I got my 04 Disco several months ago and I am quickly learning it is a hands on kinda thing. I have experience working on my M114 and M998 from my time in the army and having it for a few deployments I got good at quick fixes which I would like to stay away from for my new truck. I already have the three amigos and a questionable clunking in the engine. I suspect the previous owner used a lower octane, what other things should I look out for or just do now to save myself a headache or where could I find that information either would be helpful.
