Tiny, do you carefully tighten the manifold bolts slightly prior to loosening them? I have never broken one after doing that. An old timer showed me that trick (very likely your elder. smile ) I don't know how it works, but it does. I don't know how electricity works either, but the lights still come on and I still get a bill.
