Mine was burning some oil. It was blowing it out the exhaust. I'm going to look through everything since I have the engine out of the car.

Does anyone know how to tell the difference between a piston slap and a rod knock?

I think if u have the car running and pull off the spark plugs wire one by one if the sound changes that's piston slap when mine had rod knock before the rebuild it only knocked between 2500-3000 RPMs
