Shop here wanted 80 per cylinder, pay the 28So i took a 318 apart thinking it would be a quick hone and ring slap.
When i took the pistons out, 4 out of 8 had broken top rings. Pretty ridgy, which is strange the broken rings didn't damage the walls and it still ran like that, I drove it in the shop!
I was thinking it was smoking because of bad valve stem seals, which is probably true.
So now I'm looking into boring it out. I got a quote of $28. A cylinder to bore it to any size i want.
So that's $224. For a 318
