The filter doesn't have to clog completely! The factory bypass is horrid and will open fully at start up if the filter is only 30% blocked and thats with 0 weight oil.
Unlike other engines that have a bypass that sends bypassed oil back to the sump, the M96 doesn't do this as it simply pushes a plunger down and allows the bypass oil (material laden) to go right through the center of the filter. This is how bypass oil delivers death (if material laden) to all other internally lubricated components of the M96 even if the filter is NOT clogged, as at start up the filter will always bypass a portion of the oil. When that bypass spring is exposed to excess temperature the spring loses tension and therefore open sooner and bypasses even more oil.
If you have enough debris in the filter to be noted with a naked eye, its enough to pop the bypass. People don't know, what they don't know about this system. It takes seeing failures everyday to understand the dynamics behind it.
So, the filter does NOT have to be completely "clogged" to increase bypass oil. I have redesigned the entire primary oil system, its the next product that you'll see released and it solves this problem.
