Default POLL UPDATE ON 3.8L Engine longevity poll taken back in 2011.

I put this poll under stock but was debating the modified board since I, and others upgrade their Jeeps. I'll start off with mine: 2007-55K=No problems. fwbb
An continuation of the poll taken back in 2011 on 3.8L engine longevity.

117,000 on my 08
137,000 on my dad's 07
Only thing on ours is small oil leaks not bad enough to warrant tearing into yet.

Coming up on 33K. The only problems I have had in 5yrs of ownership are one rear caliper and several HVAC problems, stupid plastic gears, TPMS sensors and rust!
