: Nick in cylinder wall HELP !!!

I broke a valve in my big block and I found a nick in my #6 cylinder wall( see picture). It falls right betwen the top ring and the middle. I put a new piston with rings in and it doesn't seem to catch, or create a scratch on my rings. Is this a problem that needs to be remedied or can I let it go? What are my options? any suggestions? HELP!!!

I would think that could cause a serious disaster if one of the rings turned on the piston and the edge of the rings line up with that ding at 6,000rpm's. Maybe you can get it sleeved.

:( Run it ;)
If it has no raised edges it will not hurt a thing.
Not worth sleeving in my opinion, the sleeving will do more harm to the adjacent cylinders than that little "divit"

Hey Mike,That's what I was wondering, but I was not sure if the heat and compression would affect it. Apparently you have experience with these types of things being an engine builder? I just hate to invest more time and My wife just loves me to spend more money, LOL, on that old clunker.

Awesome Wolves by the way.

And you should see some of the stuff we have "freshened" that got wounded,,, that ran just fine for the rest of the season & sometimes a number of seasons :rolleyes:
Just call it an "oil retention reservoir",,,,

How thick are the cylinder walls there? Will that eventually crack into the water jacket?

Very thick, it looks to be barely below the deck & is probably .200+ & I highly doubt it will ever be a problem the way it looks in the picture.

Thanks for your expert analysis Mike. I appreciate it. Now I can maybe get it totally together. graemlins/beers.gif

I would run a cylinder hone (bottle brush) through it to be sure there is not a raised part to it.

ya just run some engine treatement with your oil........they all claim to fill nicks and scratches to boost your power.......so you would be ok...........


c'mon guys its a joke...lol...you should be just fine i have have put a few together with what looked like pits where metal just fell out of the cylinder..kinda hard to explain with out pic...but looks like a casting flaw from the factory...but never noticed anything bad.....from the rebuilds.....heck they was that way before the rebuild.......
