Rebuilding my S4 TII motor, questions.
 

Now, since im a novice, I have no clue what is considered what is good, or bad. Most of the housing looks good, but around the exhaust port, there are some scratches. On one housing they arent deep enough to catch a fingernail, and arent raised. On the front housing, it is deep enough to catch a nail, and its raised on the edges slightly. The apex seals did not have damage where these scratches were, but I dont want to have to pull this engine apart for a while.

Thats the housing that I am the most concerned about. Specifically those scratches, the rest of it looks really nice. No visible flaws.

The other thing that I am worried about is the mid iron. It has a fair amount of wear, that matches up to the front housing. It has some parts where I can feel a fair amount of vertical difference.

Im not sure if you can see it in this picture very well, but on what the left side would be, looking at this iron from the front, is where the wear is.

It has some very light surface rust/dust from sitting on my work bench, I havent taken 0000 scotch brite to it yet. 0000 makes it look nice and shiny, doesnt leave any visible scratches.

The rear rotor bearing was bad, and it looks the part.

I havent measured run out on the Eccentric shaft yet, but it looks good, no burn marks, no abnormal wear marks (at least what I would consider abnormal)

Input from someone that knows what the hell they are talking about? Im going to replace everything, even though most of it looked to be in decent shape. No reason to do it halfway, and then have to pull the engine apart again.

I really dont want to have to buy any new hard parts though, a new rotor or housing would really hang me up financially on this.
