Jim,
You'll probably getting the same results with your lube.. squeaks but not so much rattles.
But I have some other rattles too, my hood touches the top front corner of the motor which adds to some vibration rattles. My front hood hinges are riveted to the inside of hood, moving the hinge to the bottom/outside will raise my hood the thickness of the fiberglass (approx. 1/4in) and hopefully solve that. I'm hoping the joints & hood are 80-90 percent of my rattles. You can hear everything with these cars, disc braking, motor noises and with speed the wind takes over.
Guess it's not the noises you know, it's the ones you don't.
