No damage to my engine. Just torn engine down again, got the rods turned and then rebuilt it. But there is no guarantee that is the problem. You need to get the guys from the machine shop or an expert to have a look at it and hear it before you tear it down again. Do not start it up again until an expert is on site. I fixed mine after it was on the road for 1000 miles. Rings seated fine.
Get a engine rebuilding book and the Jim Hand book before you reassemble. When the shop only does the short block how much time do you think they spend on checking clearances etc.?
