It's been a long time since this happened to me, but I have'nt run Purolater filters for years. Started a fresh engine build (SB Chrysler with all the goodies ) and broke in the motor with Purolator filter because they were on sale two for one. Ran the motor for 20 minutes to break in the cam in my driveway, went to change the oil and it had started to suck the filtration media into the engine. The other filter went into the trash. I've run nothing but Fram or Wix since that day. Just my 2 cents.
