Feeler gauges? I don't need 'em. I just wiggle things around and measure the clearances by how much the move in my hand.
I have a set somewhere... I think...
The noise is definitely coming from something attached to the timing belt. I ran it in my driveway with only the t belt and nothing else connected. I was 99.9% sure it was the plate behind the crank pulley, as I could see it rubbing against the oil pump for a short while, but I took it off and flattened the thing out and put it back together. the noise went away for a couple weeks and is back now. WTF? grrr
