Unfortunately there are alot of special tools required for doing major service on BMW's due to their complex designs and assembly procedures. The tools normally cost hundreds or THOUSANDS of dollars and dealers are usually the only technicians to have them. I am a trained mechanic and hate having to pay people to do service on my car. Because of that, I have bought the tools needed for a job whenever I have needed to do it.
This kit includes ALL of the special tools required in order to remove the head in order to replace a head gasket or any other major overhaul on an engine. Also by renting the tools, you will get to contact me anytime regarding questions on the procedure.
