Hi tintin2112,

Thank you for the donation.

I am not sure if I am reading your question correctly so correct me if I am wrong.

The 2 pipe joints are water passages and there should not be any oil leaking from them.

If oil is leaking, either the O ring ( red in your picture )is not seated correctly, the internal bolt is not correctly torqued or the oil filter is the cause.

If oil is leaking from water pump, coolant would be contaminated with oil. Is that happening?
