well if you think theres more oil on it than before the pvc blockoff, its obviously coming from somewhere. Oils got to be coming from the turbo if thats the case so idk how good your bearings are anymore, even if you don't have signs of shaft play now maybe thats gonna start to show with more bearing damage... Like i said i'm just throwing ideas out there. What year truck is it, are you still under warrenty?
I'd jsut use eyther to clean if too, but do what you please.
Whats wrong with using either? I use that to clean everything unless its something that can dry rot.. It works alot better than brakecleaner and its cheaper.
Hence why I said wait alittle, I really wouldn't worry though eyther evaporates so quickly. I also doubt the engine would get addicted to eyther with just one start too.
