Removing nuts from front header pipe

[Doc Pete]

I can't seem to remove the 3 nuts on the manifold that hold the front header pipe.
I have a 92' FWD manual 4cyl. standard bed pickup. Any directions would be appreciated. I ain't dumb, just never done it before..............

Soak them PB Blaster for several heat cycles, then you need a loooonnng extension on a ratchet with a deep 14mm socket. They are a one use nut, you should replace them with new ones.

Thanks for the help. I believe they must be rusted and fubar. My 12mm long socket just slips around the nut......

Most of the time I just break them and replace the studs and nuts.
