Can a Porsche Boxster brake system be bled?
The basic Boxster brake system with anti-lock brakes (ABS 5.3 and 5.7 without PSM) can be bled using traditional methods. For cars with traction control or Porsche Stability Management (PSM), you need to use the Porsche System Tester 2 (PST2) in order to activate the valves in the hydraulic unit during the bleeding process.
What causes a Porsche Boxster engine to leak?
On the early cars, Porsche also used a center bolt to secure the IMS bearing that was too weak and sometimes snapped. If this bolt breaks, then the intermediate shaft begins to float around in the bottom of the engine, and you can soon experience catastrophic engine failure. This area is also highly prone to leaks.
How does pressure bleed work on a Boxster?
Pressure bleeding uses a reservoir of brake fluid that has a positive air pressure force placed on the opposite side of the fluid, which forces it into the brake system. Vacuum bleeding is where you fill the reservoir, and then apply a vacuum at the bleeder nipple to pull fluid through the system.
What kind of engine does a Boxster 2.5 have?
The problem affects mostly the 2.5 and Carrera 3.4 engines: the 3.2 Boxster S engine appears to be unaffected because it has thicker cylinder walls than the 3.4 engine. When this failure happens, you will see oil and coolant begin to mix together, or a slight unexplained coolant loss.
