Oil gelling in RX series

We purchases a 2005 Lexus RX330.  I’ve been reading a different thread about
the RX300 having an oil "gelling" problem that lead to engine failures.
Was that problem fixed in a redesign for the RX330, or does the problem
continue to exist?

Thanks

    Stick with a quality synthetic oil (Mobil 1, etc), change your oil every
    6-7K miles and it should be a nonissue.

    It only happens to people that dont change their oil regularly.

    Actually if you are going to use synthetic oil, just change oil
    (if you regularly put on 12000 miles per year) twice a year.  And
    if you are on a budget, change oil and filter in the spring, and
    just change the filter and add a quart in the fall.  Even when you
    have 6000  miles on your filtered synthetic oil, it is better
    quality than new mineral oil.  But I do know that many people are
    simply indoctrinated into changing every 3000 miles.  If it makes
    you feel good, then by all means…  however it is simply a waste
    of good oil. And I hope if you do change much too frequently that
    you save the old oil and give it to someone who is currently using
    mineral oil.  The only harm that could possibly come from re-using
    this oil is if the oil is contaminated to such an extent that the
    filter does not remove it.  in other words  no problem….  as
    long as it is translucent in a glass jar (amber in colour) it is
    fine to use.  When i use synthetic oil I wait till it turns a bit
    dark, then change filters.  right away it cleans up to transparent
    again…  I wait till it again darkens then i replace both the oil
    and the filter.  This is usually about 9 months of hard use.
    (12-15000 miles) Never have I had an oil related problem.  And I
    used to have a machine shop that rebuilt 10-15 engines per day.
    Most people waste huge amounts of synthetic oil needlessly.

    the actual problem was inadequate clearance in the
    valve cover baffles. the updated valve covers
    weren’t introduced until mid-2001. the new moddel
    you shouldn’t have any problems with.

    however, this doesn’t mean that you don’t have to
    change your oil every 5,000 miles

    having rebuilt about 20 of these, i have not seen
    a single one that wasn’t the victim of 7, 10, or
    20k oil change intervals :/

    Ben-
    Is there a value add to changing the valve covers on a RX300 for a
    model year 99 or 00 to ones used on 02 and later models?  Thanks.

    as in, is it worth it? you could do it, just get a
    quote for front and rear valve covers, pcv valve,
    and valve cover gaskets. as far as it being worth
    it, it would only make sense to do it if your
    lexus dealer wasn’t going to cover the repairs if
    indeed oil gelling has occurred.

    so, IMHO yes, it can be done, but i don’t think
    it’s worth it.

    Interesting.

    Ever try using a better grade of filter? What filter do you use?

    The water will evaporate. So will volatile (short chain) acids. It gets hot
    in there. The additive package (which tends to be excellent in synthetics)
    takes care of the acids, anyway.

    I tend to use Mobil 1 synthetic in our vehicles, but I don’t change it until
    about 7,500 miles.   Still recommend changing every 5,000 miles?

  13. admin says:

    Would you also recommend that in a ’98 LS400 with 77456 miles?

    i think that people miss the fine print when they
    read their meaintenance manual. they see 5,000
    miles service, and they see 7,500 miles service.
    we recommend 5,000 miles for severe conditions,
    such as, extreme weather conditions, frequent
    short trips, excessive driving habits, or for
    towing. here in the northeast, we have all of
    this. if you live anywhere below the 38th, driving
    highway miles all the time, and you don’t tow
    anything, then follow the 7,500 schedule and you
    will have no problems.

    today i pulled the drain plug on an ’02 IS300. the
    last oil change was 12,000 miles ago. the oil
    dripped out like chunky black honey. don’t tell me
    that’s lexus’ fault. hmmm, i wonder why it was
    blowing smoke, let’s see. maybe if the previous
    owner hadn’t spent so much on his pimp lights, he
    could have gotten his oil changed a little more often.
