Timing Chain issue immediately suggests this car is a 4.4 with an M62TU V8 engine. They are know to suffer eventual chain guide failure due to the unfortunate fact that the timing chain guides are plastic and eventually crumble / fail. It "can" be a DIY job depending on the level of skill. It involves dismantling most of the top and front end of the engine and requires the engine to be properly timed / set upon completion. You would require some special tools like the VANOS timing tools to do the job properly and safely.
