Old timing chain on A22DHM (Z22D1) 2.2 CDTI engine on Opel Antara (same as Captiva, Orlando) after 120 000 kms. Chain was rattling violently after cold start, for second or two. It was really close to jumping and damaging the engine. Chain was stretched and the tensioner was done for. Fixed by replacing timing chain together with guides and tensioner. Job can be done in two days, because of the obnoxious oil filter housing placing and its mounting bolts while having to dismantle almost half of the engine. Absolutely doable, but you must replace all the gaskets and prime injectors correcly or you will end up with aired injectors and misfire or no start condition.
