    Question Valvetrain question

    Hey, I had a new cam, pushrods, rocker arms, and lifters put in. When I crank the car up it sounds really good, then after about 3 or 4 minutes, I have a clacking noise that comes from the valvetrain. I can take her out, run around for 10 minutes, come back home, and its gone. I have changed over to Pennzoil Platinum 10-W30 just after the install. I thought maybe it was a pushrod too long, but that doesnt explain it going away. Any help would be greatly appreciated. I really want to see what this car can do, but scared to death Im gonna blow it up!!

    To be honest I'm not really sure. I had a shop in Carolina install everything, and the lifters were part of the cam package they offered. You think it could be linked to that? I am waiting for the shop to contact me back, but I am trying to gather as much info as I can before hand.
