Scratch on fresh engine deck - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So unfortunately while taking my engine back from the machine shop I scratched the engine surface. Bottom end is built, and it was decked. I would normally send it with copper spray, but I plan on using a Tomei head gasket which is precoated. Do you guys think this will cause an issue? It does catch on your nail.

It doesn't protrude into a passage so you should be fine.

I'm assuming the gasket is multi layer as well, so you should as mentioned, be fine.

Thanks everyone, should i try and debur it all or just install the gasket normal procedure.

You can go ahead and buff it down with some sand paper and then use a scotch brite pad to help smooth it out.

I scratched my block near cylinder 4 between the cylinder and the water jacket. I was really concerned about it but I've got her back together and she's sealed. I didn't sand it or try to smooth it out, I was even more worried about deforming the surface of the block. For what it's worth I'm using a Tomei headgasket and I used copper spray also.

That's for the oil draining back into the block from the head so it isn't pressurized. It probably won't leak but if you want put a dab of ultra grey on it right before you bolt the head down similar to what you do at the front cover.
