This is my first post on this forum and I find myself in the unfortunate position of having to carry out major repairs to my 2010 Cooper S. I have zero compression on #2 cylinder and low compression on the other 3. A wet test showed an increase on the 3 low cylinders. Having found this I have determined that at the very minimum I am looking at a valve job and a set of rings. However, I won't hold my breath on that best case scenario. I have not taken it apart yet as I am in the process of ordering the cam timing tool kit but I would be grateful if anyone can tell what if any other specialty tools I will need to carry out the repairs.
