I can tell you that if your turbo seal is blown you can pop off the exhaust flange on it and you will see the oil on a white towel held up to the outlet when you race the engine. That is for the exhaust side.
Pop the inlet hose off and do the same on the blower side just before it goes into the manifold. Don't do what I did and just remove the hose and race the engine. My turbo uses that quick 90-degree bend hose that goes to the manifold and I got a nice spray in the face as I leaned over the IP to race it up. Put up a towel to keep from being blasted.
As for valve guides, they can become dry and maybe get soft again once you run them some. The danger there that I can see is that you may wear them adversely and they will never seal up again. Kind of a catch-22 where you need to run the engine to get them oiled but in doing so you may mess them up.
Rings might be a problem too. Running the engine should get those to work as they should but at times I have heard that they get bound up when they dry out and they don't expand like they should. Might be from the coke in the burn of the diesel that does that.
Nice to see you back on the forum after all this time.
