I have a 2005 se 4x4 gas engine with 197k on it, it smokes on start-up, and sometimes even blows white smoke the entire time its on, that smoke smells like antifreeze, start-up smoke smells like burnt oil. Engines burned oil since 163k, starting to get codes for multiple cylinder misfire, cylinder 5 misfire, both cats, camshaft position sensor, sometimes it wont start unless I'm real nice to her. Time for a new engine? already replaced my tranny at 180k, and suspension/lift kit put on at 190k, thinking about going with a remanned engine with a warrenty. While everything is out i was thinking about throwing on some jba longtubes since rumor has it our stock ones crack bad. Whats a good price on a remann and install, or where could i find a quality used one? How much should i look at getting charged from a shop? I don't know much about engines so any help is appreciated. Thanks guys!
