I have recently found out that my high milage oil leak is coming out well everywhere not one spot only and in order to seal it up pulling the engine is what has to occur so instead of paying to have an old miled out engine sealed and put back in i'd rather upgrade. I am curious though would a 4.0L HO go in place of just a 4.0L 6 without to many headaches and has anyone done this and can give me an estimation of an average time so I have an idea what i'm in for.Or if it's possible to do.. Thanks

 

cant see why not as long as u have the computer and everything from the 4.0 ho
