These Nikasils OK? 1980SC

[worn]

I have started to rebuild after Dilivar failure - 1 stud broken for each cylinder all along the bottom left side. Some of the cylinders have pin pricks in them. Number 5 is most pronounced, although not part of the stud failure. I would like you to take a look:


A close up


Most of the pinpricks are isolated, but in this case the defect seems to form a line. Are these reuasble? Is this a sign of delamination of the plating from the base casting? Is it progressive? The car has about 100,000 miles on the clock and at this point I am trying to find out what I need to replace or rebuild.
Thanks!!

Hi.

To be honest, one would need either very hi-res, close up pics, or better yet,...inspection by an experienced professional to tell you whether these are still serviceable or not.

I'd love to help, but your pics are inconclusive.

I have a newish set of cylinders and JE 9.5:1 pistons I ma be selling.

Low mileage. (I'm going all out on my track build)

1/2 of new.
PM me if interested

Thanks Steve,
I just watched your pressure plate video, so you helped me twice already.

I am looking around for experts, but also I removed all the megapixels for the web. Would a more detailed shot help?

Hard to know at this point. I am still hoping. Also, if I replace them I would be tempted to go up a size. Perfect excuse eh?
