09 LS3 oil pressure issues
#12
After reading more about the LS3 I`m starting to think you might (maybe) have a cam bearing that has walked out. If there was a bad o ring on the oil pump there would be air in the oil that makes the lifters tap, and you said no tap being heard. I`m starting to think you have an internal leak. My thoughts on this. I could be wrong. taking off the oil pan to verify bad cam bearing. You can run this by your guy and get his thoughts.
