EPIC nuts/studs loosening thread (reposting stupid stuff without reading = warning)

All mating surfaces were trued before reassembly and copious amounts of Resbond 907TS threadlocker was used on the EM studs (torqued to 10-12 ft-lbs).
You can see just how beefy the 10 mm studs are. I didn't take a side-by-side picture, but there's much more meat to them than the +2 mm would indicate.

Putting everything back together with the bigger studs proved challenging. My mechanic switched out the lower exhaust manifold studs from a Nissan (IIRC). The keyed end allow you to install the stud with the exhaust manifold in place and apparently made a big difference.

My next track day is tomorrow. Fingers crossed that this finally fixes the problem.
