2001 A6 4.2 - Timing chain tensioner cracked and chain jumped
2001 Audi A6 4.2 (72k miles) had the timing chain jump after the plastic tensioner cracked, resulting in one half of the engine shutting down.
Mechanic feels that repairing the tensioner may only fix one part of the issue, as he's not sure what other damage may have occurred in the engine. (Plastic from the tensioner was found in the oil pan). Doesn't think that it's worth the money to replace the engine with a rebuilt one. Any thoughts?
