My 1984 280SE (Euro) 240k km., was misfiring occasionally at higher revs. Blue sparks on the distributor cap, (corroded coil terminal, probably the original cap!) 2 (!) plug electrodes almost eaten away, so changed all HT leads, distributor cap, rotor arm, oh and new plugs ! Now pulls strongly from 2000 to over 6000 rpm, but idles like a 5-cylinder. No oil in the water, no water in the oil, spraying diesel start around can't find any intake leaks. Are we talking head gasket between cylinders, or leaking hoses or what ? Any help appreciated. David Westerman
