Had a bit of a problem, the engine that had run perfectly on the drive was cutting - backfiring - & emitting a huge cloud of smoke - then carrying on, but only when under load. I think I've traced it to the emissions system. I plumbed the sump breather into the inlet as the good Ford intended, then some time later I found an old breather filter that fitted on the stub on the cam cover. Of course under load that means that air comes in through the breather filter, down through the engine & into the inlet via the sump breather, carrying a load of oil with it. Duh!

Anyway, I think it's all sorted now so as soon as it's taxed I'll be back to a two kit car person
