I have never seen a timing chain FAILURE on this engine. However have seen several with over 200,000 miles that did need a new chain, as the cam timing was more than 4 degrees off.
Head gasket leakage is VERY common on this engine!!
ONLY "ELRING" brand headgaskets ARE modified to hold the oil pressure from causing leaks.
