tough EGR passage/nut
Posted 30 July 2003 - 06:25 PM
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!!!

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?

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

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

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?

thx & wish me luck.....
