Hi people

Hope someone can shed some light on this matter. I have just purchased a 03 jeep cherokee 3.7 petrol. The car has just had a brand new radiator, spark plugs, coil pack and exhaust unit fitted. The car has started but is still chugging and blowing smoke. A compression test shows that there is some power lacking but there are no engine management lights on, my mechanic thinks it could be a cracked or bent valve however i have been reading about this ASD issue, can anyone shed any light???

 

My friend's Jeep had a misfiring issue. Check to make sure there are no cracks in the head. He replaced the head and the misfire was gone.

 

Do you have the compression readings?

 

Hi. Yes the car was compression tested and only reached around 175
