Corrosion around cylinder bores

[Mattasmith12]

I have a case that was cleaned and bored for 90.5 cylinders. Unfortunately, the machine shop found some corrosion around the bores. Am I right to assume this case is garbage now since the cylinders won't seal correctly?

It'll seal fine, why wouldn't it? None of that damage connects a point from inside the engine to the outside, and you're going to use sealant anyway. I've always used silicone in this area of the engine, but nowhere else!

I'd run it. It is not in a pressurized oil stream so the silicone will do it's job and seal it up.

cut deck .100 use spacer for right deck height:D

[modok]

it's alrady cut .040 approx

dab 518 in the pot-holes, it'll work

Whoever did that must have a pretty sharp flycutter for it to clean up that good, looking at it beforehand I bet you didn't think it would turn out that clean.

looks like a good job but should of went about .040 farther. shims are sheep...and seals are wet....unless there sunning them selves.

matta, very good work with your photos- sharp, well lit. Wish I could reach thru the computer and run my fingers lightly over the machined surfaces.

Who did that machine work? Looks like EMW in Hawthorne.

Permatex ultra copper silicone to seal cylinders to case....
