Need to know what size bolt this is. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Removing KA and i've hit a small snag with my wrench sizes which unfortunately stop at 19mm. Removing this from behind headers and don't know what size it is.

24mm x 1.5 thread pitch. Use vice grips to get it loose. You may even need to hit it with a propane torch for a minute to get it loosen up.
Goog luck

Soak the ever living crap out of it with PB Blaster for a couple of days before you attempt to pop it off. If it strips, good luck...

You might want to get a flarenut wrench for that guy.

Always better to grab as many flats as possible.

cut with torch and replace with cheap 60 dollar ebay header.

you mean a line wrench

Your best bet it's to use a pipe wrench because every other wrench will fail and leave you w/ busted knuckles. Good luck

best advice given by yours truly

Pussies. I took mine off with a large crescent wrench and a touch of PB that I let soak for all of 5min :-)

Just kidding- All good ideas... but crescent wrench worked for me... I may have had to angle it so I could push it with my foot; but that was a LONG time ago. Good luck~

EDIT: Disregard- I thought that was the one on the downpipr section, not behind the exhaust mani. My bad. I say do what you can... If it strips, cut it off and plug it.

Or just cut the pipe out of the way and put a 24mm socket on it with an impact.

If you're deleting emissions, that works.

Kingtal0n · 01-15-2014, 10:10 PM

A nickel will fit quite nicely under that, blocking it (on the sr20 at least). We used to joke and say "now your exhaust has inconel in it..."

*e1_griego* · 01-15-2014, 10:59 PM

Works fine on KA too.

A nickel on both ends and one in the AIV as well.

15 cent emissions delete.

DuhChuki · 01-16-2014, 06:04 AM

Thanks for all the suggestions. I ended up breaking that tube... Gonna go with aftermarket headers like sleepyS14 said.
