I guess my concern would be ,Id have thought alloy shavings could float on oil, then perhaps the big end/crank could dip the oil and pick this up, probly overthinking things, but ive always removed sumps on other turbo installs, to fit the oil return.

Anyway, John i don't wan't to start spamming up a exellent build thread, so if its still all working then sweet, lets leave it at that.
