well when i start my car from a cold start it makes a rattling noise coming from the head. then in few seconds it leaves. this started to hapen after my friend did the valve ajustment. we doubled checked the specks and it was good. but when we where doing cylender 3 the jam nut got striped and it wouldnt tighten the intake valves. so we took it off and placed a new jam nut in it. could it be the screw thing that you put the jam nut in that makes the noise?
