throttle bodies

[Dans92cb7]

i wuz wondering if the a1/a4/a6 have the same throttle bodies? because i have a a6 now and the idel screw keeps backing out some how and wanna replace my a6 with my a1 that i have and maybe port it why im at it...

Couldn't you use a mild form of loctite or other threadlocker to prevent the screw from backing out?

what i did wuz drill a little hole above the idel screw and placed a peace of medal in the hole to hold it from backing out..bit it looks like shit and i have a extra a1 throttle bodie that i could put on but idk if there the same as the a6

Get otu a ruler or mic and see. THey might be siffernet but I doubt theres a major difference other than maybe size.

here is how you FIX the problem and not rig it, screw it up...get some tranny pan liquid gasket...if you get stuff meant for oil pans it will be too hard and you will get it stuck...same with locktight.

The tranny stuff stays...a little gooey...has give even dry. This will allow you to adjust it if you need.

Follow the procedure for setting your idle with the rtv on it (liquid gasket) and you will be fine...worked perfectly for me...no drilling...no screwing stuff up.

thats a good idea...so can u unscrew the screw all the way out and put rtv on the treads... and re screw it back in

Some Loctite may well make the bolt stuck for good. But they make multiple varieties of the stuff, including some for low strength applications

Any hon hardening gasket goo will probably work. I used Lotite Aviation Gasket No3 for this (used to be Permatex Aviation Gasket No3) and it was perfect (still is after three or more years, never moves, never have to think about it...).

Don't use any of the Loctite thread locking compounds for risk of really sticking it, but their 'Bearing Mount' compound would be OK (same sort of stuff as the thread locks, but not so tenacious).

Hmm I should do this, as it seems my factory applied goo has come loose and my idle keeps getting screwed up

yeah my car just keep reving up and down..so i replaced the ftiv and the other thing and that never worked i looked at my idel screw and the damn thing wuz almost all the way out screwed it back in and bam solved the problem... i figured i wuz the only one having this problem guess not...so does anyone know yet if the a1 and a6 throttle bodies are the same

From memory there's an O-ring on the screw that prevents the screw from moving from it's set position. This O-ring gets old and hard and stops doing it's job, replacing it should fix the problem. I used gasket goo because it saved me making a special trip to source the O-ring. This was supposed to be a temporary fix, but it worked so well I haven't yet bought the O ring.

yes you can take it all the way out. Mine seemed to have some...tube or something on it too...maybe an old sealant of some sort???

the o-ring was old on mine as well...you could prolly get an oring for dirt cheap and it may fix the issue, if not, then try this method.
