Advice for removing EGR tube on a KA24DE

[Arro]

Trying to remove the EGR tube from the OEM exhaust manifold...



Adjustable wrench just barely started to slip and round... not bad tho. That sun'biotch is on tight! What size is that, what's the best wrench to use (box, open, ???), penatrants, whatever...?

Also, I bought a KA24DE header, but I see the EGR port is pointed differently...



I imagine many of you have dealt with this, how did you do it? Bend the stock tube?

Any help greatly appreciated.

Ill be honest with you and share my ridiculous technique for getting that mfer out.

I attach vice grips to it as tight as they will go. (who cares if the bolt collapses or rounds, it's going to anyway)

And then I get a big a** hammer, and whack it as hard as I possibly can about 6 times. Then it breaks free, and I smile.

^^^ umm kinda, use vice grips and dont get them as tight as you can, get them snug enough to where they wont round the nut. the you can use heat and penetrating oil on the manifold/threads. you can try bumping the vice grips with a dead blow or rubber mallot, but dont do it as hard as you can.

as for the header, it looks as if its for an s13 and you have an s14. i think you can get an s13 egr tube to make it work... not too positive on that one though. use anti-seize to re-assemble any exhaust bolts/nuts

hell mine came off easy. I think I used some pentrant first but I got it off with an adjustable crecent no prolblem.

if you hit just the part that screws in with an acetylene torch, then let it cool it may loosen. it can expand forcing the area around it to also expand, then as it cools it will contract. if you don't heat up the area around it as much that part will not contract and then it should be looser. although I'd try the vise grip thing first.

or another idea, if your not going to use it, cut the tube off with a hack saw then use a properly fitting socket and breaker bar.

Ok, I'll try some penatrant, a torch, and some vice grips. I also need an S13 ERG tube it seems, this header is for an S13 KA24DE, and I have an S14 KA24DE.... so my tube doesn't have a 90-deg. bend into the manifold, mine goes in at an angle.

Anyone have an S13 EGR tube? I could really use one.

I would just remove the EGR system as a whole. Then you can just cut the tube, install new header and plug the hole with a bolt.

[sleepersilvia92]

yea im with zach-ka just ditch the whole system if u can loosen that bolt cut the flare off the tube and put a nickel in the new header and thread that egr bolt into that ive done in a dozen 240's with no problems sounds funny but its the nissan nickel trick the s14 i bought they didnt take the egr valve off just put a nickel there and threaded the end back on lol good luck

[Arro]

lol did either of you notice my location? I'm in California and I'd like to have working EGR.

So yeah, I need an S13 KA24DE EGR tube.

lots of pb blaster! let it soak for a while then soak it again. best thing to use is a line wrench, but im the only one i know of with that size. had to special order it from the snapon truck.

I did mine with vice grips, hammer, Kroil, and a can of compressed air. The bolt rounds really easily, so a wrench was useless (and now that I used vice grips, the bolt is round ). Anyway, I applied Kroil and let it sit for an hour or two. Then the vice grips. Took some time to get the vice grips right; they had to be pretty tight before the would grip the bolt when I hammered. I hit the grips somewhat lightly because I wanted the tube in good condition. No movement for three hits, then I nuked the bolt - not the header - with a long spray of inverted compressed air and the next hit - yes! - about 5mm of movement. Took about 45 min to get it off. Most of that was little micro turns with the grips. Now it's slathered with anti sieze.

Fyi for every one that likes ”pb blaster” the active ingredient in it is a product that justice brothers created. The stuff justice brothers sells has like 10 times the active ingredient and is called jb80..... Stuff will break any bolt loose with ease. If you can't find anyone that sells justice brothers, parts stores sell little packets of stuff called mr penetrant that also works extremely well.

[compactfean]

Also, before attempting to loosen...... Hit it! If you tap it with something steel sometimes it helps break loose the threads a bit before you try and put a wrench on it.

heat the exhaust manifold with a map torch, when its hot the egr fitting will loosen easily.

[nismo silvia]

The egr tube just cut it then get a socket on it as for a block off plate as long as you disconect the vaccume to the egr valve it will not open so there is no need buying a block off plate. Unscrew the tube and throw it away.

And no one noticed the age of this thread...

2 years it could still be in a project state lol
