Cylinder Head Issues

I have some questions about cracked cylinder heads.

First off, my car is STILL in the shop. It will be one year as of April 4th.

Second, after having the mechanic beat around the bush and give me every excuse, he finally gave me the date of this Friday when he would have the head back on and the car running. Needless to say he called today and has told me the 4th cylinder head has a crack in the sleeve and the sleeves can't be removed so I need a new one.

Then quoted me another $400 for labor not including the parts.

My question is can a crack be fixed? Also my car is a 944S - will the 944 N/A part fit this?

400 in labor - for what? is the head on or off?

had the head a year and he is just noticing this now?

depending on where the head is cracked, it can be welded and machined. anything through the combusion chamber is a no go.

pictures, I want to see pictures....

I went down there yesterday and looked myself. It's not visible to the naked eye, its a hairline, and it doesn't appear to be deep. I myslef think it's just a scratch, but they are letting me its a hairline fracture that more than likely goes all the way through. The only way to even see its there is to actually run your fingers across the inside of the cylinder. You can feel a little very very small groove which they say is a fracture.

Thats also why they say they didn't see it because it was covered in muck until they began cleaning the cylinders to prepare for the new head.

On a good note, the head is beautiful and ready to go.

I'm wondering if it's just a scratch if thats an issue, and if by some chance they are right, how bad would it be to leave it and not replace the small block.

Also with a 951 or NA small block fit an S?

Just got word in a block from an NA will swap out, but I have to swap the pistons as well. Any possible issues with doing this?

Block. The 4th piston cylinder is where this crack/scratch is located.

A 944 short block is made from aluminum, meaning magnaflux won't work :/
