What’s the safest way to cleaning the injector bores on the intake manifold wile the intake is installed on the engine?

Maybe a nylon round brush with some solvent
Then blowing it out with the compressor.

i can't believe every one pulls out the intake manifold to clean the injector bores.
or
that nobody cleans the injector bores on the intake manifold when replacing injectors.

I would think that a small detail brush and or firm tooth brush, some penetrating solvent or simple green undiluted combined with a shop vac would knock this project out with authority. No matter what, the shop vac would be mandatory to me.

I just sprayed brakekleen. :biggrin: Worked like a champ. No problems here.

Compressed air in each port before pulling the injectors. Spray some brake cleen to loosen the dirt.

I just clean the o-ring seats with a solvent (Prep-Sol) and q-tips, then WD-40 the bosses before installing the injectors.
