So I have a 54reg 3.8S with 51,000 miles which I bought 2 years ago. I love the car which is my daily driver and has done 3 trackdays and the Northcoast 500 route in Scotland. I have a 911uk thread here http://www.911uk.com/viewtopic.php?t=114307&highlight= . Soon after I bought it at 32k miles, light scoring was found in cylinders 5 and 6..... so I knew at some point a rebuild would be on the cards, but I was hoping this would be a few more years away. 2 years later on and 20000 miles driving since I bought it and the scoring has hardly changed and my oil consumption is low, so thought I had plenty of time before a rebuild would be needed :roll: (I have an LTT fitted, third radiator and change the oil every 5000 miles.)
My car being a 2005 model has the smaller IMS bearing fitted to it. We all know that these can fail and I was planning to change it when a new clutch was due, as the failure rate is still pretty low. Unfortunately my bearing decided not to wait for a clutch change and yesterday this happened :frustrated:
IMS Bearing has eaten itself, IM Shaft is knackered and swarf in engine, (also missing a few ball bearings). Engine rebuild required :sad:
I had always accepted that I would need to get a rebuild in the future, (with Hartech liners etc) but as bore scoring is a slow death I thought I had plenty of time to plan/save etc. Catastrophic IMS bearing failure however is instant engine death and brought the rebuild much sooner that I would have liked and definitely not come at the best time....
If you still have a smaller IMS bearing fitted to your car and have done less than 80,000 miles I strongly suggest you get it replaced ASAP rather than just waiting till clutch change time.
