Not the best of engines from Vauxhall.Possible coil cassette faulty or more likely a worn timing chain .The latter would make this a non -economic repair.

This engine is well known for timing chain problems. It's possible the chain has stretched and knocked the timing out which explains the rough running and lack of power. Stop using it, there's a strong possibility it'll fail completely if this is what is causing the noise. It's highly likely and it'll kill the engine if it snaps. It was never a good engine.

If anyone owns or intend on buying any GM product with this engine it's vital that it has fresh good quality oil every year. If there's no proof of it or you've neglected it, it will go wrong. This one has lasted longer than most though so someone must have been caring for it at some point.
