oil pump leak?

[Gilles]

Does the tandem oil pumps tend to leak oil through the o’rings..?

Perhaps the small leak on the front of the 1-3 cylinder bank comes from the tandem pump..

Post a pic of leak. I have never had any leaks from the oil pump but a picture might help anyone else viewing this thread in the future (once there are answers).

I say no, the scavenger pump is a tight machined surface fit in the head with a large O-ring.
