working on a 69 4.2 e type, auto, 2+2. Has less than 1k since head was off for valve replacement. Unrestored car, starting to show its aging. Either the input shaft or oil pump seal on the tranny is leaking, and the bigger problem, timing cover/block/head gasket junction is leaking(along with front seal) The oil pan gasket could use replacement as well. Now comes the question, due to the front cover oil leak, the new head gasket, and the fact that the head gasket to timing cover doesn't seal the cylinders or water jacket, if the studs in the head were removed(front underside of head, on cover) and the oil pan, could I remove the timing cover without pulling the head? I am planning on pulling tranny, but with the front cover work(and possible head removal) would I be better off pulling drivetrain? Speed is of the essence, special tools not an issue.
