Horizontal Score In Cylinder Wall??
Horizontal Score In Cylinder Wall?? Just pull the heads off my 80K LQ4. Purchased engine over a year ago and it has sat until this point. I've never fired the engine so I don't know what compression was prior. I can definitely feel the score when I run my finger nail through it but it doesn't "Catch". All the other cylinders look good with cross thatches visible.
I normally have seen vertical scratches. Any idea what would cause this?Should I take this to a machine shop to look over?

Should I be not as concerned since the scratch is horizontal and not vertical?

Brett Foote Thanks Guys. I think I will just button it up and see what happens. At the very least I want to get the car running and off to the bodyshop. If I don't lose compression then its a plus.
