Hey guys and gals! Just bought my 16 year old daughter a roughly used 2001, 4.0l Laredo with 166,000 miles on it. The body is very nice with the only visible rust being very little on the inside bottom driver's door. Undercarriage is solid as well with some minor spots. I paid $1500 for her with some known issues and some unknown.
So far I have replaced the trans pan with filter(near rust through), radiator, rad fan, fan switch, thermostat, and passenger window regulator (easier than most Chrysler products by a long shot!!!).
Future parts starting next weekend will be the exhaust (from the headers back due to cat pipe elbow rust thru), all new brakes, pads, rotors, calipers, tires, rear main seal, and valve cover gasket.
Now, the questions you all were expecting. There is an obvious oil leak on the passenger side between the head and block. There are no obvious signs of oil intrusion into the coolant or vice versa and while I do lose coolant I can see it run from the backside of the overflow reservoir when it is to the "fill" mark (I suspect I need an overflow tank added to my parts list
Concerning this leak, I have seen very little traffic on this but the little I have seen appears to blow this off as a "jeep thing." Having the dreaded 0331 heads do I go ahead and change the heads and head gasket or wait until something major happens (leak becomes a flow, or heads crack).
Obviously, having no prior knowledge of the maintenance of this vehicle I am wary of everything but she has survived 166k miles and still runs well, albeit with obvious maintenance issues. The engine runs out strong (with a tap, tap, tappy until warmed up), the tranny shifts well, the heat works, etc., etc.
I have five-six months to turn this rough running vehicle into purr-fection for my daughter. What are some of your thoughts? Change the head/gasket or wait and see?
