I see some people here referring to some things as absolutes. Knowing a bit about stats, and having an advanced math degree, I seriously doubt that MB would use the word "always" or "never" or "must". Running jugs hot is a known factor for early failure modes. I would be surprised if his statements on things like this are framed in such discreet language. I'm pretty certain from my experience with his delivery, he'll explain why some factor will cause early failure, and also how to evaluate it for avoidance of catastrophic failure.
One things I use regularly is his philosophy of the engine 'talking' to the pilot. I knew I was having a top end issue when my oil consumption increased by 30% and eventually found a scored cyl which needed to come off. And - I also doubt he would 'never remove a jug'. Jugs are put on a crankcase with bolts, studs, nuts, washers, meaning they are intended to come off for repair/replacement. However - the common maint philosophy says that in 90% of cases the jug comes off for repair/replacement, notwithstanding the issue may clear up on its own, or it may be resolved with other means, or it may be a condition that the pilot can live with if it doesn't affect safety of flight. As an example, sometimes studs leak oil from the cyl base. Sure - the engine can come off the plane, be stripped down to component parts, replace or reset the stud in question, use the proper type of sealant, or O-ring as defined, and reassemble and install the engine back on the plane. Or - it might be a lot better to use some hi temp RTV, a viton O-ring and run it like it was stripped and done right.
What potential maint faults can be introduced during a teardown, repair, and assembly? What potential material defects can be introduced during the teardown and assembly? Suppose it's an engine with a cyl base O-ring or gasket and it gets pinched/crushed on assembly? Well, pull it, teardown, fix it, assemble it and put it back on the plane.
These are the types of things that I think Mike contributes. As far as any pilot casting aspersions about HIS ego and/or personal style, well - pot meet mister kettle. I tend to rub people the wrong way sometimes, including here and here's a kind of secret. It's a feature, not a bug.
