    FRAM FILTER?! Theres your problem! Dont buy your oil filter from the same place you buy your underwear! Fram is overpriced and underbuilt. They use a oil paper end cap and try to seal a bypass valve to that. A bad filter is a good way to ruin an engine! But, I know you'll say you've used them for years and never had a problem, happens all the time. Good luck!

    Do you have antifreeze in the oil? Very common problem on the vortec 350's for the intake manifold gasket to go bad.

    Have you ran it cold since it started making noises? Also check your oil in the sun light to see if you notice any metal shavings.

    Good luck

    The stp filters are junk too, look up bob the oil guy he has cut a zillion filters apart and compared them. Not saying your problem is oil filter related just throwing it out there. Have you cut the filter apart? A guy on another site roasted a Duramax because the filter collapsed just happened to be a Fram:nod:

    AC Delco are basically the same as STP. Bosch are also made by Champ Labs, along with STP, AC Delco, and most "House" brands - Valucraft, Pronto, Napa Pro-Select.

    For good quality filters, Napa Gold/WIX, Mobil1/K&N, or Amsoil/Donaldson. You get what you pay for.
