can blocked oil lines be effectively cleaned?

[dummi]

i recall my local turbo shop did this for my car along with recon turbo once and it ran after that for a long time, now i wonder is this a viable DIY job cheaper than new lines £200+ /ubbthreads/images/graemlins/frown.gif my worries are wrong method would damage the pipes so whats the right method

I Would have thought that removing the lines and blowing them through with an airline would do the trick, maybe blow some solvent through after they are clear just to give them a good cleaning
