Some world here claim to have actually 137K+ mile on theirs. The only issues I heap (read) human being squawk around is the rings on the pistons are greater than normal, for much better cylinder wall lubrication. This makes supercharging a little iffy, yet there provided to be one because that it. Some have said castle have major oil sludge problems, but I use synthetic, so the won"t it is in a big issue. I experienced a legitimate fight through Chrysler, in 2007, because the dealer would certainly not honor the extended powertrain warranty ~ the engine failure on the guy, due to the fact that they had no proof the oil alters were done. The dealer said, the they gotten rid of the valve cover and found abnormal quantities of oil sludge, which led to the engine to fail. I view it develop up appropriate at the to fill neck, in the item you pull out to fill "er up... The 3.7 had some chages excellent to it around 2005? Dunno really... People who have had actually them longer, would know.

Being realistic, if girlfriend take care of it, never over heat it, and keep the oil readjusted I would expect an ext than 150k at least. Just weak allude that seems to be typical is the valve springs. Tough to tell once they might go. If ns able at 100k ns may get my top rebuilt simply incase.
