E60 M5 Engine rattle noise
Hello guys, this is my first post, I'm Daniel, from Brazil, I have a mechanic shop here and one of my clients brought an M5 with rattling noise.
After some research I decided to remove both chain tensioners for inspection and both seemed to have low oil pressure on them, the right side one had a little more pressure (and engine rattled more on left side).
I ordered new tensioners and my real question here is. can I just screw them on and star the engine? or do I need to turn engine mannualy, check timing or something else.
Learned a lot about these cars here but couldn't find any info on this.
Thanks a lot
