OR...........Pull the manifold and run it across a belt sander a couple
of times to make it level, put a new gasket and re-install. To do the
leak detect thing, start engine (cold) and spray ether around suspected
area of leak.......any increase in engine rpm will tell you where the
leak is. Be sure and do it while the engine (exhaust manifold) is cold
so that you won't build a bomb. Fred Martin
