Well I've searched and there's been plenty of topic about clicking engines at higher rpms.. but the issue I am having is very specific.. I used to own an acura integra and it endedup with a slightly bent valve, and so evermore it had a ticking coming from the engine.
I am getting this precise sound from my '95 M3, but only when it's idling. My car idles around 800rpm and normally after it idles for about 2-3 minutes it begins ticking. A gentle rev will make the ticking go faster, so it's definitly engine related. A rev to about 3k stops the ticking, but it will usually pick back up after about 30 seconds.
My thoughs on this issue is that it's an oil problem.. the engine rev kicks up the oil and the car is fine until it drains back down, wheras it starts ticking again.
Anyone had this same issue?
