I wanna pull on your coat about something...
I recently bought some used S5 housings to rebuild my old 87 NA, I have a few questions reguarding their condition.
First, both housings have had their pitch diffusers ground out.
As seen here:
And here:
As you can see from the pictures, there is some material missing from the edge of the exaust port. As these housings are going to be street-ported, do I need to have these replaced?
Secondly, one of the housings seems to have some iron deposits encrusted in the water jacket. This stuff blows off easily with a brass brush on a dremel tool but I cannot get into everywhere with it. Should I have it ultrasonically cleaned? Phosphoric acid perhaps?
Here's a pic or the deposits:
And lastly, the same housing pictured above has a few pockmarks in the water jacket. The worst of them is pictured below.
Are any of these issues an area of concern?

This is what happens when coolant is neglected, or too much water is run with no corrosion protectant (coolant).
As for the very light pits on the surface of used housings, that is why I use a light coat of sealant on the rotorhousings during assembly. IT fills in any of the pits that might cause a sealing problem.
