depends on the temperature, so the noise is the tensioner? thats just the screw thing with the cylinder that screws in just below the head? i didn't know that could go bad, looked like a part that wouldn't wear... maybe i should replace it, iv got 240,000 km or like 149,000 Miles. im guessing i should do the tensioner?

Choosing oil weight also has to do with the internal tolerances the motor is built to. Too thin of an oil in a loose engine is a bad thing. On M42 you can get away with 10-40, but 20-50 woudnt hurt as long as you're not it a really cold climate.Adam Fogg- '88 M3
