Guest shanonsf Posted July 30, 2003 Share Posted July 30, 2003 hey all- firstly, I am victorious in my Emissions War (burtal CA)!! but they won't give it to 'cause my EGR passage is still funked up/clogged........b*=tards disassembled via intake manifold...... i had 2 feet of spinning wire in a 8" pipe and fuel injector cleaner didn't do the trick.. my question: the nut on the head is siezed/real tight, will not budge to remove passage asmbly entirely.........any suggestions on removing this nut- 17mm socket or wrench, heat (torch it for a while),specific lube( mine did do squat), pay the shop $100 p/hr.................. afraid of a nightmare breaking this stupid thing pls help ASAP, the last thing in my almost done emissions war!!! shanonsf 82 GLW Quote Link to comment Share on other sites More sharing options...
Guest Subrina 7 Posted July 31, 2003 Share Posted July 31, 2003 on my Ea82 bypass pipe (one end into intake/other into head, right?) I think I remember using a flare nut wrench after popping off the tin on the tube.. then tapping w/ the ball peen. Good Luck! Quote Link to comment Share on other sites More sharing options...
Guest shanonsf Posted July 31, 2003 Share Posted July 31, 2003 hey, thx for the tip, its the side into the head BTW, but..... whatsa flare nut wrench? did ya tap the nut or the pipe? also how deep does this nut/passage go into the head? thx shanonsf 82 GLW Quote Link to comment Share on other sites More sharing options...
Guest Subrina 7 Posted July 31, 2003 Share Posted July 31, 2003 A flare nut wrench is the kind that is almost closed and damn near 6 sided but is missing a section so you can use it on....flare nuts (commonly seen in brass/copper lumbing, hydraulic lines-i.e. brakes) a cheap set will do (I think I got a 3 wrench set w/ a size at either end for about $10 at schucks/action auto) I tapped on the wrench... some penetrant may help, careful heat might not be so bad but I did not go there. the flare nut wrench is preferred cause it won't round out your corners on the nut Quote Link to comment Share on other sites More sharing options...
Guest x silvershad0w x Posted July 31, 2003 Share Posted July 31, 2003 These little buggers can gall up real bad in both the head and the intake manifold, but I mostly have had trouble with the head-side. Definately go and get the flare nut wrench for the job, a regular wrench, channel locks, you name it, will tear that sucker up in no time flat. I use penetrating oil (PB Blaster), and if that doesnt work I'll resort to heat. You pretty much have to use a hot fine tip torch to do the job the easiest, and heres why- If you use good ol' propane or mapp gas even, the heating effect is much slower, and the heat has more time to pass between the head and the flare nut. By using a concentrated heat like oxy-acetelyne on the head only, it allows the head material to expand, without heating and expanding the flare nut as well. If you heat both objects at the same time, you are working against yourself. And lastly, don't forget to put anti-sieze on it when you install it again. Same thing goes for all dissimilar metal joints, never forget, it'll make your life easier someday Quote Link to comment Share on other sites More sharing options...
Guest shanonsf Posted August 1, 2003 Share Posted August 1, 2003 thx folks that's what i thought a flare nut wrench was, i got some small ones...got some real stuck brake caliper bleeders that heat nor flare wrench have made budge. suggestions? i'll get a flare wrench for the EGR nut.......have propane torch but no Oxy -Aceteline........... thx & wish me luck..... shanonsf Quote Link to comment Share on other sites More sharing options...
Guest oobnuker Posted August 2, 2003 Share Posted August 2, 2003 If it's just the bleeders why not use a deep socket? I think it's 7mm or 8mm if they are original. But you know what I mean??? Nothing beats a socket if you can fit it over... Quote Link to comment Share on other sites More sharing options...
Guest shanonsf Posted August 2, 2003 Share Posted August 2, 2003 I had a socket on there, but maybe more leverage could help (lonjger arm) i'll give it a shot, just paranoid snapping one of these buggers......... keep ya posted & thx shanonsf Quote Link to comment Share on other sites More sharing options...
Guest oobnuker Posted August 2, 2003 Share Posted August 2, 2003 You could also try tightening it - to break it free if it is stuck... Quote Link to comment Share on other sites More sharing options...
