Today I finished my LQ4 swap in my truck. The only changes from the 5.3 and the mods in my signature is the addition of an EPS 222/226 cam. However, all is not well. Upon starting I noticed a significant amount of oil leaking underneath. Upon looking I found oil to be coming from somewhere above the oil cooler block off. The oil cooler block off is dry and the oil pan gasket seems dry. It almost seems like it coming from the side bolt on the rear main. Any suggestions on what it could be? The engine has 0 miles on it.
