Big SNAFU need help assessing

Should have use a left threaded drill bit so if it grabbed, it would have backed out.

 

would o' could o' should o', don't help now does it, yep maybe next time.

 

This can work….
At least get it started then use a left handed bit to continue your effort and then a easy out..

 

Good suggestion, but the sensor is non ferrous

 

This is what im going to try..the difficult part will be clearing the end of all the grease that was on the inside of the sensor

 

Oh yea..
Be carful not to flip the sensor end in the cavity,,,, maybe Q tip.

 

Looks like brass or something to me, thought about that too

 

If its as thin of aluminum as I'm guessing, you may be able to poke a hole in it with something stabby and then work it out with a dental pick.

 

I work for a company that makes surgical instruments, so I have all kinds of fancy picks and forceps. If I couldn't get it out with one of those, I'd do what BRO suggests.

 

Good luck, OP! Hope you find something that works!

The other night, I literally thought about how I'd handle it if I accidentally dropped something into an area like that. I like to go to bed filled with anxiety! lol

 

So you think push it in and don't sweat it as well?

 

Yanno, strangely enough I got an uber later on amd got to talking to the driver (he also does his own work) and he wisely advised not to worry about it, that he has worried a lot about these sorts of things and it never did anything!

 

Find a welder with a very steady hand. Have him tack the end of welding rod to the sensor that you can see. That tack will be strong enough to hold it while you very patiently thread it back into the mounting hole. Back it all the way out once you get the threads started.

If it's brass, your welder guy will have to be amazing at brazing.

Seeing how you're working through this tiny hole, maybe find a welder who is also a gynecologist...

 

I don’t know how bad off you are without use of the truck. It doesn’t look like there’s enough room to stick in another sensor with the broken one right there. If you need it badly, you could plug the hole, maybe with the old sensor, if it wasn’t leaking. You’ll need to file it down so it’ll fit, then hopefully not breach it’s ability to not leak. Or plug it with something else.

 

Always, Always, Always, use a reverse drill bit on drilling for an easy out. 1.) The reverse drill will a lot of times turn out the broken bolt etc... 2.) In a blind hole either it will bottom out and tighten the broken piece or drive it into a blind cavity.

I hope you find a way, but I think unless you are a lottery winner that head needs to come off for a proper fix.

 

Perhaps a urologist is more in order?

 

Coming up on a week now, did you get it repaired? What fixed it? Did you have to pull the head?

 

Hey, thanks for the follow-up. After seeing enough members saying leaving the sensor end in the water jacket being an option I decided this was a decent option as if it did cause an issue with coolant flow I'd see the temperature go up and I would need it removed. (wouldn't be in a worse position than I was in) But first I was going to try and remove it using JB weld and a modified screwdriver that I dremel'd up.. so I got everything together but when I went out to the truck the sensor had fallen in entirely.
So I proceeded to mount the new ect but then noticed while reattaching the throttle body that the coolant bypass pipe had broken. So I ordered a metal upgrade pipe and waited for delivery.. I managed to get it mounted.. good thing I had to replace it.. turns out the other side was leaking coolant and the part was so weak it broke with ease while removing... so... got the rest of the truck together.. went to turn it on and it seems I drained the battery somehow in my multiday repairings.. charging battery later today and hopefully she starts back up, then I'll be doing a full coolant flush tomorrow or the next and I'll be able to report back on how everything is.
One thing I do need to do is buy replacement vacuum hoses so I'm on the hunt for those.. I'm having difficulty finding them in the 2nd gen tacoma parts list .pdf I got from here.

 

Vacuum hose is somewhat universal, available at any auto parts store. You could yank one off, bring it with you, then ask for more than you actually need, it's cheap. Except for the one that attaches to the pvc valve, that one is formed, but still replaceable with universal hose.

100% agree with this. Don’t do anything. It will settle itself in the block and stay there
