Probably one of the nose gear cogs is snaggle toothed. The pulley rotates a quarter turn in either direction before the gear engages. When idling the supercharger sounded like large chunks of ice knocking around in a blender. Much of the lobe coating was missing also.
WOW Keith you really do great work! Why cant someone like you be located in the NY area!?!? I've been having problems with my car for a while now and was recommended a BMW mechanic that does work on the side and so I dropped it off to him without hesitation and the end result was less than I was expecting. $1500 and the car is still displaying the same symptoms it came in with!!! GRRR Thank you for sharing so much with us! Like others have said you get to see things most of us hope we never have to see but none the less invaluable information to read about and be cautioned towards. Thanks, Steve
Hey Steve.... Consider a little vacation time down in Pipe Creek, Texas. And while you are sunning yourself, Keith can look over your MINI. Just something to think about....
Not 100% sure but there is a chance that I might move to Austin, TX at the beginning of next year. First thing I did was check out how far a drive to Keith's shop it is from Austin.
[SARCASM FONT]You mean those little balls aren't supposed to be loose?[/SARCASM FONT] Yipes man. Hopfully that got remedied before any other major damage occured.
Yes, thankfully. The stock flywheel, clutch disc, and pressure plate are in great shape. Except, of course, for the fingers the release bearing was pushing against. They are sitting on a shelf in the garage in the OSGiken box.
I installed an AST 5100 kit in an R56 today, the Vorshlag camber plate was originally installed on an R53. Using the original bearing and spring hat, I attached a new Vorshlag R56 base plate. The new bases are made of aluminum, and anodized an attractive shade of red; they weigh much less than the former steel stock. They also have reference lines the old plates lacked.
Today's Job #8 The project started as a turbo replacement on a JCW R56; the second replacement BTW. The first issue I came across was a loose O2 sensor; evidence of exhaust blow-by on one side, and a very white sensor. After the heat shield came off, a crack in the downpipe was uncovered. With the turbo removed, a crack in the exhaust manifold could be seen.
An aggressive aftermarket tune was on for almost a year; recently detuned, and AP stage 1 loaded a few weeks ago.
It's hard to tell for sure, high EGT is apparent, but as for the exhaust manifold the crack could have been the result of a casting fault. The support brackets were loose on the downpipe, and the turbo support was tweaked; could have been vibration stress that caused the downpipe crack. A tuning professional who looked at the first map used the word "aggressive" to describe what he saw, and later assessed "...it seems like it has the possibility of being too much for track or street..." when I asked about engine safety concerns, so indeed the stock tune could possibly have helped avoid component failure. I don't know the answer for certain. The first core is gone, so it can't be inspected. The owner is keeping the second core and another local R56 JCW owner with a failed turbo kept his core. When these are rebuilt, we'll have a better idea. One thing out of the ordinary preceding the recent failure was excessive oil in the output side.
