We had a recall a few years ago to reseal and retorque a timing chain tensioner. 4 cyl twin turbo diesel, timing components on the back of the motor.
The tensioner is on the right rear of the engine, above and behind both turbochargers. The catalyst/DPF is behind and below. You would have to move some serious oil to reach either one.
Here's the explanation from the recall, fire is on there, but down the list.
"Over time, this might lead to loosening of the chain tensioner, as well as an ineffective sealing ring seal for engine oil. As a consequence, leakage of engine oil onto the road might pose a threat to traffic. Should the oil leakage reach a certain amount the engine might stall. Oil leakage in the presence of an ignition source could also increase the risk of a potential fire. "
