Default Scratches on Cylinder walls okay? w/ PICS

Been tearing apart a project car I just bought. Been trying to find out whats my best option on rebuilding this motor. I already got my head rebuilt. What do you guys think about the cylinder walls? block as 180k on it. Some of the scratches catches with my finger nail but nothing crazy. If it is bad what are my options? Sleeving or can I just put in in ap2 piston rings and call it a day?

If you can catch your fingernail on it, start looking for a used short block or sleeves.

I'll be cracking open mine soon, hoping to put in new rings and run with it . I'd be curious on what route you choose be sure to update us

From what I am reading and hearing if the cylinder walls have any scoring that catches your fingernail its not a good sign. So i am either going to sleeve this block or try and find a used good one.

I talked to my friend that owns a machine shop he said he can machine the old sleeves and put in replacement sleeves that are made out of steel? He said because i am not looking to make big power just to get the car back on the road there is no need for me to spend on darton sleeves. Anyone done this or heard about this?

In your instance you would hone the cylinders if possible. Forget the manual, you can use a silicon carbide manual hone(ie dingleberry) use lots of honing oil and work slowly. 800 grit or finer. Toss in new rings and send it. That's your best cheapest and most reliable option. Frankly the bores don't look too bad at all, do any of the scratches that catch your finger extend the full length of the bore?

Or you can put in sleeves and use regular pistons, probably second most reliable option if done properly. You cannot use FRM pistons on a sleeved block.

Yes some of them scoring is caught by my finger nail but not bad, and no none of them go all the way down.. does anyone know about steel replacement sleeves and running oem pistons? Reading up that sleeving these motors they dont last long.. I dont want to spend 3k on a block and only last 5-10k miles

I may put the motor back together and see what happens cuz my only best option i see if to find a used motor or block and go from there. I dont plan on boosting this car so its too much money to sleeve and lose its reliability
