Today was cam rack assembly day for a 1970 Porsche 911T. One of the most important aspects of the assembly is the speed at which you can perform the assembly. The requirement for speed is based on the use of Loctite 574 sealant between the cam rack and the cylinder heads. In order to improve your speed and ensure a good seal, ensuring the integrity of the fasteners is of the utmost importance. The worst thing that can happen during assembly is finding out that you have a crossthreaded stud AFTER you have applied the 574 and set the rack in place. The video shows an easy way to avoid this common mistake.
It also helps tremendously to lay out your tools and hardware before you start assembly. All 15 nuts, 3, barrell nuts and 18 spring washers in neat little rows. After all, you don't want to leave extra hardware laying around anywhere when you are building engines! Don't forget to also layout your tools so they are within easy reach. You will need both a 13mm socket and an 8mm allen to tighten the hardware. I prefer to run all of the hardware down finger tight before I pickup the torque wrench so I have a T handle in front of me in addition to a torque wrench preset to 25NM.
