So I'm not going to mention which youtuber said it because I'm not throwing dirt at anyone but I recently watched a video and it was mentioned that you can more often than not, reuse your old cast iron rings.
This actually makes sense in certain conditions like my 318 engine. It was running, I junked the car around it and now I'm cleaning it up for re use in another car.
I am going to hone but the aforementioned video also recommended honing but reusing the cast rings and only after a good inspection and if they appear square to the bore, as verified by a test with light.
Is this an old timers trick that really works or should I stop watching YouTube?
