Ive been doin some engine shopping for my 91 xj. I missed out on a 93 engine with 106k on it. snooze u lose i guess.

I found a few engines at another junk yard about 3 of them out of 95 grand cherokees and 1 out of a 93 xj. They are already pulled eninges and the mileage is unknown. The 93 xj engined look pretty rough, it was oily and the numbers on the valve cover sticker were all wore away. 1 of the 95 grand engines looked real good the vavle cover stick was in perfect shape and it was pretty clean.

I dont know if the condition of the valve cover sticker means the engine could have low miles or not.

so any help on how to spot a good eninge would be great. And will a 95 grand engine work for me? i notice the injectors are different and a few other things.

Ive never done anything like this so any help will be great.

 

And the junk yard engines are sitting with out oil in them. Should that be a concern?

bump.

 

you motor is a renix 87 to 90 years are different than 91 and up

 

no mine is a 91 4.0 HO.

 

His is a 91. Renix is 87-90.

 

Huh? Might want to check the orginal post- he's got a '91.

I think maybe one way to check the condition of a motor is to pull all of the sprark plugs. If they're all nice and tan with very little build up (expect some though) then you should be alright. If they're all oily or black or otherwise damaged then stay away. And if they don't have spark plugs still in them then look elsewhere.

good luck

 

oops gotta quit watching tv same time as forum

 

wow im way off

 

haha no prob.

 

good call on the pullin the plugs. ill do that.

 

if they want to sell the motor bad enought tell them you want to hear it run b4 you buy it its a lot of work to put one in and think its god because the guy at the junkyard said it runs

 

its such a guessing game with these engines. i wish they only had one so i wouldnt have to choice lol.

so what about using a 95 grands engine?

 

i would not buy a junkyard engine unless you can heard it run... i also would not buy a motor unless it still has oil in it The oil can give you a good history and condition of a motor... the grand cherokee motor you have to change all the sensor... and some wiring...
How much are they asking?

 

well the guy said they woulndnt waste the time and pull bad engines so they are tested first i assume. and he said id get a 30 day warrenty.
I just want to do all i can to avoid putting in a engine and then have to do it again because i picked the wrong one.

 

should work using all the sensors from you motor will make it a lot easier of a swap
