Steve,

Mark S.

Mine does as well =96 bolts to the front cover. I have n= ever had a starting issue, but I have followed this discussion with interes= t because a couple of years ago I did a starting spark check and found the = sparks considerably weaker than the mode 8 (or whatever) check.

I recall giving it some thought when doing the wiring (My EC/EM manuals= apparently predated Tracy recommended wiring diagram). I concluded that th= e various things bolted to the engine, like the manifolds, would provide go= od conduction paths regardless of the sealing between layers =96 and the 20= B has a couple more layers.
