Arrow Replacing injectors. Have a few questions.

I am sort of rebuilding a motor that has been sitting for a while. I am replacing the injectors in it because the PO said that when it was still in the truck, it needed injectors.
I drained the fuel rails before I pulled the injectors but there was still some oil and fuel that ran down into the cylinders. How do I purge that out so I dont get hydrolocked.
Also when I pulled the old injectors out of the heads, the fuel had varnished up a bit and sort of looks a little brown and rusty. Do I need to clean out the holes where the injectors go into? And how do I do it?

Thanks guys.

To clean it out, I would just take an emory cloth or somethin and rub it down and maybe spray a little brake clean, but not too much. As far as oil and fuel in the cylinders, remove the glow plugs and crank it and it should get the majority of it out.

you can also get a small tube and sifin it out. if you pull the glow plugs and use the starter to crank it, be prepared to degrease the truck. it sprayes it everywhere.

I just turned it over by hand and I guess it got a little compressed in one of the cylinders because now I have a nice black stain on the cieling of the garage. Seemed to work out quite nicely though.
