Alright so I'm getting a 2000 jeep 4.0 from a family friend he blew the motor. I did locate a motor. salty but I guess this motor is hard to get (so I have been told) $775 plus tax has 134000 on it. I know its not going to be easy,but my first question is how hard will it be to replace the motor is there any tips on how to make the process easy. Also befor or after I install it should I replace anything. I think my last question is what kind of oil should I use full syn ? I want to try and get the best life I can out of the motor I'm buying
Thanks for your time..

 

Just a word of warning, the 00 and 01 Jeep 4.0L use a head casting that is prone to failure- probably why the orginal motor "went". So the first thing you would want to do is make sure you get a warranty with the new motor- something that guarntees its good (assuming it's also from a 2000 or 2001). After you make sure you have that pull the head and take it to a machine shop and have it checked for cracks. If it passes install a new gasket set and swap that motor in. Easy-Peasy.

 

Alright. Is there any other major issues I don't want to put to much money in this for it to become a money trap . preference in oil ?

 

It has been suggested that because of the design of the cam/lifters that the oil should have zinc in it. I run Brad Penn brand oil, as it has the proper level of zinc in it.

So I found out from a good friend if it has a head casting number 0331 those where the bad ones and and ill look around I figured full synthetic was good but ill look.for that kind thank you

 

have 217,000k on my 2001 with no problems

 

I hope I can get that many miles out of the motor I get.

 

you should just take good care of it im getting ready to replace the timing chain and gears cause i drive like a madman n figured y the hell not lol
