I also loaded the bolt photo I can not loosen from the engine block.
I'll have to drill everything and remake the thread
you know the size of this bolt ?
thank you Giacomo

Giacomo,
If that fitting is in the intake manifold just below the carburetor as
in your photo that should be 1/8" NPT pipe thread. I hope that is a pipe
plug threaded in there and not a bolt.


Good luck getting it out. Be careful. The intake is cast and can be damaged
easily.

Take care,

I'm sorry it is not a bolt, but pipe plug threaded ,then as it is blocked and I have to remove, I try with a heat gun.
but after to make the new thread I have to buy a 1/8" NPT male thread
cutting ?
thank you

Hi all,

no one knows how to tell me how far is the threaded pipe plug ?
1/8" NPT ot 3/8 UNF ?
thank you

Giacomo

It all depends on whether you are able to extract the plug
without damaging the threads in the manifold.

If you can get the plug out without damaging the threads
then do not use tap but a thread chaser. A tap will cut more
material whereas a chaser will just clean the threads up.

If you can't get it out any other way you may have to drill it out.
Use drill bits in larger and larger sizes until you can insert
a broken screw extractor. If you are concerned about how
deep to drill buy a cast iron or brass 1/8" NPT pipe plug for
reference.

Thank you 4x4M38
if I try to remove the threaded pipe plug with a heat gun there is a risk that the petrol explode ?

Giacomo

It might be a good idea to remove the carburetor and move the fuel line.

You said your previous attempts with a heat gun were not successful. I would suggest you use an oxy-acetylene torch with a small welding tip to concentrate the heat on the threaded plug. As soon as the plug starts to glow red remove it.
