Timing Tensioner problems of the 2004 Saturn VUE

The vehicle was started in the morning to move it a short distance. Upon attempting to start the vehicle later in the morning, it was not possible to start the engine. It attempted to turn over and made some muffled noises and then would only crank with no sign of firing. Upon researching the issue it was determined that a timing failure was likely. Once the timing cover was opened it was discovered that the plastic chain guide had broken into four pieces. Additional damage included a partially sheared oiler nozzle, stripped bolt holes for both lower and upper attachment points for the plastic chain guide, bent intake valves on every cylinder and dings on the intake side of the pistons. At the time of the incident the vehicle was also fitted with the old style tensioner (flat bolt head style) and the original timing chain oiler. The timing chain was evaluated against a new chain and was determined to have stretched the length of one link. The head was pulled and sent for repair where the valve damage was exposed; in addition three valve guides were cracked and there was a significant abraded area on one of the cam races. The head was determined to be a loss and a new head was purchased. There appears to be minor damage to the piston tops, and they are currently being evaluated. So far this incident has cost approximately $1000 in parts and diy labor. It has caused me to miss over two weeks of work ($600-$800) as an independent contractor who relies on this vehicle. Given the extent of similar experiences involving the ecotec 2. 2 l engine this vehicle is equipped with, it is surprising that there has not been a recall.
