Nope, any mechanical diesel can. I had a hand cranked 2 cylinder diesel running an air compressor bump off TDC when it was being cranked to start, started backwards, pumping exhaust out the air filter, suckling air through the muffler. Scariest part was the 18" crank handle that cams out when the engine fires, if it fires backwards though it won't come loose, and starts flailing at camshaft speed...
