V50 – loud pipe from engine compartment (not oil trap, not LiMa)

Hello Elcher! I’ve been having the following problem for a few months:http://sdrv.ms/Teuyy7 (If Firefox complains about Silverlight trying with Chrome) It’s not the oil trap (crankshaft housing) that was done last year. The LiMa was changed only 2 weeks ago, it can’t be. The timing belt was also made in the same train, including all belts, rollers, tensioners, pumps etc. Everything original at Volvo just. Since the fun last cost me a lot of money ha t, and the Volvo-Monteur meant this is the Lima that is working now, because the battery may not be fully charged, it stirs me up more and more every day… Can you guess from a distance what that could be?? Thank you for all relevant notes Edit: Oh yes, it’s a V50 T5 BJ 2005
