Yes, excessive oil pressure due to faulty lifters can contribute to blow-by in a new Chev engine build. High oil pressure may lead to increased crankcase pressure, which can force combustion gases past the piston rings, resulting in blow-by. Additionally, faulty lifters can affect valve timing and performance, further exacerbating the issue. It's important to address any oil pressure abnormalities to ensure proper engine function and longevity.
