can any one help me I have done research and hve found nothing.
will a 1993 cherokee motor fit into my 1990 cherokee. I think that the 93 is a H.O and the 90 isnt. Im not sure of the wiring. is the blocks at least the same thanks scott oh any help in this matter will really help me in my trip to washington state from florida. my jeep has 195600mi and the motor is in need of replacement. I graduate navy dive school in march and its a long trip up there, just want to be sure to make it thanks again.

what exactly is wrong with your current motor?

if i were you i would find an exact match for replacement to help avoid any computer related problems you may have.

not sure, but i believe the 93 is injected, and the 90 isnt... so ull have quite a bit of stuff to swap, if im correct.

91 was the 1st FI models right?

once again, you need to find an exact match to avoid computer problems.

and also again, i believe the 90 is a carb and the 93 is FI. or was it 95 when they switched? i cant remember.

just so i'm on the same page what engine are we talking about? I have a injected 4.0 in my 87.

well i know they started put FI in wranglers in 91. so i would think they did the same with cherokees... so confusing... post pix of the engines. then we can tell u for sure.

welp another situation where my yj knowledge didnt help. sry if i complicated or confused things.

Kyle

not a problem at all

it is very odd that Jeep switched from carb motors at different years, who knows.

ok my motor is the 4.0 6cy and the one i want to put in is a 93 h.O motor and it does indeed have a differnt wire set up. but my main thing thant I cant come up with on my own is if the blocks havent changed from those years. becasue all of the other parts in the motor are good ie the intake/exhaust manifold, throttle body, all the sensors, as long as there is not more holes and ports on the newer motor for sensors and stuff that the old moror doesnt have. and some one asked whats wrong with this motor.
it has smoke that escapes out the vavle cover vent, the vent that is suppost to go to the airbox for recerculation. but is disconnected becasue it also has a slight oil spray @ highway speeds or higher rpm but no smoke from exhaust. witch is weird i figiurde it was blow by but i dont know. it also has a lot of oil gung build up inside the motor witch is bad. i took the valve cover off to see why oild was misting out like i said and scraped enough gunk out of the inside of valve cover to fill a soda can real nasty. so i figure the rest of the motor like inside of the crack case will also have this build up do to neglect of the previouse owner. thnaks again u guys scotty
