Oil filter fit question

Discussion in 'General Motoring' started by Daniel Who Wants to Know, Feb 9, 2007.

  1. I am researching various filters that fit the 3.3/3.8 and have learned so
    far that there seem to be 4 different ones that have the correct threads and
    gasket diameter for the block. Going by Wix numbers: 51085, 51515, 51775,
    and 51773. My question is if the 51773 will fit without the end hitting
    anything or hanging too low where road debris could hit it. Other than that
    spun #1 rod bearings in 3 different 2.2 engines using fram filters for
    regular oil and filter changes has made me avoid them like the plague.

    What unique aspect of Fram filters caused the rod bearings to spin 3 times?

    If you are willing to invest $10 in the future of your car, purchase a
    new FRAM and a new WIX filter for the same application. Now, saw the
    can off as near the base as possible. Tthe quality of the bypass
    valve alone will cause you to never buy another Fram. Now, look at
    the "end caps" on the filter itself. Fram-cardboard / Wix-steel.
    Now unroll the actual filter material and compare how many Square
    Inches of filtration you are getting? Amazing isn't it....

    By the way, when that "bypass valve" pops open it floods the bearings
    with all the grit and debris that has been building up in the
    filter. Poof!

    Another WIX number to consider is the 51452. It is actually
    specified as a "severe service" filter to replace the 51085 on Dodge
    Trucks. It has a thicker metal canister than the 51515, and I seem
    to remember that the Microns of filtration are somewhat smaller as
    well.

    I and all of my buddies with Mopar products have been using the WIX
    51515 for more than 15 years to replace the "shorty" 51085 and I
    highly recommend it.

    Good Luck, Bruce

    It SHOULDN'T do that. When the bypass valve opens, it still keeps
    positive pressure and flow through the filter as always, which should
    keep built up debris pinned to the filter media. The bypass is direct
    from input to output in parallel with the regular flow through the media
    and shouldn't get any sort of "backwash" from the filter media
    whatsoever. The only grit that will get passed through the bypass valve
    is the grit in the oil CURRENTLY coming into the filter.

    I'll never use Fram again, although I used to about 10yrs. ago. I've
    heard and have had first hand experience on horror stories regarding
    fram.. I recommend factory replacement..or WIX.

  6. #1 may not have been entirely the fault of the filter, Friends installed a
    new A413 transaxle in our 89 yellow Sundance when 3rd and reverse went out
    but they didn't get the kickdown cable adjusted right so it would downshift
    up the smallest of hills and not shift back up until we let completely off
    the pedal. We told them and they took off down the highway with the car
    floored which of course wouldn't allow it to upshift at any speed and they
    spun the bearing. I'm not sure if they redlined it or what but it came back
    knocking. Had the engine replaced by another friend.

    #2 1 month after getting back from a road trip to Florida to pick up my
    sister the head cracked from thermostat not opening until the temp gauge was
    almost to overheating then the temp slammed back to cold as the coolant in
    the radiator rushed to the hot block and head. A few months earlier my
    sister backed into an iron I beam light pole and creased in the back of the
    car so we decided to pull the engine and tranny among other parts and store
    them as extras. Bought another 89 Sundance with a bad fuel pump this time
    grey with what appeared to be an older engine as it had the square tooth
    timing belt and the blanking plate where the mechanical fuel pump would
    mount. Changed oil, filter, fuel pump, and fuel filter and drove it for a
    few months then it spun yet another bearing.

    #3 Replaced the head on the other block and put the engine and trans in the
    grey Sundance. After test driving the car around to warm it up I looked
    under it with it idling to check for leaks and the engine stopped. After
    restarting it several times and having it idle for a few seconds and stop
    each time I started it again and held the RPM at 2500 during which time it
    bogged down a few times and was then that it started knocking. The oil was
    still full and it didn't get contaminated when the head cracked because we
    didn't try to drive it that way so it didn't get any coolant in the oil. I
    guess hindsight really is 20/20 because had I known that the engine was
    seizing I wouldn't have restarted it after it died the first time but at the
    time I didn't suspect oil because it was full and the light never so much as
    flickered after it was started.

    I agree with Steve. Look - I'm not a defender of Fram, but if you're
    going to criticize something, don't make stuff up to over-state your
    case. Your case should stand on its own merits.

    Also, your argument is pointless unless you identify which model filter
    you ar talking about. Some of your comments do not apply to, say, the
    Fram ToughGuardâ„¢, which is reasonably priced.

    I've been using Proline from Pep Boys for years. Someone other than I
    did a teardown similar to the one mentioned earlier in the thread.
    Proline looked pretty good in that analysis.
