Deformed water inlet on block?

[rfakhrai]

Sorry if my terminology isn't correct, I'm learning as I'm going. I have the head off and I'm cleaning the block. I've noticed a deformation on one of the water inlets between cylinders 1 and 2. Maybe it has been like this or maybe I was too aggressive with the gasket scraper.

I ran a shop vac over the hole in case there's a metal fragment in there now, water comes up so it doesn't seem clogged. The head gasket covers the area completely but what does the forum think?

Bump. Would you run it?

Some of these have a small hole, but as you said the gasket covers them completely. Clean up any loose crud and you should be good to go

A carbide edged scraper works well to remove old gasket material and light surface corrosion if you use it correctly ie: keep it at a very shallow angle to the block surface. IME one method is to pull backwards across the surface, but still holding the scraper at a shallow angle. Avoid using "Roloc" or other abrasive disks, they leave a ton of abrasive material behind in every hole and can create high and low spots in the deck.

SS1 (1-1/4" wide blade) and/or SS2 (2" wide blade) The other sizes IME are too narrow, more likely to get caught on and dig into edges of holes/cylinders.

Ok, that was my first thought, but it does look like the cast iron is chipped on this particular port. I think I'll continue to clean it up and send it since the gasket should cover that up.

Yes I have the gearwrench scrapers. It sure is a delicate balance between applying enough force to get the stubborn gasket and carbon buildup off, while not being too aggressive.

@rfakhrai :

Look closer at the webpage in the link above and the photos; the Super Scraper has a sharp carbide edge, much different compared
to standard steel scrapers.
