Alfa156Melb 9 Report post Posted December 18, 2012 I have a squeak in my engine, it sounds to me like it's probably a belt, but I'm not entirely sure. The sound goes away after the engine's warmed up and the cam belts have been changed 20,000km's ago... I am planning on taking it in to the mechanic, but as the noise is completely gone after the engines' warm, outside of leaving it with him overnight, I'm not sure he'd be able to shed much light on it.. Here's a youtube, you can just hear it in the background.. the frequency changes with revs and then fades away as the engine warms up. Any ideas?

K9d 108 Report post Posted December 18, 2012 I have a similar situation on my 156, mine is a squeaky bottom pulley for the aux belt. I spray it with Duck Oil and its stays quiet for a week then. Quote Share this post Link to post Share on other sites
Alfa156Melb 9 Report post Posted December 18, 2012 Well it turned out to be the cam belt, we think probably the tensioner.. So it's getting a new cam belt kit fitted tonight... Because i don't have an engine tray, and I'm also missing a side engine cover too (Driver side) all the dirt and muck makes its way in... it might have lasted, it might not have, i'd rather play it safe.. especially given I've already killed one engine because i was lazy with the cam belt..

K9d 108 Report post Posted December 18, 2012 I'm missing a liner in the wheel arch which allows all the muck to get thrown on my pulley. Quote Share this post Link to post Share on other sites

Smaky 73 Report post Posted December 18, 2012 Sounds like a dry power steering pump, check the level in there. Other probables include the aux tensioner and idler or maybe the release bearing, but really need the camera to go all round the engine bay to pinpoint it.

Alfa156Melb 9 Report post Posted December 19, 2012 It was the cam belt tensioner.. Got a new kit fitted with water pump to be safe and sound.. Its so quiet u can hear a mouse snore. Engine is miles smoother too, idles perfectly.. The timing mustn't have been bang on before. Sent from my iPhone using Tapatalk Quote Share this post Link to post Share on other sites
