Hi Guys,

So...I've finally reached the point of putting the fuel system back on the engine after a refresh and have run into a question. Two of the passenger side intake nuts on my 2.0 (the left and right ones) torqued up to 14lbs fine. The center nut stopped getting tighter at about 8lbs. I assume that the stud is spinning in the head. Would you leave well enough alone and trust that the seal will be fine at 8lbs...or would you pull it apart and deal with the center stud?

I def don't want to put the engine back and then find a vacuum leak...but I also don't want to make a bigger problem where may not be one in the first place.

Thoughts?

Before drilling be sure to put tape over the intake ports. It would be best to use a 'drill stop' to control the depth of the drill. But seeing as how opened up the hole is ... you should be able to 'sense' when to get to the bottom (in the form of additional resistance). I would not push very hard, just be sure to hold the drill straight or use a 'drill block'.

Once you tap the hole with the heli-coil tap. Clear the chips and as an option you can add some blue Loctite to hold the heli-coil in place once installed. The heli-coil should be about 1 thread below the surface before you break the tang. This will help prevent the coil from being dislodged and will also keep the coil threads in good alignment to start your stud. I guess you can add Loctite to the stud as well.
