M12 x 1.25 thread repair

[bowlofturtle]

Did the oil change on my father's camry. Someone screwed up the drain plug. It took way too much force to remove.

When reinstalling, the last parts of the threads are really tight to install...

I'm looking for a thread chaser/cleaner to try to repair this...

Or should I just get a tap and make new ones.

Not sure if you want the tap or the die.

Also might look at this set, so you're covered for most sizes in the future.

A lot of times you can just replace the drain plug. They usually deform before the pan

Hands down the best thread repair available. I used their kits all the time when I owned my machine shop. http://www.threadkits.com/time-sert/drain-pans/kits/1212c.html

Any autoparts store should stock the oversize self-tapping replacements. A few styles available.

Try running a standard size tap through it first. You may have some mashed threads that need straightening. If the hole feels loose after that, then you can look into the thread repair or oversized drain plug. If the hole feels tight, you're good to go.

The Craftsman thread repair kit has the tap and die both for that size. It would be a good excuse to buy the set if you don't already have it.

Not a good idea to use a tap to try and chase a thread, that's what thread chasing taps are for.

Agree; I'd start with the easiest, and safest possible solution. If a new drain plug doesn't solve the problem, you can always go to Plan B.

i work in a lube shop, replace the plug 99% of the time that will fix it (i have probably replaced about 6-700 drain plugs)if that doesnt work use a thread chaser, much easier and really hard to mess up. its easy to **** a tap slightly in the hole and ruin salvageable threads. dont go oversize unless you really have to, its a pain in the *** as the threads it creates are ****. id rather replace the oil pan before id go oversize (if it was a car i was keeping)

Man I picked this kit up and love it.

I've used it for everything so far I can get my hands on. Other then the drain plug that I bought it for. Lol

That m12 1.25 is so freak common on imports.

Gotta wait a few months for that.

best options

1. make sure it is the plug and not the pan.... this will be the cheapest

2. if it is the pan try to salvage the threads with a thread chaser

3. if the threads are not salvagable using an oversized self tapping plug is cheaper/easier but the worst idea and any lube shop will hate you for it... either get a new pan or redrill/tap to a common 14mm plug size
