For the Porsche owner, the phrases \u2018IMS bearing failure\u2019 and \u2018spalling\u2019 are the cue for eye-rolling, hand-wringing, and \u2018replacement cost\u2019 are not far behind. A raid on the ISA or other form of nest egg feels inevitable. But it\u2019s not inevitable.<\/strong><\/em><\/p>\n

Could I be affected by IMS bearing failure?<\/strong><\/h2>\n

There\u2019s no getting away from it \u2013 IMS bearing failure isn\u2019t good news. Looking beyond simple replacement cost, the collateral damage can be immense. But if you know what you\u2019re looking for, and act in time, a failing Porsche IMS bearing failure isn\u2019t a dealbreaker either. Luckily, your friends at Design 911 can help. So, here\u2019s the inside track on Porsche IMS bearing replacement.<\/p>\n

If you don\u2019t drive a 986 Boxster, a 987 Cayman, a 996 (but not the GT or Turbo), a 997 3.6ltr packing an earlier M96\/05, then you\u2019re free to go. If you\u2019re not sure, read on, or ask an expert<\/a>.<\/p>\n

Let\u2019s talk engines.<\/strong><\/h2>\n

Specifically, the M96. It\u2019s the powerplant driving every 996 Carrera model and the basic Boxster. This mill replaced the legendary air-cooled, two-valve, single-overhead-camshaft flat-six synonymous with the 911.<\/p>\n

First introduced in 1996, the first incarnation of the M96 was the 2.5L flat 6. A year later, it took a bow in the 911 as a 3.4L flat 6, and a further displacement increased the capacity to 3.6L. Water-cooled, it was therefore not instantly popular with the Porsche purists, who prefer a naturally aspirated mill.<\/p>\n

Like Dylan going electric<\/a>, it annoyed some but for in-house engineers, the M96 and latter M97 were the strategic change up that would power the next gen Porsche 996, the 911, and the 997. It was more powerful, generating around 296 BHP, cheaper to make and easier to maintain.<\/p>\n

No engine design is perfect, especially the first time around, and owners reported rear main seal leaks and cylinder cracking in early M96s. But that\u2019s another story. In this article, we\u2019ll look at Porsche IMS bearing replacement.<\/p>\n

What is the IMS and what does it do?<\/strong><\/p>\n
