I bought a GM performance 350 crate engine for my truck. I put 'er in, hooked everything up and pre-lubed the engine for about 5 minutes to make sure everything was good and oiled.
I fired it up and I hear KNOCK KNOCK KNOCK...WTH!? So, I find out my passenger side lifters aren't getting any oil pumped through them. Yet, the drivers side is getting oil as it should; WHY?!
