If it is an ignition problem, maybe. A cylinder not firing will cause fuel to wash down that cylinder and contaminate the oil in the crankcase. It is probably best not to drive it. > Rebuild the engine to put it back into spec? If the compression is okay, there are no massive oil leaks, and no odd internal engine noises why bother? Do you have that much extra coin laying around AND a wife that will let you spend it? I should be so lucky. > Drive it and save up to do a head gasket replacement at which time everything > would be clean and sealed up by fresh gaskets instead of the 40 year old > stuff? Park it and have the Indy sort it out, if you feel over whelmed by it. I am not familiar with Mercedes alloy V8's. If it is common for particular head problems to arise on that engine, address those issues. If it is pretty much bullet proof, leave it alone. > What other things could be causing a miss? A four stroke gasoline engine needs fuel, ignition, and compression to run. Determine which is lacking, and correct it. I know, easier said than done. Does it miss at idle? Only under load? What are the conditions that cause the miss fire? A shop with an old Sun machine could help here. The old oscilloscopes were great for troubleshooting points ignition problems. I still remember a few things about how to read one. What shows up as point bounce, bad wires, etc. My WAG as to your problem would be a heat related deterioration of the injection wiring. That is a WAG, as I know nothing of Mercedes V8's. Rick Who feels old now.
