K&N HP3001 (similar in size to FL1A/PH8A). Lifter tick? None if driven a couple times a week. There's about ~6 feet of -8AN SS hose, a 24 row oil cooler and that filter before returning to the main oil galley and THEN the cylinder head. There's something to be said for a primed oiling system that doesn't loose it's prime, for whatever reason.

...of course, like most DSM's, it's a (*&^(*#%@#$ garage queen!

i found this interesting

Russell,
I obtained great satisfaction from reading your oil filter survey.

I worked for two years as the oil-filter production line engineer in
an Allied-Signal FRAM facility and I can confirm every bad thing you
have said about FRAM automotive filters. That's from the horse's
mouth, as it were.

I'm also a quality engineer and can confirm that FRAM applies no
quality control whatsoever to any of the characteristics for which we
buy oil filters. I frequently saw filter designs which were barely
capable of meeting J806. Many of FRAM's designs will block and go to
bypass after trying to filter very little contamination. There were
often leakage paths at the paper end discs when these were not
properly centered on the elements. Some designs had the pleats so
tightly packed against the center tube that they would block off in no
time. I had discovered that the FRAM HP1 that I had been buying for
about $20 Cdn was EXACTLY the same as a PH8 inside - the only
difference being a heavier can - no advantages in flow capacity. The
paper filtration media was of apparently poor quality and the process
of curing the paper resin was very inconsistent - elements would range
from visibly burnt to white. FRAM's marketers admitted that there was
just about no way the public could ever prove that an oil filter
contributed, or did not prevent, engine damage. The only thing FRAM
tested for was can burst strength. Another problem that they have from
time to time is in threading the filter base - often there are strands
of metal left behind on a poorly formed thread.

I have not used a FRAM filter since I started working there. Their
claims are entirely and completely marketing bullshit.

If people really want to protect their engines, a good air filter is
vital (which excludes FRAM from that list as well) and a combination
of one depth and one full-flow hydraulic filter, together in parallel,
will do the job of filtration to perfection.

Thanks for doing a great job in trying to get the truth out! You can
quote me anytime.
