Block surface bump at exhaust manifold

I just removed my exhaust manifold and found this bump on the block right where the gasket goes. Is this supposed to be here or should I grind it flush before putting the new manifold on?

You were right- it was a piece of the manifold and gasket. I scraped it off with a razor blade scraper. I should have known it could not have been part of the block, but the color matched so well and it seemed solid when I first tried to scrape it off with a plastic scraper. Thanks for everyones advice.

Flat file and a little time to clean it up. I am a machinist and I don't use power tools on something that I need a flatness requirement on. Makes metal chips more controllable too.

I also would follow the previous tip that you may want to look at the manifold for a chunk missing.

Flat and square more than smooth. ISTR some pictures John Smith had of how he resurfaced that entire sealing face using an end mill and a little Bridgeport. Simple cheap, and effective....

Up and to the left of your red ring it appears that there is some more rust "plate". It probably formed over the course of a few months of exposure to moisture after the gasket had failed. Light tapping with a slag hammer should crack the "plate" so that it falls off. You need to get the mating surface pretty much glass smooth, which of course you can't do with a grinder.

I doubt if it is flash from the casting. That surface is milled on a machine. It never would have passed qc like that. The 'bump' is most likely a piece of the manifold that broke off or a piece of gasket material stuck on. Spray some PB B:ASTER on it for a day then carefully try to see if it will pick off with file or chisel. Grinder is last resort -you don't want to gouge out the port anymore.

[quote="Dave2N1946"] No that should not be there. Grind it off and make the entire mating surface clean and flat.

The surface needs to be both flat and true.

Be careful w/ that grinder!
