hi all im a member of the vxlscc and astra sport, geoff recommended i joined this site so here i am, i am on my second engine as the first snapped the chain, then 1000 miles later blew the head gasket, then 1000 miles later a bolt was found in the engine that vauxhall left there and it blew up, so my car has been throught the wars but im determined to keep it on the road, nice to have a site dedicated to this engine, really pleased that the owner did this,
