Breather pipes from the rocker cover are usually fed into the throttle body & into the inlet manifold where toxic oil fumes from the engine are burnt (bloody hippys), over time the throttle & inlet manifold can become lined with oil sludge.

I cleaned my throttle body with carb cleaner, cleaned out nicely with no effort at all, then I directed the largest breather pipe into a catch tank (afterall there's no point in cleaning it if it's only going to get covered in oil again), & blocked the rest of the pipes.

if you have done the breather mod then the problem should not have come back for many months at least
