How easy is it to crack/break the intake manifold. i put in a y7 in my eg on friday and it ran fine minus the irratic idle. i had no luck locating an iacv so i put on a d15 intake mani. once it was on i remembered coolant leaked around the gasket into the 4th cylinder so i figured there was somthing wrong with this mani. (did the same thing on the d15 motor) took it off and put the y7 mani back on the y7 with a new gasket and then my friend broke the stud right beside the coolant line on the intake manifold(over tightened it). i put a new stud in the head and tried it again. now, as soon as the thremostat opens and the coolant starts flowing i get white smoke all over the place just like the d15 was doing. whats the solution? I'll head to the junkyard tomorrow for a new IM if that will solve it. lmk what your opinions are to fix the problem. Thanks to all in advance.
