Make small glow plug for diesel engine : Is it possible ?

[metalmangler]

Some full size diesels used an exposed element glow plug mounted in the inlet manifold to heat the air in the manifold, rather than inside the cylinder itself.

Both my 1960's Ford 3000 tractors had this, and they would start in any weather, provided the battery was in good condition.

Why not buy a glow plug for a Terex 33-19 truck.
