<e30 M3> timing chain noise

|I am seeking advice on the title subject. About half the time I start my 90 M3
|after it's sat overnight, and particularly when it is nose up on an incline, I
|get a hellatious racket which dissappates after about 10 seconds. I am pretty
|sure it is the timing chain tensioner pumping up with oil pressure. How does
|it work? Is it easily replaceable without taking the "front" of the engine
|off? I see it's cylindrical body bolted up to the right side above the AC
|compressor.

Bob,

At the last Bay Area get together hosted by Richard B, I was about to show
Loren Luke my oscillating idle problem.  While starting my engine it
made a "hellatious racket" noise for about 3 seconds and disappears.  There
was about 5-6 people around my car and two said it was my timing chain
tensioner.
