Hi guys
Have my new engine built now and it's running in well be it gently. Recently I had a major oil leak as shown in another post when the oil cooler line popped off and covered everything (except the timing belt) in oil. I then used petrol when cold to clean this mess off to good effect.
Before this I had no noises but now I have a whirring noise that alternates with speed especially noticeable at low rpm. It doesn't make noise when cold. I have removed the aux belt and that made no difference. Oil level is ok and Pcv seems to be sucking in well. Doesn't change if clutch depressed.
My question really is can the timing belts make some noise when new? All my timing belt kit is new genuine Volvo other than the tensioner which I didn't change due to cost and it was extremely hard to compress back down! I tried very hard to get no petrol on the belt but got a small amount on the exhaust pulley which seems to be where most the noise is coming from. Can you effectively 'clean' the pulleys so they create a noise or is this a totally different noise?? Iv attached a link to the video.
Thanks guys
