Well gentlemen ,I think my 96gt motor is telling me its time to replace it ,its been bucking slightly for about 5 months now, but i could not locate the problem,i changed everthing electrical, well the other day it started doing it again only harder ,i got home from work and my wife says she smelled radiator fluid burning,i checked the radiator and it was very low,i checked the oil, no pudding,for those who have blown a head gasket they'll now what i'm talking about,so the only thing i can think of is that the head gasket has blown between the cylinders,or the plastic intake maybe leaking into the cylinders,it was replaced 3 years ago but not with the upgraded intake ,tell me what you guys think? i did a pressure check and two cylinders were at 90 psi,i think i'm going to put in a 99 motor ,what will have to be done to do this swap?:SNSign:
