oil change

[mikeyo]

i know i should have sorted this out by now, but i'm forever more confused. rodney measured his dipstick for me, which turned out to be the same length as mine, but i'd like to know how far up the dipstick does it read 'full' and 'add more'. if i put 5 or 6 quarts of oil in, i read way above the full mark. thanks guys

Chrysler issued a technical service bulletin  no. 10-02-77 P-6332-C on 12/5/77 which addressed the dipstick issue.  The original part no. for 1977 and prior B200-300, CB300-400, MB300-400 with 400-440 engines was 4089656.  The new one was p/n 3821675.  Basically they re-calibrated the stick to the following dimensions:  33.12" from distal end to middle of collar that stops the stick from going further into the tube.  The full mark is then 30.12" from the middle of the collar.  The add mark is 1.06" further.  Just measure your stick and you'll see which one you have.  It is a simple matter to scribe new marks.
