My engine has a small oil leak around the vicinity of the tandem oil pump (front of the engine) on the 1-3 cylinders side.
Looking at the PET, I found two large o’rings (95 x 2.5) that go between the oil pump and between the oil pump and the tandem pump, are these prone to leak?
Other leaks that have been already addressed: About a year or two, I had a leak on the same side (1-3 bank) that ended being the AOS, then recently another (large) leak that was caused by the accordion hose that connects the AOS with the breather valve (2-6 bank).
Thank you in advance for your comments!
