ok, so i started at the flies mod and ended up pretty much stripping the last screw.:( such a tool... doh!!!

i have read guys using a dremel to cut a slit to use a flat blade to remove the offending fu$%ing screw but was looking at ways others have used to free the demon screw.

by the way... i don't have a dremel and would rather not buy one for one job.

any ideas guys??

cheers
 
lots of heat with a micro torch. #0 screwdriver, i bought a brand new one, and tap it into the screw with a wrench or whatever until it wil break free with h=enough heat they pop out easy
 
Probley wount help now, but when i did mine I put the bit in a extension then put it in my drill and turned the speed down so I could just worry about pushing down with having to turn the driver. I was able to get them all out without heat.
 
Micro torch, micro torch, micro torch and a new screw driver are your friend. That cannot be said enough when doing this.

I did have one that was a total bastard and had to use the dremal. Be careful using the dremal and still use the micro torch and heat the screw before removing. A dremal is a handy tool with endless use's
 
yeh, i did buy a new size 0 driver and heated with mini torch for the same length of time as all the others but the last screw was a total a$$ and messed it up with nothing for the driver to grip to.
got a new dremel type tool coming so will be cutting a little slot for the flat blade.
fingers crossed it'll do the trick.

i did read a horror story with a guy who's dremel slipped and took a chunk out of the spindle... I WON'T BE DOING THAT !!!!!

Make sure you heat the screw enough to see a puff of smoke. I can't stress this enough.
That will be the loctite burning away and will make removal a hell of a lot easier.
 
Just another tip. Before you start to dremel, seal the fly to the throttle body wall with painters tape. When you are finished dremeling use a vacuum cleaner to remove debri before removing the tape. I dont thing the shards will do any real damage if sucked in but why take the chance.
 
I stripped two of the screws using a brand new #0 Phillips and lots of heat from a butane torch. Some just seem to be hard to get out. I bought a Craftsman screw out/drill out extractor and it worked great! I was surprised how easily the last 2 came out. I would definitely recommend going this route before using the Dremel.
 
I used my soldering iron to heat them up. I then used a #0 phillips and tapped on the end of the screwdriver with a small hammer while I attempted to back the screw out. It was a PITA, but this trick worked.
 
I used these from boltdepot.com Product #6852
Metric machine screws, Phillips flat head, Stainless steel 18-8, 2.5mm x 0.45mm x 5mm. I ordered 100 of them because shipping was the same price. I'll mail you some if you want just send me a PM.
 
I've mentioned this before and just about everyone disagreed with me.......but I'm stubborn.:) Heat is not a good answer in this situation. The screws are stainless, which is already a very soft metal and they are very small. Heating may burn off the loctite but it also softens the tiny stainless screw even more.

I've probably read a hundred post's on both forums of guys that heated the screws and then proceeded to strip at least one. ( usually more )

Your much better off getting a new driver of the correct size, lining it up carefully with each screw and giving it a 3 good smacks with the end of a larger screwdriver, on the third rap also turn the driver. ( just a firm rap, dont over due it ) The shock/vibration will break the loctite free AND get the driver seated into the soft stainless screw. The screwdriver will actually stick in the soft stainless after you do this.

That's how I removed mine and it worked like a charm. This is what I've ALWAYS done for small fasteners that have loctite on them.

SAVE THE HEAT FOR LARGER FASTENERS, ITS NOT THE WAY TO GO WITH
tiny, SOFT STAINLESS SCREWS.
 
tried the dremel and no chance is that fecker coming out so iv given up. :'(

booked in for a follow up dyno on tuesday.
had one first when i gutted the cat on stock headers plus quill slip on.
now i got a mivv gp and arrow headers (muhahaaa) so hopefully with a good tune it'll wake her up a bit low and mid range anyway.
will post chart once it's done. :D
