I have had a ticking sound since I rebuilt my engine about a year and a half ago. I have not driven very much because of the sound. I finally pulled the heads, thinking that there was vavle to piston interference. Come to find out, there is about .025" of piston to bore clearence. I checked this with a pin gauge and the piston pressed to one side of the cylinder. Is that the correct way to do it? The machine shop is closed for the weekend, so I cannot call them. When they machined it they insisted that they needed the pistons, because they machine the block to the pistons. Obviously that did not happen. But because they said they machined the block to the pistons I did not check that when I originally assembled it. Do you think the machine shop has some responsibility for the probglem or is it just my fault for not checking? I think now I need to re-hone my cylinders and get new pistons. Should I have to pay for all of it?

Thanks,
Kyle
