A friend has just picked up a Carisma 1.8GDI for a couple of hundred quid and I notice on HJ review it mentions about carbon build up in the engine.
Would Seafoam motor treatment or Ecotek Power Boost help?

For a couple of hundred quid, if it runs OK, I'd leave it well alone.

True.
He could probably get a refund on the 11 months tax and get most of his money back!

The rock-hard carbon builds up in the inlet tract; so no whizzo product will touch it.
The head and manifold need taking to a specialist cleaners - crushed walnut shells are reputed to be quite effective.
