Customer Question

I have a 2008 Mini Cooper Clubman with 200,000 Kilometers. It began running rough and after investigation it was determined the rings had failed on Cylinder 1. The engine has been rebored (to eliminate scratches from dmanaged ring), new pistons and fully rebuilt. It starts and runs fine up until it reaches 90 degrees C and then starts to run rough. Any ideas on the cause?
