Hi, I have a 1982 diesel rabbit with the 1.6L engine in it. It smokes pretty badly. It's a bluish smoke so I'm assuming it's oil. But I could be wrong. When I turn my air conditioner on, the smoke basically goes away. It'll puff a small amount when I accelerate but thats it. When I cut the AC off, it goes back to belching smoke. What could cause this? I don't know much about diesels. Thanks! Josh

The best place to start would be a compression test
diesels will start to smoke when compression gets low
this could be caused by worn or carboned rings, or burnt valves.
