So tell me if this is a problem or not...I don't know if the original studs actually reached into the water jackets of the manifold (I did not pull them). Tonight I threaded the new stainless studs into the timeserts & they pretty much insert to varying depths...some penetrating too deep to get a washer & nut on. Are the studs SUPPOSED to loosely screw in at the proper (equal) depth and then rely totally on a thread sealer (ARP?) to keep the water out of the very same joint I just welded up? What's the proper method for studs, timeserts, and thread sealer?

If your studs are loose just sitting in the threads then I'm thinking they may have been installed using cheap tools. Cheap taps can throw tolerances off.

I suppose I can get some longer studs on the few and use a good sealer...but it seams like the thread contact would be the seal-point, not the bottom. Were your EMI manifolds the newer dry flange or the older style wet flange joint?

All at once so everything sets in place. When you tighten the nut while holding the stud. nut and insert become tight.
