Patch doesn't start as well as my 1992 project. Hasn't started drama free in years. Few years ago I ruined the IP on bad buggy Biodiesel. I replaced it with a blowout special wonky IP that required 1/4" of a turn advance to keep the smoke down on/after startup. It ran and started good after fogging the street on the first startup. Replaced the glow plugs as some Duraterms were burned out a couple years ago. It has hi psi pop injectors that were replaced after the buggy IP. It's just gotten harder to start lately.
So I finally got around to getting the wonky IP off and installed a used IP that came off an engine that lost the valves and quit running. Pump sat for a couple years.
Still a hard white smoke startup. Now it's worse: When revved up the engine misses, engine shakes, when revved up. Runs better with a load, but, smokes white/blue vs. the pump that just came off. Engine has a loud knock under load from the pump swap. Thinking the IP may be bad or it's making bad injectors worse. One injector has a body leak. Injectors are not suspect from miles alone.
No blowby. Only other thing I can think of is sticking valves or a bad cold seal on the valves.
