    2007 Cayman S
  1. The car is alive again. Fired last Friday 3/20 and was racing Saturday AM at WSIR. The diagnosis was a failed #1 rod bearing, resulting in a broken craddle, two broken cases, a broken, rod, a couple of bad pistons, etc. We purchased a used Cayman engine (from a 3.8 swap) with just over 2000 miles on it (Brad, you apparently know this engine) to use as a rebuild donor. Several chnages to improve oiling and reliability including a modified crank and installation of Carrillo rods: Cheers,
  2. Only X51 engines. thx Loren, what about the 2005 and beyond 3.6 and 3.8 engines... did they have any type of oiling implements that were not present in the 2002-2004 3.6 engines? Bump to Loren. I am also curious as to 1) are there changes to the M97 that make this modification unnecessary and 2) if not, can this kit be installed on the M97? Cheers, From the 997 Technik book... "The 911 Carrera engine employs a mechanical vacuum pump instead of a conventional sucking jet pump to provide the vacuum for the brake booster. This pump is driven in tandem configuration togeth

  4. Brad, Thank you for the photos and information. Yes, I know the engine and was there when it failed. According to Quinn there were significant high-range overrevs, so many that he doubts the accuracy. I assume it was quinn that called you from the track. The car is at Vision and the engine was set to be torn down yesterday. There was bearing material in the pan and oil filter, but I do not know any more beyond that. I assume if you contact Dwain he will share his findings with you, and vice versa. I hope to visit the shop on Monday PM. Cheers,
  5. The engine in my 2007 Cayman S failed this past weekend while on track. It lost power, began to vibrate, displayed the CEL and low oil pressure warnings, and began to clank. The engine has 46K miles on it, including 5000+ on the track. While the engine is not yet completely apart (should happen today) the initial inspection showed connecting rod bearing material in the oil pan. Other parts may have failed as well, but this is what we know for now. Our path forward is not yet clear. We can install an OEM remanufactured engine, buy a local used engine, our more than likely rebuild the existi
  6. Good explanation, I am more and more convinced that the idle ticking on the right bank isn't a bad tapped but something related to other components or a lubrication problem (clogged duct?). However those parts doesn't belong to the 3.4 (996) engine, they are part of the improved variocam (plus) of the 3.6 version, so my problem actually should be a different one :( cheers Teo Teo, The problem could be the same. The 3.4 in the Cayman has the variocam plus head. It is different from the 3.4 in the 996. Cheers,
  7. Adding cross post for the record: My 2007 Cayman S (M97.20 engine) developed the similar/same "tick" that was intially random and finally became constant. Over the next week or so the car developed several other noises that sounded like the exhaust/heat shield rattling. After some investigation the transmission was removed and the DM flywheel was found to have failied (the car is raced). Our hope, therefore, was that this failure was the root of all evil. Unfortunately it was not, and when the car was back on the ground all of the noises were still present. Other symptoms included occasion

  9. Yes, I understand that the two chamber AOS will fit on the 986 Boxster. In fact, Porsche has apparently had a TSB in place (see attached .pdf) on this for quite some time (at least in the UK). Vision Motorsports in Laguna Hills, CA should be able to do the installation as they did the install on my Cayman S (this was a PITA). The part can be ordered directly from Suncoast Porsche (or any dealer) and does not need to be ordered through a race shop. Cheers, Porsche_Oil_Ingestion_Fix_1_.pdf
