Porsche 997 Service Specialist
Braunton see the Porsche 997's for routine servicing, four wheel alignment and repair to some of the common faults. Most of the 997's suffer from the same problems as time and mileage dictate. These faults are attended to weekly - Braunton have created a menu price (parts and labour) to allow owners a simple and swift price for repair or for comparison.
Porsche 997 - an outstanding 911 for the modern era - a super sports car that is easy to live with as a daily driver or something special for the weekend. The design evolution of each model has created a gem in the 997 – drop-dead good looks and the pace and handling to match.
997 Common fault repairs: The Porsche 997 suffers from rusty exhaust nuts and bolts - Braunton Engineering replace these fasteners with stainless steel items. 997 Engine tandem oil pump corrosion. Check yours: The pump is situated on the back of the engine on the right hand side (offside), and can be seen by looking up from under the rear bumper. Changing a rusty oil pump is essential - a perforated pump casing will allow pressure and oil to leak. A replacement tandem oil pump requires the removal of the exhaust... If the exhaust fasteners, nuts and bolts have corroded, the time to remove will be extended due to the need to extract the studs with heat.
The 997 engine has 6x ignition coils - these are subject to heat soak from the adjacent exhaust and also road dirt/salt, both of which mean the coil's insulation breaks down in time allowing a misfire to occur. Each ignition coil is mounted to the head by two bolts - these bolts can become corroded and at the time of major servicing (and/ or spark plug removal), easily snap and break off. Drilling out the studs and a recoil of the threads solves the issue along with a new set of ignition coils.
997 coolant water leak. The coolant water pipes feature alloy unions with spring clips. These unions become quite corroded and if left to worsen, the union can separate allowing coolant to leak and a potential engine overheat. This leak can also affect the grip of the car when antifreeze is dropped under the car – on tyres and road surface. There are some noteworthy examples on you tube of 997 pipes separating under load and causing major accidents. Ask at service time for a check of your cooling pipes to ensure they are clean and fit for purpose?
Braunton Engineering supply and fit the lower temperature (71 degree) thermostat to the Porsche 996, 997 and Boxster to reduce running temperature. This allows a cooling system to be controlled by a 71 degree thermostat over the standard 83 degree unit. Reduced running temperature has a number of benefits, most which have been openly talked about.
The key benefits of running your Porsche with a cooler running temperature, are a slightly cooler engine, will have higher volumetric efficiency - the cooler engine will allow more advanced ignition timing without detonation occurring which can increase power and fuel economy.
The lower temperature reduces the risk from hot spots within the engine, which in turn adds protection against internal faults (such as scored cylinder bores). Lower coolant temperature will allow the oil to run cooler too, another feature to protect an engine's health.
