I'm considering purchasing a 99 E300TD. I've never owned a diesel before but I usually do a lot of my own wrench turning. My truck, girlfriend's truck, my 300ZX, Audi S4, SC300/400s I used to own, etc. I'm not a trained mechanic or anything but I can generally follow Youtube videos or online guides pretty well. Over the past few days I've been looking into some common issues with these cars but having trouble finding many guides/videos on repairs. Once I saw that people build these engines up quite extensively and started looking at OM606 this and OM606 that, I've found some more information. All I've really seen so far is changing the glow plugs and where the plastic fuel lines are that are apparently infamous and from what I've seen they don't look too hard to do.

I do have a garage that does a lot of work for me if it's something I don't have time for and they're familiar with working on at least domestic diesels, but I'd like to do as much myself as I can, because being a Benz, I'll probably need to be getting my hands dirty lol
