3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Ok so I was trying to replace my IAC gasket, I got everything off but when I got to the 4 screws, 3 came out, 1 didn't I ended out sorta grounding out the head, so I went to Home Depot and got a 12v drill and a stripped head remover and drill bit for it, today after letting the battery charge I drilled a hole and I thought I got it in there but then I started to turn the scew remover and the tip broke off in the stripped scew ((((((((((((:headb ang::headb ang:

Is there enough of the bit sticking out to grab it with something and twist it back out? If not, you could take a small cut-off wheel and slice a thin notch into the top of it and try and turn it out with a screwdriver.
The screws that Toyota uses are just too soft. One of them is bound to get rounded over in the phillips head no matter what you do. Here's how I get them out.
Get a small vice grip plier. The larger ones won't work, there isn't enough space to get a grip on the head. From your description the easy out is broken off in the screw, so the head should still be there, and there should be enough room to get the vice grip pliers in there. Clamp them on as tight as you can get them. Then a quick counterclockwise yank, and the screw should break free. Once it does, you can back it out easily.
I like to replace the lame phillips screws with either socket head screws or cap screws. The thread size is M6 x .80 x 16mm.
Persistence pays! They say vice grips are never the right tool for the job, but in this case, it probably is.
^excellent picture btw
Thanks, and you are right about persistence. Your idea about slotting the screws is a good one too. But you need to be real careful if you do it that way. If you make the slot too deep the lame metal that they made the screws out of just peels off and you are left with a half moon screw head staring at you. And then you have to break out the vice grips to get that off.
Another way is to just grind off the head of the screw completely with a cutoff wheel in a dremel. It's a bit tight and you have to use a small cutoff wheel and be careful not to damage the casting of the IACV. Once all the screw heads are ground off, you have to get the vice grips out to remove the screws from the throttle body.
So I just bypass all of that, and use the vice grips as step one. I don't even bother to try to unscrew them using a phillips screwdriver. Clamp and turn, that's my motto when it comes to these PITA screws.
One word of caution though. If you replace the stock screws with socket head screws, don't over tighten them. You don't want to strip out the threads in the throttle body. Just put a little blue Locktite on the threads, and cinch 'em down, not too tight....
It's too late for the OP, but impact drivers like this are just the ticket for stuck phillips head screws. If there's enough room to use 'em, they'll loosen screws that nothing else will. And they're pretty cheap, even the good ones.
You hit the end with a hammer and an internal cam twists the bit. So it delivers an impact thrust and torque simultaneously to the bit.

well I bought vice grips today i got the 7inch curved jaw ones hopefully their not too big going to try in the morning, praying that it works so I can use my IAC gasket :P and curious at how bad the iac is
If you decide to disassemble the IAC to allow for better cleaning, I'd moderately hammer the screws (indirectly with a screwdriver). Same with the brake rotor holding screws on some cars. It usually helps, like BMR said with impact screwdrivers.
Also check out the tool specials coming from Sears on Black Friday. I like the flat jaw ones especially for holding some struts rod ends (not the rod body itself). Harbor Freight has a 10" one for $2.99 now, but it's curved jaw.
