Thanks for the thoughts.
Yes, it's on the fresh water side.
The owner would prefer new if possible. I thought about having it welded. If had luck with getting cast welded before. I'm a little concerned about how thin it may be. Looks like it may be starting to go in other places. I'll go ahead, and pull it off, and see how it looks from inside. I would think if i had to go the epoxy route, I will try and path for the inside as well as out.
I'm surprised Google came up with very little for Covington parts
Yes, bead blast the inside and cloth reinforce an epoxy patch on the inside. I have a few projects out there still running like this. It has to have pretty grey metal and not a dot or spec of rust. Apply epoxy straight from the bead blaster booth.
Sadly, I agree Covington web leads are near gone, vs many moons ago, lots of data and parts.
Here is what Penske was complaining about when he bought in and changed Detroit. To many shops taking away from the good Detroit name. He was worried about the future,, like this..
Who can the owners be upset with? Covington or DDC? Do they understand the difference? Not many do.
It's ancient history now, but when Penske took over DDC, There were warranty wars started and DDC won most.
It is good for the customer to find a good tech that understands these issues and can keep those sweet Detroits running. That tech is worth his (her) weight in gold when they can re-invent the wheel and she keeps running.
Again, who's problem is this? Not the techs, but who can be the well paid hero? Only the better tech.
Owners need to understand this also. Great engine. I'm a big fan. The marine conversion does matter. The tech that keeps you running??? Find the best and pay him well. The original old grey hairs are sadly buried or near EOL. God bless them.
