Welding on the chassis of a computerized Porsche

Sometimes it becomes necessary to weld on the body or chassis of your Porsche. This would usually be part of a repair following an accident but could also be non accident related repairs or modifications that would require welding to be performed somewhere on the car. We are specifically concerned about using the different types of electric arc welding. These include Stick, MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding also known as Heliarc welding. All of these electric arc welding types use electrical energy (either A/C or D/C Voltage) to generate extreme heat at the localized spot where the weld is taking place. As part of the welding process, an earth connection (welder ground) is made near the welding site to isolate and collect this energy during the welding process; however, not all of the electrical energy will necessarily take this path. High frequency electrical energy can be introduced into the car’s grounding and wiring systems through th ... read more

Porsche Interior Water Intrusion

Water intrusion is one of the few unnoticed killers of the modern automobile. All modern Porsches are even more sensitive to water damage because of their many delicate electrical control units and computers. I remember this all started years ago when Porsche issued a service bulletin on the 924 to re-route and seal the antenna cable because water could travel along this cable and find its way into the central electrics panel inside the vehicle and create havoc with the electrical system. The main area to watch for water collection in the 986 thru 997’s is the front cowl area. The front cowl area is located just below the base of the windscreen and has water drains on both sides of the battery. There are two front cowl area cavities where debris such as leaves and dirt can collect and in time clog the front cowl drains. When these drains clog water will accumulate in these cavities and at a point migrate into the interior compartment of the vehicle. Water ... read more
