A very unfortunate but very common Jaguar fault, a broken secondary timing chain. With less than 78,000 miles on the car, in this case it appears that the plastic timing chain tensioner guide had come loose. The loose tensioner guide was then caught between the chain and the sprocket, causing the chain failure.
A very unfortunate event, this Saab 9-3 turbo oil pan struck a rock and damaged the pan allowing the engine oil to leak out. Note the broken aluminum oil pan parts and material caught in the oil sump pickup. Metal particles may have entered the engine lubricating system.
Car had 50,000 miles, all services carried out and stamped in maintenance book, yet engine was ruined by oil sludge. Saab has been having an issue with this engine fault. We feel it is due to extended service intervals without the use of semi or full synthetic engine oil.
