Could be bearings clearance or it could be the oil pump. Ken's thoughts were that pumps do go wear out.
I already installed an indigo remote oil filter plus their oil cooler in an attempt to stave off the rebuild. I'm also using the Indigo thermostat, so I have nice toasty and consistent 180F water temp with their electric FWC.
So I'm heading down the rebuild path on the spare motor... and trying learn as much as possible about 'best practices' from the forum. I have all the MMI tech tips archived, but looking for do's & don't from our very knowledgeable members.
... and I will make positive to install all three internal oil plugs.
