Can the PCV system be cleaned.

Hi all, as the title suggests really.

The smoke problem has returned with the t4, puffs of blue when you change gear on boost and quite a prominent amount on the overrun once you touch the throttle again.

I was suspecting turbo seals, but today while awaking the car from its two month slumber (water pump has gone, it's going to the garage this week) it occured to me to open the oil filler cap with the engine running, and there was no need for the glove test as it's very clear that it's blowing instead of sucking.

From what I can see it's a case of removing the inlet manifold and a few ancillaries to get to the heart of the system, so I'm hoping there's a chance of just soaking the whole lot in some sort of solvent as well as clearing all the associated pipework then hopefully it'll work again, or will I need to buy new parts, as I'd much rather the former as opposed to the latter, for those of you that have followed my escapades on this board you'll already know how much of a money pit this thing has already been lol.
