Marks on oil valley cover LS2

[Carl cobra build]

Hi there

Just removed the oil valley cover on LS2 gen 3. I found erosion marks in the aluminium casting inside the DOD cover o'rings. See attached. is this normal? Should I change the valley cover?

Any advice is appreciated

Cheers

Casting marks ?

As long as it's intact and the o-rings seal I wouldnt worry

Looks the same as the one I've just taken off.

You are fine as long as you didn't have oil leak from the cover.
