Rattle on start up. Has new dr vanos already
I have a 2005 330 CI that has a rattle upon coldstart up. It is done it before the vinous change and after the Venice change and I'm wondering if I could have a timing chain tensioner starting to go out or the timing chain could be slapping the cover a little bit it only does it for a few seconds on start up but it worries me if something could be failing. the car only has 85,000 miles on it. It almost has a sound of that is when you change the oil on the car and it rattles for second till it builds pressure back up and I'm wondering what you all think that could possibly be thank you for any help
