I have 2 turbos and so far no problem, knock on wood. The only small problem is a small amount of oil seepage somewhere from the turbo of my 82 300D, but it's small enough that I don't have to add any oil between oil changes. It's true about the day and night difference in power between a turbo and non-turbo. As you can see from my sig I own the fastest and slowest MB diesel, plus the 82 300D which is about the average of the two in power. The fact is, I like the 240D as much as the other two and I would even like to add a non-turbo 300D to my collection just for the variety, but I wouldn't have the space or time to work on it. Help, I'm addicted.
