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? |

The hole 'might' be the correct size, but it must be checked and drilled if it is not.
One has to be doing a lot of things wrong to achieve a broken tap on cast aluminum. But I am certain there are peeps who will find a way. (IMG:style_emoticons/default/biggrin.gif) |

You could break off a tap in jello given the right circumstances. |

You could break off a tap in jello given the right circumstances. Yes, as I have mentioned there are very talented peeps out there. The reason I mentioned it 'might' already be out to heli-coil tap drill size, is because the material removed by the OE stud was up to the full 'major diameter'. The Heli-coil drill size for this application is right about 8.3mm Dia. which is approx. 0.0118" (inches) larger than the stud's major diameter. (IMG:style_emoticons/default/popcorn[1].gif) But yes, ABSOLUTELY take the high road and do this the RIGHT way. Drill the cast aluminum to 8.3mm, vacuum all debris then begin tapping with the CORRECT Heli-Coil tap. Using a lot of tapping lube and being very careful not to break the tap in the hole. Because we all know this can happen, even in jello. (IMG:style_emoticons/default/biggrin.gif) |

I knew the jello salad would get attention. And yes, I can screw up a sure thing.
