Well, cost me about 3K in total for the L&N upgrade on my 2001 Boxster with 35K. The upgrade also included upgraded RMS and new clutch disk/bearing and some new cam seals (small leak). After buying the car about three months ago the lady that sold me mine had a catastrophic IMS failure on her newer model 2005 with only 23K miles..... I decided that the pain of looking for replacement engine (that could also fail) was not worth the worry and potential expense.

The mechanic said my bearing was good; and I only found small amounts of play if I really pushed hard from side to side or in and out, probably normal condition. I was unimpressed with how easily the seals can be popped off with a screwdriver and don't believe there was much grease in there after I did. All said the theory holds water with me that grease is leaking out in a hot environment the bearing was not designed for...although the inside of the bearing was lubricated it was more a mixture of some oil and residual grease (but I don't know about this particular grease viscosity)... I would be guessing, but could see the bearing failing at some point down the road...feel much better with ceramic balls, better race, and no seals in that each time I'm changing the oil it "REALLY" is doing some good! Now I will DRIVE is like it's REALLY stolen!!! :dance:
