M42 knocking sound help
« on: June 05, 2013, 01:58:01 PM »
Hello,

My engine started making a very loud knocking sound.
It's a E36 M42. Hidraulic tensioner is new. i'm guessing bent valve, hydraulic lifter failure or maybe something worse..tell me what you think.
you can ear the sound here and here

How did you install the tensioner?  It wasn't full of oil or fully extended, was it?
