Question type: Shopping & Pricing

i had bought the cherokee 4 months ago which appeared in good working
order...unfortunately on a long trip had lost oil ...it somehow escaped from
the actual dip stick tube it has broken free from the engine base i didnt
even get a warning light  then the engine started to make knocking sounds
so pulled over called a tow truck the engine still had some oil in it ...so it
looks like the motor now needs reconditioning .just wondering how involved
is it to repair or upgrade to a bigger engine and if possible to fit a bigger
engine to the same gearbox even to use adapter plates ?

If you don't have to deal with emission standards where you are then you can put in a small block V8. You didn't state what year it is but I am going to assume it is a Chrysler Jeep so a 318 should work, I think if you want to go bigger that you will have to change the tranny as the stock won't handle a bigger engine. Of course this will be labor intensive as you will have to modify the fuel system, redo the exhaust, change the mounts, and quite possibly redo the front suspension to handle more weight. HTH


Sorry didn't see the year in the first thread, an 05 is going to be a bit of a problem as you are dealing with computer controlled vehicle, so going on that I would recommend that you find a wrecked one in your year that has the engine you want and transfer all the power train and computer systems into your rig from the wrecked Jeep, that way you can still have a viable vehicle when your finished, but it will still be a lot of work.

sorry guys my mistake its a 2004 model not sure what initials it is but its definitely a 2,4 liter 4 cyl engine i think a second hand motor would be the best option money wise just need to know where to get one?


An auto wrecker would be a good place to start.
