Thought I had Piston Slap
My car made that terrible sound for about 2-3 min after cold startup, and about a minute after warm starts. I changed my cam this weekend from the stock 2002 ls1 cam to the 02- zo6 cam. The noise disappeared, not there at all. I know you should use 7.425" pushrods with this cam, but I was sent the wrong ones, so i used the stock 7.400 rods. So why do you think the noise went away? I also put in 918 springs. I'm thinking its that the lifters are now holding more oil to make up for the .025" diff in length. Should I put new lifters in. I don't think it was ever piston slap, maybe just bad lifters?

Some people on here are telling me it's piston slap, one of the mechanics I took it to said it sounds like a spun bearing.
