They get corrosion there for some reason.
Id pull it and try to epoxy it prior to replacement.

If memory serves, its either made of pot metal or aluminum. You might be able to braze, but ive used epoxy before and it lasted at least 3yrs.
Just my experience.

It's Aluminum and it corrodes due to the different metals. If you use a good anti-freeze it helps slow down the corrosion.
Also if you take off the cover, sand-blast it clean and paint it with a "aluminum etching" paint and then a good high gloss enamel it will last for decades without any trouble.

As Chris said maybe some JB weld to fill in the pits around the gasket edge. If there are deep pits in the aluminum with that white corrosion clean the housing well with solvent to remove all grease /oil. Then use apple cider vinegar on the pits and it will eat out the corrosion but not hurt the aluminum. Water flush and dry when all the pits are cleaned out.This will help the JB weld stick well and clean out the pits and stop the corrosion. Then use the JB weld and sand down flat or apply to a flat edge for the gasket.
The apple cider vinegar works real well. Had a friend with an outboard motor that was getting pitted bad and we cleaned it washed it with the vinegar and painted it and it has lasted years.

That's a good idea with the "JB weld" . I didn't think about filling in the pits for the present problem, just how to protect it for the future.

You could also drill out the hole and tap it with a NPT tap and use a stainless steel NPT plug. That would fix it pretty good. I would remove it and clean it up like I mentioned earlier, and don't forget the "etching" paint.

I thought about the chips, that's why I said to remove it, clean it and drill it out. Then paint it with a good etching paint and gloss paint. The thickness is around 3/16" I believe.

Problem might be if one hole popped up then it won't be long before another strikes. If a replacement could be had myself replace.

Very true. Finding a replacement for a reasonable price might be difficult though.
As a side note "Floridianson" , I now have my brother after me to complete the "Great Alaskan Adventure" !!! A guy cannot get a break around here !!! He's right of course. My son will soon be to old to want to go on a adventure with his old man.
He turns 15 next month. He's my only child from a second marriage. He used to hate it when I dropped him off to elementary school and the kids would ask if I was his Grandpa.

Having taken this apart before, it’s not that bad. You’ll need two gaskets. One for the “access cover” to oil cooler and one for the oil cooler to the oil to cooler “housing”. You will have some spillage of both oil and coolant, have a bucket or big drain on ready to catch what you can.
Probably preaching to the choir but....Remember, the day before yours started leaking you could have sold it as a “good take out.” Every used part is going to have some degree of wear. Clean, prep and paint as Rusty said previously to minimize the chance of having to possibly do this again in the not so distant future.
