	What usually goes bad.  I am not too worried about valve cover
gaskets or even oil pan gaskets.  BUt if a front or Rear seal goes bad
then I will be a little upset.  I can handle dropping an oilpan to replace
the gasket but pulling an engine to do a seal is not my idea of fun.
Afterall, the Front subframe has to come out to replace the bushings
eventually anyways!

	I just read an interesting page on the internet talking about all
the Nasty polymers that are added to a base oil to get these
charachteristics and that these could cause valves to stick, etc.  Wow, I
never knew that.  I think on  the newer 4kq I will use 5w30 in the winter
and 15w50  Mobil one in the summer.  Better to switch I guess.

	Wow, that is pretty cool.  Guess they need an oil that can Be All
That IT Can Be.   Or maybe thats the Army.   Oh well.
