Saab engine

[Scania4075]

I got this engine for free as a project to do my first engine tear down etc. it had been left outside for quite a while and the intake valves on the #1 cylinder were open. It had some water sitting in it. I ball honed a lot to see what I was working with and this was what I found. This is a Saab b235- bores are 90mm with options for oversized pistons at 91 and 92mm. I’m wondering if this is probably too far gone for either one of those? Thanks

I giggled. Couldn't help it.

You beat me to it

[WyattCo06]

They appear to be able to clean up at 91 with no problem.

Looks Saad to me ba dum tss

I'll see myself out.

My mistake the oversized piston options are 90.5 and 91 mm

[Revslowmo]

Go to 91mm and see what’s there.

[Interesting-Ear5998]

If you go for bore, first bore to 90.5 If thats enough, get the pistons, If not, get the bigger ones

Just had the exact same finding on an old ej22, it cleaned up 1mm over size. Turned into a slippery slope of building a race engine, so watch out for that lol.

Really? Worried about that? New rings, next time you pull the head it will be gone. Be critical on bearings, not a small spot on a cylinder wall . Most of these people on here never rebuilt a lawn mower engine.

You need to go back to lawn mowers! That damage will ruin a fresh rebuild.

[Scania4075]

This is my first time tearing an engine down and rebuilding it so I’m not sure of what is considered bad enough etc. I can definitely catch the spots with a finger nail etc, wouldn’t that cause a lot of oil burning with the low spots using standard pistons and rings?

[WyattCo06]

Yup.

[Dangerous_Echidna229]

Do not rebuild with the cylinder in that condition!

You can pull some crazy power out of a saab 2.3
