Yes. That's what I thought. There was air bubbling out at a single point as though someone was blowing with a straw from the other side. Next question- what is that fitting that's shown in your picture? That's the redrive return Rusty (decided to wait for UPS to finish putting my engine together) I didn't know UPS offered that service. :) John, is the oil drain hole partially blocked by the plate? Could some turbo parts have slid down the hose to get trapped? Turbo parts? What? you mean bits of turbo? I hope not. I was thinking about hot oil landing on the mount plate from the redrive and turbo returns, then running along the plate and out of the join rather than finding its way back down to the sump. Doesn't explain the bubbling air though. I could try the fluorescent thing tomorrow, but as Ernest said - it's pretty obvious that I have a hole between the engine and the mount plate.
