Hello Everyone,

I’ve been planning on having my fuel injectors professionally cleaned and finally got around to removing them today. There’s a lot of gunk in the holes of the intake manifold were the injectors seat. The gunk looks like a mixture of sand and oil. I need to clean it but it’ll be difficult to remove the gunk and not let any drop into the intake. I imagine any that falls into the manifold will end up in the combustion chamber.

How sensitive is the chamber to a few small pieces of gritty oil (about the size of a ball point pen tip)? Any suggestions on how to clean the holes short of removing the intake?
