High compression + cold engine can also = knock
Lack of oil getting to all the important places can also sound like knock...


My truck is a great example, first 1-2 seconds of start up when it's cold out = rattling engine, especially the valvetrain - sounds similar to cylinder knock. Once the oil hits it with pressure it goes away. Not a whole lot I can do about it either...just hope there's enough residual oil stuck to the parts...
Anyone noticing a noise when the clutch is pushed in.I can feel what seems to be a little noise like the throwout bearing when the clutch pedal is pushed in and it has a little vibration through the pedal.I had someone hold it in while i listened under the hood but could not hear anything but you can feel it through the pedal.My car has almost 11,000 miles on it and was wondering if anyone else feels this before i take it in?
