  1. Don't really understand the negative reaction to my post. Bearings aren't magic: they have an inner and outer diameter. LN uses an industry standard bearing which can be sourced from hundreds of places for a variety of prices. I am replacing the IMS sealed ball bearing with an unsealed cylindrical bearing of the same dimensions and lubricating the affair with an oil feed taken from a spin-on oil filter adapter. I've taken a bearing end cap ($50 used) and drilled and tapped it to take a threaded oil line, then I'll run that line through a small hole (or cut out) in the bell housing to the oil filter. I've been building RR and Jag engines for decades and solving similar oil starvation and vapor recirculation problems with much more exotic fixes than this. I just think the purveyors of the various kits out there for the Porsche engine are taking the mickey out of owners purely because of a problem that, statistically, happens to 10% of the cars not modified. Don't forget: a 10% failure rate is a 90% success rate. In comparison, 100% of the early Honda Civic engines that did not have a timing belt change at 11,000 miles intervals suffered severe engine damage yet the replacement kit cost little more than the original equipment part. As an aside: I have heard from more than one source that simply removing the seal on the IMS bearing will lubricate it sufficiently if one uses an additive (STP, Lucas or similar).
  2. I sourced the same same bearing from the UK for $25.00
  3. Oil change shouldn’t be necessary unless you stored the car under water. Have you tried an additive? could be the IMS
