Vac pump destruction / mystery

[RJ Sledge]

Although my application was a Stocker, low to mid ten Ford small block, I had the same problem after about 5 or 6 passes. I had set my oil pickup clearance too short and it was starving my bearings. Set it to .400 and I never had any more problems. You can get it too close.
Sometimes its the little things you can take for granted.

Hope you figure it out.

An Accumulator can also help.

Thanks.......great point. Mine may be a little too close too @ .250ish. or less even
The only way to fix is to take a 2x4 and wack the pan bottom a little.
