Ford 1920 Injector (Sounds like exhaust leak)

[gdabel]

I sold a tractor that had pressure coming out around number three injection at the head. Sounded like a exhaust leak. The buyer purchased anyway. What would that be? Thanks

Sounds like the injector isnt sealed off. Was it fixed by a fly by night tractor jockey? The description is vague. the other posibility is head or head gasket. Its sold so its gone.
