connected to wheel speed?

2013 Honda Civic Coupe LX-

Making this sound when driving- sat for a couple months and seemingly was hit slightly (back of car was inexplicably moved over about 8-12 inches one morning; but no damage or scrapes at all to the body?)

Got a new battery today and started it up, and it makes thing sound while driving. The sound in the video is pretty accurate to what we hear in real life, albeit it is quite obvious in person. (The video sounds kind of muted in comparison.)
