Cylinder Head Studs and Hardware |
| As the displacement of the 911 engine increased over the years, the increased stress caused by differing thermal rates of expansion often caused the head studs to break or separate from their mount in the case. This often resulted in a leak between the piston and the head. Porsche decided to solve the problem by using Dilavar studs. However, there were reports of these studs breaking under pressure prematurely. There are a few good solutions. You can replace your studs with the standard Dilavar studs that the factory began using in 1984. Or you can use high-strength aftermarket studs (available below). Made from high tensile strength steel, and combined with time-serts placed within the case, you should no longer have any problem with head studs pulling out. Another alternative is the factory replacement for the Dilavar studs, which are micro-encapsulated steel studs. These are coated to prevent the surface corrosion that is believed to contribute to the premature failure of the Dilavar studs. |
