The stainless shaft that turns the oil injection pump runs off a plastic worm gear on the crank. The shaft wears down, the teeth get sharp and they will eventually bite into the plastic worm gear. I have seen dozens of mangled worm gears . . . very common failure in the 2.0L, 2.4L and 2.5L mercs. I have heard ethanol will swell the plastic which accelerates the wear, but I suspect that is shear speculation. It's really just a matter of time before this happens. There are tons of 1978 - 1983 mercs still running great without oil injection. With Merc's oil injection the oil and gas are mixed in the fuel pump before they enter the carbs, so what difference does it make if you mix oil and gas in the tank or in the fuel pump? I personally think that eliminating the oil injection reduces the potential problems (like the oil pickup screen getting clogged, worm gear failure, air leaks and broken oil injection tubes, forgetting to fill the oil injection tank, Making a mess in the bilge). Removing that oil injection system really cleans up the motor too.
This is just my opinion based on what I have seen and read, you have to make your own decision.
