crack in head?
 

there is cracks in my 89 head by the valves were the injectors come threw should i use this head or find a new one?:argh::s::humm:

Yours and every other Cummins head on the planet.

It'll probably be a problem after another few hundred thousand miles.

depends how deep/wide they are.cummins has these pics in their manual.

Your fine unless you can see through them. The non-I/Ced heads (like yours) do it worse due to the larger injector holes.

Great, Goldie non-I'C'd:argh:

it is SERIOUSLY nothing to worry about, the crack show up VERY early in life and do no harm...
