It makes me so mad when the last person to service the car has tightened the plug to elleventybillion lbs......and they haven't used a washer....
I used a washer and I dint overtight my drain plug but it still dripps 😫 even got a new washer and plug still dripps I'm going crazy
I can't stand it neither the last person who had my car before I bought it from them has done same damn thing I was trying to change the oil and now I got this problem because of a idiot who didn't know what they was doing in the first place when they should've just left it leave alone
@@veronicawatson2525 dealing with the same issue
Glad to know that it actually takes a lot of overtightening to strip the threads. First time I did my own oil change.
Not really. Perhaps in that example but your mileage may vary. Just snug it up, check for leaks (with engine running) and check it again the next day.. Tighten a little more if needed when engine has cooled down. Cause more tighter ain't more better. Kudos for doing your own oil changes. I just did the 40th one on my 2006 Toyota Matrix.
Your best investment for your dyi garage is a torque wrench. If the manual states 37 NM of torque, for example, you torque that. No more, no less.
And 37 NM is not allot of torque, I was impressed that my torque wrench clicked that fast the first time I used it, so over tightning those screws is really easy
Thank you for this video. I was trying to google “what happens when you strip a drain plug”. I understand what it means when the plug is stripped, but I didn’t understand why or how it strips. This video is perfect because of the visual representation thank you

Good visual of what not to do. Some knucklehead at a shop overtightened mine on my Genesis Coupe, and it ended up costing me $365 for THEIR error. Small claims court was out of the question (small claims court is a joke). Never again, I'm back to changing my own oil after a 15 year hiatus.....
+Vegan For The Animals Ⓥ Thanks for the feedback!
@@1AAuto thank you sir !
Apparently satan tightened mine
I'm gonna do my first oil change and it's the same here😭
I retired from Boeing with over 35 years as an aircraft maintainer.
Please do not be misled; installing a bolt with the proper torque is important for various reasons:
• If you over torque you risk damaging the threads; either immediately or over a prolonged period of repeated over torquing.
• If you under torque you risk that the bolt will loosen over time, with vibration and/or expansion and compression of applied pressures.
• These failures can be expensive, and time consuming especially when the item with the receiving threaded hole hard to replace, or difficult to get to.
You will often hear seasoned automotive mechanics brag about how they have the feel for the proper torque without a torque wrench. However, I guarantee you that if the bolt could be tested; they would not be within tolerance. I have heard plenty of horror stories about people struggling to remove over tightened bolts. Many times these bolts are mistaken for cross threaded bolts. More than likely the threads were galled due to over torquing. The mechanic, who says he’s been doing it for ages, has more than likely never been the one to have to remove his hacked up work.
Continual gradual over-torquing can cause the threads to deform to the point that they become galled at some point in the future, or just fail to hold.
Cheap DIY torque wrenches are OK, but have a sloppy tolerance as to their true torque value. Generally, good manuals give you a torque range. Ex: 28.9 - 32.5 lb-ft. Use the midpoint value (31 lb-ft optimum) to help compensate for the tolerance of the torque wrench.
Torque specs are very important to the longevity, and proper functionality of items being joined. It is why Boeing pays good money to inspectors who are supposed to assure that the maintainer uses the proper torque.
Torque specs are not just dependant on the material type, material length, diameter, and thread size of a bolt. Torque specs are also reliant on the same criteria for the material that the bolt is to be mounted to, including the depth. In addition, torque specs are also dependent on the material that is going to be sandwiched between the two.
Ex: The oil drain plug for a 2009 Hyundai Elantra 2.0L DOHC is a M14-1.5, and has a torque spec of 28.9 - 32.5 lb-ft (31 lb-ft optimum).
The oil drain plug for a 2011 Ford E350 super Duty XL, 5.4L is also a M14-1.5, but only has a torque spec of 17 lb-ft.
The biggest visible difference being that the latter comes with a rubber “O” ring gasket; while the Elantra has a soft metal crush gasket.
Now, if I were to have tighten the E350’s drain plug to the standards that some knuckle draggers suggest; I would have shortened the useful life of that “O” ring, and possibly even damaged the bolt, or threads on the oil pan (depending on the materials they might be made from).
Personally, I got tired of the inconsistencies in advice from different people and sites, so I signed up for a long term access to maintenance data for both of my vehicles, at ALLDATA DIY.COM. While not as in-depth and user friendly as professional service manuals I used to have for previous vehicles; ALLDATA is still accurate, and a lot better than the grape vine. Professional manuals used to cost me anywhere from $120.00 to $250.00. Chump change compared to the savings of doing maintenance myself.
I wanna know how to remove that loose thread plug. Pls tell me how
1:20 Jiffy-Lube recommends using 1/2 air-impact driver for best thread striping action.
Jiffy lube dont train their techs not to over tighten.
its because they have a thing called a "lube audit" where essentially someone comes and torque checks the drain plug randomly and instead of the techs torquing the bolts they just tighten the shit outta them with a wrench because a torque wrench wont tell you if something is overtorqued
I had an issue with Jiffy Lube. They paid to replace the oil pan. They couldn't deny it was them that overtightened the drain plug since I had service records showing that they were the only ones who ever changed the oil on the car
Everyone should pay particular attention to what he said about not to use too long of a wrench. Don’t ask how I know… If you use a longer wrench you can over tighten without realizing it since you use less force to achieve same torque.
+A B Thanks for the tip!
This is exactly why I’m having to watch this video ☹️
I saw ruined oil pans quite often when I worked at Valvoline. most common drainplugs to be over tightened were on Hondas. I had to install quite a bit of pan savers. I've also seen a few overtightened 12 x 1.25 plugs, and the boss would put an oversized M14 x 1.5 plug in which puts tons of metal shavings into the oil pan, and there's no guarantee that half assed job of rethreading is going to last. Now I'm working for an oil change and tire shop for a dealership where they got workers doing things right.
valvoline uses impacts on the damn things 😅
Is there a way to remove stuck oil drain washer from the oil pan itself or should I buy a new oil pan?
Awesome
G'day champ, so could you say got until finger tight and then half turn? I've done it a thoudand time on my old cars but now I have a new car and freaking out lol about something so simple.
I go finger tight. Snug with socket wrench. Then muscle it about 1/8th turn. You feel the threads engaging and the resistance ramps up, that's all it takes. Wipe the area down with a rag and move on. Give it a peak after filling and running the car for a minute to check for leaks. If yours has a lock washer, best to replace it. I think most modern cars use a flat rubber gasket now that's reusable.
I used a tortorque wrench on my 2018 Tacoma, spec is 30ftlbs. Question is if I used a Chinese wrench and set it to 40 instead of 30ftlbs, what's the odds of it being damaged? I removed and looked to see but oil all over threads. The bolt looked fine and the threads where still there but long term damage is what I'm concerned about.
the problem with cheap torque wrench is unreliable, which means the real torque could be higher or lower than indicated. Get a good torque wrench and take care of it, gonna be good for life.
An over tight oil filter is worse than a drain plug. At least one I can understand.
what was the approximate torque right before it stopped getting tighter and eventually spinning freely?
Tnx
+Sainu Sainu Thanks for checking us out!
im not clear on proper tightening & did not show us visually. So hand tighten than a quarter turn??
I'm having this issue right now
my dealer didnt tighten mine and it fell out
Now how do I get it out?
Update* I replaced the pan. 😭😭😭
You buy a new car
Is it true that the torque spec is only 10 ft. pounds on a Ford F250 drain plug but is 30 ft. pounds on a Toyota RAV4? !
Hey this happened to me yay
JB weld the hole. No problem
Looks like that drain plug may be screwed
Express oil always uses impact wrenches 🤦♂️
Thanks for showing us what not to do, but not how to fix it. SMH
Hey, I brought my car to an oil change place today. The guy comes up and shows me my oil pan plug and tells me that the previous oil change place messed up. The plug has metal from the insert stuck to the plug. He told me that he solved the problem temporarily by getting a new plug and screwing it in and snugging it up so that it was tight. I should be concerned, right? 😂 😢
got a car off marketplace and its like they drilled this bolt in
Sooo Advice on how to fix this problem if Valvoline... Yeah Im calling them out...does this? I just need to know how to get the bolt out safely I have a fix coming.
+AScruffyGinger All you need to do is use a hand wrench to loosen it off. It's more important to not crank on that drain plug.
@@1AAuto Ive tried using a box wrench and it just spins in place. It spins both ways it wont loosen or tighten.
@@1AAuto Btw thank you for taking the time to answer my question.
+AScruffyGinger Thanks for watching! If you are having issues like we show in the video then you will have to replace the pan itself.
i used about 30nm to tighten my x1 2016
plug, is that too much?
If the manual says 30nm than no.
My Land Cruiser asks for 37nm, so i torque exactly that
how to fix
I did this and got so mad I couldn’t get it out and punched the fridge and sprained my hand
it's painful to watch
I don’t know why they Tighten it up hardly 🤷🏻♂️
It almost looks like it's designed to do that! Which isn't a horrible idea incase someone who didn't know better tightened it as much as the guy in the video did lol. Of course they would need a new oil pan but that's probably one of the easier repairs to be done
Oil pan is a $1000 repair.
Easier repairs? On aome vehicles maybe, but very expensive.
Dirk Turrell not if you have to take the engine out like on most rwd vehicles
Good idea to use a torque wrench do this will never happen
I didn’t see your ranch how much you tight it! You didn’t view your socket!
Good thing oil pans are cheap
But cost of labor to replace, or a tow job and maybe a rental car in the meantime is not cheap.
Yea but the cost for labor sucks. I was quoted $185 and thats with bring your own parts. So I have to buy oil pan, plug, oil, filter and gasket. Am I missing anything? All that together is easily a $500 job just for a damn plug.
Install one in a 4wd and let me know how cheap
Scary
