It's 800 miles early, but the oil p dropped and started that horrible clacking noise again. It's supposed to be nice Sat and Sun, so I'll do an early oil change. Results posted when I do. Note: changing the oil does not always result in stopping the clacking...

Most filters have an anti-drainback valve (or if not, then there is usually one elsewhere in the system). On Ford modular V8, if you get a filter with a marginal anti-drain back vlave, then you are likely to get chain rattle if the engine sets over an extended period of time. The cam drive chains are tensioned by oil pressure, and if the oil drains out of the system, it take a heartbeat to build up pressure to the point that it can tension the chains. During this period, you can hear the chains rattle. > My personal experience is that I know for a fact that large fleets of > b-100 dodge vans with slant sixes were using Fram filters back in the > 70's (early 80's too IIRC) without any problem.

Fram filter may be just fine 99% of the time, but I don't like the way they are made. I don't like the paper end caps, the sloppy gluing, the crummy bypass valve, or the hard rubber anti-drain back valve of the standard orange FRAM filters. The higher priced Tough Guard filters are better, but cost more than better quality Motorcraft or Wix filters. > I recall there was an issue with the slant six oil filters.

You can find plenty of horror stories regarding FRAM filters. I am sure you can find some related to other brands as well, but I think FRAM filters have generated more horror stories than all the others combined. I don't buy the compressed air theory. I've seen filters installed at all sorts of angles. They all get air in them when the engine is shut down. Ed

Stratford is just down the road - home of Fram/Allied Signal Canadian operations (and Kralinator too) Right next to Cambridge, home of the Corolla and a hop skip and a jump from Ingersol's CAMI plant and Woodstock's RAV4 and Hino plants.

'nuff > said. > > nate The important point, for me, was that so many people jump on this bandwagon and there is very little or no objective data on the subject. This business of cutting open filters and declaring them good or no good got a lot of this started, and it had no relevance at all. |
