i've got the "clunk", but funny thing is it only occurs at one place on my commute and so far nowhere else. i've also added about 1/3 of a quart of oil in 2100 miles. what i'm disappointed with is my gas milage...in mixed highway and city driving (about 50/50) i'm averaging only about 18.5 mpg...and i have a 2.7 (the epa averages on the monroney indicated 23 to 32).
