I had my 3.9 from 34,000 miles to 105,000 miles. Mine ticked the entire
time I had it. Never had any serious problems with the engine. Replaced the
water pump around 90,000 which is to be expected. I even did some "messing"
around with the engine. Drove it on the hard side. I upgraded to the 4.7
with my new truck because it got the same mpg as the 3.9. Otherwise I would
have gotten the 3.9 again.
