406 sbc oil pump noises - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hiya guys,

After replacing the oil pan, intake, and timing cover gaskets on my dad's built 406, we're getting some scary clicking/ rattling noises from (what we assume to be) the oil pump when we go to prime it. It is making good pressure but the noise is pretty concerning.

Here's a link to a video I recorded of the sound. https://youtu.be/wCaWiZHt0WE

We're going to pull the pan tomorrow and take a look to see if the pump is touching, but when this engine was in my dad's Nova we never noticed this sound.

What do you guys think?
