Old thread here, but now I'm thinking maybe I replaced my turbo for no reason. I suspected the turbo because I was actually getting oil dripping out of the exhaust onto the starter, but when I got the turbo off I see oil is also in the manifold.
I have not run the deuce harder than idle in about a year, because I've been very slowly taking it apart and painting it and adding a winch. I do let it run up to temp at idle at least once a month (I thought that would be good for it) but now I'm wondering if all this idle hasn't lead to a build-up of oil in the exhaust and now I just need to get her out and run harder to clean it out. I guess time will tell.
