2.0t tickover

[decks]

i have a 2.0 turbo vectra and was listening to the engine tickover, and there is a noticeable ticking from the engine, now i know these are chain driven, but its not a rattle just a heavy ticking noise, this could be normal i dont know, just wondering should these engings tick over smooth with not much noise. i have not mapped the engine , engine is standard.

Mine is exactly the same, sounds like a diesel! I thought it was a loose plug at first. been like it for 2 years now on n off never found out what it was

Try an oil change, using very good quality oil - you may find the noise disappears. Also, the alternator belt tensioner can start to make a noise when it gets old.
