Hope i've put this in the right place. I'm in need of a good engine builder that's local(ish) to put my bottom end back together for me. I'm based in Hemel Hempstead and the engine in question is a low comp Pug/Citroen 1.6 16v.
Phil Crouch in Chorleywood / Rickmansworth is an excellent engine man, mainly BMW M's, but worth a shout. His number is 07960280953. Not the cheapest but does an excellent job.
