ok well we changed the plug and ran it and pulled the plug and the gap was still good. the weird thing is that the noise comes and goes, it sounds like rod knock but then it goes away for a while and comes back, and the intensity of the noise changes also. and now there is a ringing noise coming from the turbo, WTF? its just so random and happened so quick we are trying to think outside the box a little, that or we dont want to come to terms with the fact that we have to rebuild the motor. my buddy that put the plugs in the first time said that they came with the motor and he didnt even check the gapping.
