Hello all,
I am experiencing a clacking noise from my 98 626 2.5L. I counted "clacks" while timing myself and figured out that the frequency is approximately 1/2 of the engine RPM in neutral. About 5 clacks per second when sitting at stop light. Wondering if any of you have experienced something like this and if so if you have any insights you are willing to share.
Thanks in advance! Will try to upload a video.
