50,000 miles. In shop because of security system malfunction and an oil change. Mechanic informed me that an ims bearing is throwing off brass flakes which I could see in the oil filter. This problem will eventually cause the engine to fail. Evidently it cannot be repaired. The only solution is to put in a new engine. The3 2001 Porsche is known for this engine problem and should be addressed by the pna. According to my mechanic the engine is flawed in its designed and never should have been allowed in the first place. There should be a recall for this car.

The Porsche 996 GT3 motors have a known issue among owners. The coolant fittings are epoxied to the engine and under high temperature/pressure usage, they are known to come lose and/or detach completely causing coolant spill all over the tires and road and deprive the engine from coolant. This causes the car the lose control and is dangerous for any cars behind the car this happened to. My car has this engine and as preventative safely maintenance, I have paid an independent shop knowledgeable about this issue to weld my fittings.
