"The engine started smoking above 1,700 rpm and then grew worse. When it began smoking at 1,000 I emptied the fuel tank, changed all filters, replaced the feed pump, and replaced the injector tips. Though the valves were sticking, the compression is currently to spec and I suspect that the injector pump is adding to the fuel which is causing the valves to stick and the engine to pump out smoke. The engine has about 3,000 hours on it and currently I intend to pull injector pump and send it out for service."
