Was looking real close at cylinder 3 and noticed some light scoring in the cylinder wall.
A few of them you can feel a little with a fingernail.
I did some searching on this forum and found a few other posts with similar scoring, one said he'd split the cases and took everything apart, to find nothing. Put it back together and had thus far put 30-40k on the engine.
Since doing a full blown rebuild is out of the budget for this project I've decided to put it back together and see where I'm at with a compression test.
But I thought I'd post it here anyway so I can update on it later.
Anyone else seen scoring like this and ended up being OK?
Worst case scenario, I get a few season use out of it before a full rebuild or a new engine is needed?

Re: Light scoring in cylinder wall
Found this when I did head gaskets last year. Easily catches a fingernail. I ignored it. Compression’s around 150 in every hole. Slap it back together and forget you ever saw it.

Re: Light scoring in cylinder wall
best to pretend you never saw it. Opening the case is worst than buying an engine. That can wait.

Re: Light scoring in cylinder wall
A piece of crud got in there, probably when a spark plug was changed. I'd ignore it. The cure would be waaaaay worse than the disease.

Your good. This one runs fine after just cleaning the walls with single-edge razor blades.

Re: Light scoring in cylinder wall
The plan was to ignore it anyway, but thank you for the reinforcement
The heads are back on. Re-installing cams and rockers tonight.
