Reservoir/ Surge Tank?

[Dunkin]

On the surge tank flange to the manifold is there anything you can do if the flange has a lot of deep corrosion pits in it? Thank you

[Nelson]

You could probably sand blast the pits and fill with epoxy but soldering on a new flange would be best. I would imagine that flange is available. I know they sure seem to leak a lot at that joint.

[Dunkin]

Thanks for response, I think getting a new flange might be a problem. I will check with the radiator shop I have used and see what they can do.

Hi. Did you mean this?

No, it is this.

I would first clean it very well and then would fill all holes with Metal Repair / Rebuilding Compound. The best brand which you can find is Belzona.
Only professional companies have this. I have used it. Of course you can find other brands from retail.

 

[Dunkin]

I am still going to take it to the radiator shop and see what they think. I will look up your recommendation. Thank you

[Nelson]

Another thought. Have the radiator shop take it off and turn it over. I would think the other side is ok.

Take it to your radiator shop and have them clean it with a little acid and then fill the voids with solder. Then you can file it and sand it smooth. I have done this to steel and brass flanges and never had an issue. I would use solder with at least 60% tin content or 95/5 plumbing solder.

I took it there today, and they didn't bring the solder solution up. I have thought of what you suggested also, I might try doing it myself, also there are some epoxy metal compounds out there, that are supposed to work. I will look at turning it over also. Thank you both.  

[Dunkin]

Nelson, I meant to ask if you have turned one over? Thanks

Epoxy metal compounds are ok. Lots of choices at retail like Locktite etc. There is not a lot of pressure. You only need to make sure that the compound can withstand the heat of the water. This is a quite easy job. Clean well and make a flat layer. This way you don't do anything irreversible.

Leo, thank you I think I am going to try the Epoxy Metal first.

Hi Dunkin. Remember to tell results. This will help all of us to solve interesting problems.😊

[Dunkin]

Ok I will. Thanks

[Nelson]

I’ve never turned one over but don’t know why it wouldn’t work. in the old days I would flip starter ring gears to capture the unworn side so I’m up for anything to keep the cars on the road.. I also would try the epoxy first. Sand blasting to get rid of all the rust I believe is critical. I’ve even sand blasted disc brake calipers Bach in the day and epoxied them then sanded and honed. Never had a problem with that either.

[Dunkin]

Ok, thanks

Been looking at JB, there are a bunch of different ones. Thanks

Here is the final fix I hope, I used JB Weld 8265S recommended by them, and a FEL Pro 35562T gasket for small block Chevy. Sanded smooth and is holding up so far. Thanks for all the suggestions.
