So my other topic is not getting any response, let me try a different approach. I know the guys, who know, are out there. This is a 96mm p & c combo that came out of my 1911cc. These are old school. I know for a fact that this engine was modified at least 20 years ago (the car has been stored that long). I have never been able to find part numbers or marks other than the "TS" inside the pistons. The cylinders have 18 fins, don't know, if that helps, with 24mm wrist pins. What I would like to know is if they are usable / worth salvaging for the rebuild? I'm on a budget. Car needs extensive fire damage repair.
As you can see, this piston suffered from some corrosion and has pitting. I am aware that there are engine parts that can be welded/metal deposited where there is pitting. Question is, is this piston repairable and at what cost? I also need two 96mm jugs to replace two that are also pitted (easy part) . TIA for the advice. -Dan Attached thumbnail(s) |

There's no damage to the piston, that's just the result of normal combustion. You could, and I often have with my own cars, re-use the piston and cylinders. Just clean the pistons well, re-ring them, and hone the cylinders. Make sure you get all the carbon out of the grooves, and you can use the new rings to check clearances are good.
Proviso is that for some reason aircooled motors don't take to re-ringed pistons very well. Sometimes it's OK, but they generally never seal as well as a new P/C set or last as long. I'd do that kind of engine for myself or my kids, but never for anyone else. So if you can possibly get a new set of P/C's then I'd suggest you do it, lots less work in the end. |

Next question- These are marked STD (standard). Given their age and condition, what brand and type of rings should I buy? Since the cylinders should be honed, should I be looking at a different ring than a STD? |
