NOISE FROM THE ENGINE

1997 BMW 318

Noises problem
1997 BMW 318 4 cyl Two Wheel Drive Manual 110000 miles

I have a BMW 318ti and the car's revs starts dropping when the engine heats up or I stop at the lights ie when idle. There is a loud whistling noise as well that comes from the engine and the whole thing shakes. There was a cat converter that rattled alot and I changed it but the is still happening. Any help

Replace part number 16 in the link I am sending you, it is the crank case vent valve, it is a high failure item, as are the hoses.
