    98 Plymouth Voyager has noisy lifters, oil level is ok. Any
    suggestions out there? Rog

    the oil level is ok now, what about the past history of oil changes?, How
    many miles are on this?

    Is this a 3.0L Mitsubishi engine? If so, do the lifters quiet down after
    start up and the vehicle gets a chance to warm up?

    If so, I've seen marked improvement in a 130K mile 3000GT with that same
    dual cam engine using Mobil One 10W30 synthetic when compared to regular old
    10W30 oil. YMMV.

  5. My 97 GC with the 3.3 V6 had that problem at ~25K miles. The lifters were
    replaced under warranty.

    The cause in my case was my short 4-mile commute. In the winter time the oil
    would form sludge from excessive water in the oil (water being a byproduct of
    combustion). Since my commute was so short, the oil didn't get hot enough to
    allow for the water evaporation to occur. The resulting sludge clogged the oil
    passages to the lifters and they became starved for lubrication and eventually
    started to stick.

    Since I had the lifters replaced, I change the oil ever 3 months or less in the
    winter months, even if I've only traveled 2000 miles or less. And, I use
    synthetic oil (Mobil-1 or Castrol Syntec...whichever I can get). I also try
    and get her out on longer runs more often, when I can. I haven't had even a
    hint of the sludge problem since.

    Not sure what you can do once the lifters start sticking though, except replace
    them. Perhaps some others here have some ideas.

    A good engine flush, followed by adding Lucas oil stabilizer or
    Bardahl2 will often clean them up and get them quiet.
    A quart of Dexron ATF in the crankcase for a 50 mile run just before
    the change is a gentle, yet often effective flush.
    The 3 month max oil change limit is the key to preventing the problem
    in the first place, and synthetic oil tends to be more stable than
    dyno oil - but keep in mind it STILL needs to be changed every 3
    months in short trip winter conditions - so I believe it is a waste of

    You forgot the castor oil and ex-lax. :)

    I've never had problems with Mobil 1 and I run it in winter in PA and
    for more than 3 months at a time. Then again, I drive regularly which
    probably helps most of all.

    If you drive more than 20 minutes at a time AND get the oil
    temperatures over 180F sludge is not usually a big factor - but the 10
    minute max run, with oil temps under 180, and any oil will give you

    A treament of Seafoam will remove the sludge and then moisture.

  11. I used to add some Marvel Mystery Oil to loosen up lifters. Not sure if you can
    still get it.

    Yep - sure can - I use it all the time as a sludge preventative in my
    2.7L engine. WalMart and most auto parts stores carry it. Sea Foam and
    MMO both work well (and so does ordinary ATF).
