Lancia Thema 16v Turbo heavy on fuel

[Johan du Plessis]

Just over a year now MY lancia received a new head with brand new cams,valves etc. The old head got thrashed (all 16v bent when timing chain broke) since then I replaced the head myself and took It to the agents the reassured and told me I did the job perfectly and they gave it a final check plus tune-up


What may the problem be when the car uses A full tank (70L) in plus minus 500km
