I am getting ready to rebuild a 2.0 liter four, which happens to have Mahle pistons and cylinders. I know Mahles are really good, and it seems like they would be better than most aftermarket P&C. So, assuming they are in good condition, is it recommended to reuse them? If so, just use new rings? Has anybody here reused theirs in a full rebuild?
This engine is being built for durability for One Lap of America. Suggestions? I know AA P&C have had mixed reviews. If it is not recommended that the Mahles be reused, what is recommended? |

I have reused pistons and cylinders . Pay close attention to cylinder wear as others have noted. I would use a deglazing hone on the Bores. And if your going to clean your pistons.... never glass bead or sand blast the ring grooves or ring lands. I am going to rering a 1.8 here soon myself for my Sons car.... Good luck
