I just got done re-timing the SL after having it skip a tooth or two post-storage startup. Cam timing appears spot-on (no degree wheel available), ignition timing 12^, no codes, completely stock (except Champion R9YC gapped at .035). The problem is that it bogs at low gear, builds RPM and boost VERY slowly (the GLH is WAY more responsive and it's all stock also). I suspect I'm still one tooth off - the question is which way to rotate the cam (one tooth forward?).
On a secondary note, after storage I appear to have developed a coolant leak somewhere on the driver's rear corner of the head (it wasn't there prior to parking last summer). Aside from the bolt on the side of the head (near the airbox mount) and the headgasket, is it possible I may be leaking from one of the manifold studs?
