Thats a hardend tip to help the dipstick snake through the tube and into
the oil pan, don't worry about it.

sounds like it hasn't had regular oil changes. The 238(3.9), 318(5.2),
and 360(5.9) engines are not known to be sludge motors, unlike other
engines (the 2.7 V6 in the Intrepid is a sludge prone engine) I would
recommend running a full can of sea foam in the crank case just prior to
your next oil change. Also - as per my own recent oil filter
experiance, I would suggest you change the oil filter halfway through
your oil service interval. (if you are going to run 4000 miles, change
the filter at 2000) - as it seems an engine with a little sludge build
up can cause an oil filter to clog up quickly. Had that happen to one
of mine after only a few hours at idle!

Stock 3.9s were never powerhouse engines in stock form... be glad you
don't have a premagger 3.9 :-P

This might be related to the dirty oil. If the lifters are dirty and
clogged - they won't "pump up" as well - and can cause clacking that
will vary with engine speed. Again, a can of sea foam will clean out
sludge and should free up sticking lifters. Marvel Mystery Oil also has
the same uses.
