how do i remove egr pipe from the valve?
 

so I'm trying to replace my egr valve.

how do I disconnect the pipe from the egr valve?
I'm in california so I'm trying to do this to pass smog.

Take the whole egr valve off with the pipe attached so you have space to work. Get the huge wrench you need for that, heat it up with a torch and twist it off real quick...shouldnt be too hard!

Its really fun! Just like the heater core hoses

Good luck

the bolt on the pipe is rusted. i used a 24mm and 23mm wrench. neither worked. 24mm was too big and would just start to grind the bolt. 23mm is too small..
now what?
i just changed the BPT valve and now my idle dips super low, almost stalling.. dont know what could of gone wrong..

I actually usually use a standard size wrench to take that nut off.

As for the stalling..vacuum leak? idk.

whats a "standard size" wrench?

the car doesnt' actually stall.. it only happens when im driving and i drop the clutch. Instead of returning to idle, it'll just drop below where it'll almost stall and come back up. I was thinking a vacuum leak too..don't know where though..

sprayed WD-40 the night before, removed other parts in way (including hood), used adjustable wrench got an angled that would allow me to put all my weight on it, and gave it a quick jolt, boom got it off, at first i was going to remove the entire intake manifold but took a sandwich break and was able to take this badboy off. just get in there and start wrenching playa!

ok soooo..

i eventually got my egr switched out..ended up just undoing the pipe on the egr side.
but...
the exhaust side got sprayed with 'liquid wrench' and wd40..and now i think theres a leak there..
after driving for a bit, the engine bay will get hot(hotter than normal) especially on the exhaust side. I can put my hand on the hood and it'll be hot. it'll get warm near the pedals if i'm driving on the freeway for awhile.

how can i fix this? is there a way i can add something to maybe "close" this leak?

is there any kind of flexible pipe that will withstand the heat from the exhaust in replace of this metal egr pipe?

i want to cut off the egr pipe completely and just put it some kind of flex pipe so it can be adjusted.
