I recently blew a head gasket at the track, when I drained my oil it looked like peanut butter. While disassembling everything I realized that same oil went everywhere, including through my turbo and to my oil pressure sender. I'm running 2 different lines that total about 6', and I want them clean before I put them on again. I figure some residue of whatever I clean them with will stay inside the line, meaning it will end up inside the engine once oil flows through the lines again. Does anyone know of a way to clean the inside of them that won't damage the engine when I go to start it? Thanks.

take em off and blow them out with compressed air. change your oil twice right off the bat when you get her runnin

Brakleen just dont soak it for periods of time as it will make rubber swell.

Blow them out with air if they were filled with air/oil. The compressed air will dry out the water in the lines, and any residual water will be such a small amount that it won't cause any harm. If you want to be anal, let the lines dry for a few days in the sun after you blow them out, then blow them out again.

Really any mild solvent product (safe for the liner material of the hoses) will work fine too, then blow out with compressed air to evaporate the solvent. Again, a tiny amount of solvent isn't going to harm anything. You probably already know about normal fuel dilution in oil, right?

I'd be more concerned with getting the engine cleaned out. The external oil lines are the really easy part.
