i have ordered a new intake and will replace one more time using brand new torque wrench. I would not think it likely that i have cracked head or bad head gasket since i had no problems before the changeout from the 2v to 4v. pulled intake back off fixed problem and reinstalled using hand tightening and it still leaks water into oil then when we reinstalled we stripped threads from head due again to bad torque wrench. the bolt caught just enough to torque down but not enough threads

the second time i used edelbrock bolts and it leaked water into oil so took it off again and in taking out the edel bolts found one bolt had loosened up because it was shorter than the other 11. The first install we used regular bolts and snapped one due to bad wrench. this last time i tightened by hand instead of torque wrench. I always tightened using edelbrock suggested sequence. and it leaks down a couple pounds slowly after maybe 20 minutes with engine off. The third time we got water leaking into oil so had to do for the forth time. A couple of these changes were because mechanics torque wrench was bad and one time we broke a bolt and next time stripped threads in one hole of the heads all due to bad torque wrench. I have installed the intake 4 times now and I still have water getting into my oil. also used rtv across ends instead of gaskets there as reccomended by edelbrock.

gaskets are not slipping because gascacinch holds very well. put ultra black rtv around water ports on both sides of gaskets. I used all edelbrock recommended parts, gaskets, bolts, sealers, gascasench etc. I installed an edelbrock 2121 performer 289 intake with an edelbrock 1403 500 cfm 4v. I have a 68 mustang stock 289, auto tranny, came with 2v.
