cm871 oil filter bypass valve update

[pearce trucking]

I don't know if this has already been mentioned here, but I wanted to note the TSB160017 from Cummins Quickserve dated March 20, 2017. I am going to update mine and will comment here as to the condition of the old one in my engine. By my reading, this suggests that the bypass valve may stick open somewhat, and could cause lower oil pressure. Obviously there are many reasons for low oil pressure, and it isn't something to be played with as it can destroy your engine if not diagnosed properly and quickly. However, this is a simple repair, and could save a lot of headaches if a damaged bypass valve is the only culprit. I am attaching a link. Let me know if it works.
