This filter only had just over 1200 miles on it. My engine started making a ticking/rattle sound upon startup so I replaced it with a MC FL-400S. So far so good.
I doubt it was the PureOne, and by the looks of the guts there was nothing going on with it to cause a tick. Did you inspect the ADBV carefully to see if it wasn't sealing well on the base plate or leaking somehow?
I thought you also got start-up ticks in the past with the MC filter too (?). If you are getting ticks with more than one filter, then it's probably something else going on.
Before cutting it open I did notice the ADBV was kind of offset to one side of the holes. I didn't think it was that bad so I didn't take any pics.
At about 88K miles I did an OCI with MS5K and a FL-400S filter. I was getting a tick/rattle about every 4th startup. Prior to that I had only used MC oil with MC filters.
I did a OCI with Castrol SynBlend and a MC filter and all was good. Every FL-400S I have used since then has never given me any problems, or even before that 1 time.
Maybe it's the oil causing the noise? Time will tell.
