I recently did a cam swap on my 2007 c6 ls2. I now have have a noise a ticking/tapping after car reaches 195 degrees and stays for approximate 2 mins and then disappears. the noise never comes back unless the car sits for a few hours. no issues with performance but the noise comes on strong noise and is loud. This is not the typical valve train noise of a cammed ls2. please any suggestions I'd appreciate it.

new springs dual springs by pac.
new pushrods.
new water pump
new lifters.
car does have long tubes
etc the whole 9 yards.

lifters?
spring pressure?
cam profile?
oil pressure?

Welcome to the site. Describe some of the valvetrain components and I'm sure we can figure it out. This site has seen just about every F'd combo possible. Ha ha.

Did you change the oil pump? May have pinched the o-ring.

Is tough to say if we don't know what it sounds like it could be a fuel injector though a stethoscope can pin point the source about 5. at Harbor flee.
