Found my drain bolt to be stripped inside of the aluminum oil pan. It's just spinning inside of the hole and won't come out lmao.
Went to a toyota dealership to have them take a look and get a quote on fixing it.
Upon arriving one of the guys were thinking the threaded hole could be upsized and I would just use a bigger bolt. He went and talked with some of the techs about getting it done. He came back and said that the pan will need to be replaced, and it cannot be upsized. I also was told nothing will be under warranty.
Has anyone came across this issue and what have you done to resolve this.
Have you just upsized the hole and drained it a few times to get shaving out. Or have you replaced the pan. And what's the process for either.

If you take it to a proper mechanic/tech or a repairer that has any engineering ability at all then you have any number of options for a good repair without dropping and replacing the pan. The 2 most common are Helicoil insert and a Timesert insert. These 2 options are often used in applications from brand new on some machinery. There is no way in hell a Toyota dealer will do either of these because it's simple "engineering" and not only do they not have the necessary skills, basic as they are but they are also not in the business of repairing things. They are in the business of replacing things.

Thanks for the reply. I've been searching forums and have seen the time sert option quite few times.
I think I'll go ahead and get a time sert kit and do that hole myself. People say using grease on the taps will help to get all that metal material from going everywhere. Then I'll go ahead and throw a bit of oil through the system a few times and let it drain out.

No way in hell would i be doing that, yeah you could use grease, but all you have to do is miss some swarf and your fucked....drop the pan and do it right.

Yea you right about getting it done right. I was thinking about it earlier and went ahead and bought the new pan. Gonna be shipped in sometime next week.

My oil drain happened to get stripped also. Before replacing the oil pan, I thought I’d give this oversized bolt a try. I’ve haven’t had any issues. Made sure to clean up the threads as much as possible and then ran some cheap oil down the motor to clean the pan out.

Same exact situation. I tried to tap the next size thread and still had an oil leak. Tried to JB weld it and it still leaked. Sucked it up and got a new pan, paid somewhere like $1900 something in total. Labor fees was $960 by itself. Looking back, I definitely got scammed cause they charged me $160 for their 0w-20 oil and that's without including an oil filter.

This is completely wrong. The process I have outlined has been done literally millions of times over the years on all types of engines. Even if there is a small amount of material left in the sump it will stay there and be flushed out during the next oil change. For aluminum to do any damage it would need to get past the pickup screen and the oil filter first. I've changed oil on many many new engines and as always inspected the dumped oil from the factory and I can tell you the amount of times I've found machining swarf in the oil from engine manufacture is in the dozens of times with no ill affect. It's is quite common. You will potentially create more issues from the dealer techs dropping and replacing the pan than a simple, common and straight forward helicoil or timesert repair.

Another good idea. Or drill and tap to the next oversize. Easy and simple you just wont have the std drain plug anymore if that bothers you.

Somehow, I agree with Phil again.

I am aware of this, still not comfortable doing it half ass... Not trying to be confrontational or an asshole, just the way I am.

No criticism here. I 100% understand.
