I have an 04 K12GT of which the cap bolts holding the bearing cap on the bottom of the connecting rod to the crankshaft on the number one cylinder broke, causing the rod to crash through the top of the block. I'm wondering if this is anything anyone has experienced? It appears the bolts themselves snapped right along the seam from con rod to cap. 78,000 miles. I wasn't even "blowing out the carbon" at the time. Have there been any recalls? Service bulletins?
