147 Engine Whine
HI there, I've read through many of the forum posts regarding various whines, but couldn't spot my particular one - so perhaps you can advise.
When my wifes [53 plate] 147 is started, especially from cold, there is a strange pulsed whine coming from the engine. The pulsing whine is clearly a tied to one of the rotating components; its certainly much slower than crankshaft speed. Could it be the aux belt or tensioner? If it was the waterpump it would pulse at quite a high frequency; this is only about 2-3 times a second.
The top end was overhauled by the dealer last year fater the cambelt snapped at 31000 miles.
Thanks in anticipation.
