Can't get oil pan drain bolt off

Those sizes are far more common to euro vehicles, Japanese have used 10, 12, 14 compared to the euro's 10, 13, 15.

 

Does Fumoto still have a 1/8” diameter hole for oil to drain? Still takes 20-30 minutes to drain the oil pan?

 

Its fine, I torqued with wrench and no more dealership free service left anyway, so i wont have hard time getting it off next time. I almost broke the plastic housing, like last time after dealership tightened it so much that i couldn't get it off and needed pneumatic.


Its nice outside so I think i will do AC drain mod now, i have the materials already

 

Is this good? its touching some cables, but not touching manifold

 

Euro vehicles? I guess. Mostly for my mustang and GM truck.

 

I've found that one set of metric tools with damn near take care of all of the needs for both my Yota and my BMW - keep the evens with the truck, and the odds with the car!

 

Best set i ever bought was a small crescent brand kit, it tucks out of the way nicely behind the seat. Having run a performance shop and several years as the mechanic for an endurance racing corvette I have more tools than I'll ever likely use again.

 

Yep. Throw a zip tie on it if you're worried or just in case it shifts. I forget where I loosely tied mine to.

Glad you're off the dealership service and doing your own work!

 

I would take it back to the dealership to have it fixed. If it strips you want that to happen in their hands. Have them put it in lightly. Then put in a drain valve and never worry about it again.

 

To add to what others have already said, there’s a damned good chance your torque wrench also is no longer well calibrated, or (more likely) that it cannot accurately measure torque as light as 30 ft. lbs. Most 1/2 inch torque wrenches, e.g., are not accurate for torque specs under 60 ft. lbs. or so. If you are using a torque wrench rated for >200 ft lbs., do yourself a favor and buy a smaller one for the lighter jobs.

Also, if your oil pan was just a few degrees warmer when the dealership last installed your drain plug, it would be very understandable why it would take more than 30 ft. lbs. to remove the plug.

 

I actually cut off the drain and made it short, to the side. I couldn't bare thought of heat doing something to it

Yea I just was using dealership since it was free and it included other stuff like tire rotation, grease fittings etc. I can't do tire rotation at home , or at least haven't tried yet

 

It is possible I guess, i have only used this torque wrench 2 times only

I used regular husky wrench to untighten, took me some pull but finally did. I was just not putting strength to it fearing it would break, but its fine now. I tightened it to correct specs so won't have issue taking it off next time.

 

From the factory, torque wrenches are not accurate under 20% of their max rating. Above 20%, they become increasingly more accurate up to their max.

At 30 ft. lbs, a 1/2 inch torque wrench may be off 3 or 4 lbs.

 

(I used a 1/2 inch torque wrench to set my oil drain plug last oil change. It leaked oil everywhere. I finally broke down and bought a 3/8 inch torque wrench with a lower max rating, and discovered how far off my first torque wrench was at that low setting. I ended up going through my truck and re-torqueing perhaps 100 bolts.)

 

Yea as far as leaks go I broke my plastic oil filter housing first time, was over tightened by dealership and couldn't get it off. That's why i was scared to put strength to it this time too.

I just use wide and depth oil pans, they look like cooking pans almost and work great, no more oil spilling all over the place.

I am just now starting own maintenance so lucky to see and learn from other peoples accidents/mistakes

 

What are you used to working on? I've been working on Japanese cars for 20+ yrs and 14 is SUPER common. It's 13 and 15 that are uncommon. Usually if you come across a 13 or 15 it's some kind of aftermarket garbage. If you have 8, 10, 12, 14, 17, 19, 21, 32 you can usually take apart 99% of any Japanese car. Although this is changing now as more and more manufacturers are utilizing much more hex and star/torx.

 

Get yourself a six point 14mm if you don’t have one. I have sone twelve point sockets but rarely use them. Also if you have a stock skid plate get a six point 12mm for the four bolts holding it on.

 

Mostly C5 and C6 vettes, GMT800/900, 04-06 GTOs, Trailblazer SS, Porsche macans, 79-04 mustangs. So yeah, nothing even remotely jap unless you count my 04 Civic SI 20 years ago.

 

Do yourself a huge favor and get a good quality 3/8 and 1/2 " ratchet, 6 point metric and standard sockets, and metric and standard combination wrenches. Cheap tools aren't worth it on your skin and joints. And you can hand down to lucky others. Good tools are like jewellery to anyone handy.
