Technical How can I fix this intake ?

You could get some gasket material & make your own intake gaskets with the unneeded ports blocked off .

 

I have a few of these and was planning using them with gasket as long as the surface differences doesn't look to bad. On the chevys the little plate fits into the port where this will be flat across when filled.

Seen this to late, I ordered the ''ALL CRAFTS' Professional Epoxy" this afternoon and another set of carbide bits for the Dremel tool to help clean it up.

 

Okay I hope it works for you

 

Got it cleaned out and ready for epoxy

 

Looks like dental work.....

 

I had a pick in there and that's all I could think about
Nothing left to do but let it harden, sand it and see how it turned out.

 

Shining a light behind a straightedge it looks really close but should I be worried about those couple of divits ?
My concern is the epoxy adhering to itself if I do try and fill them. I realize that they are not really in the gasket sealing area and pretty much wouldn't make a difference in function and you're not going to see it once the manifold is installed but it'd look better filled in ha ha ha

 

looks good to me....

 

Yep! Looks way better than it did...

 

Run it! I was wondering when I first saw this thread...why is he going through so much trouble for a throwaway intake? But fixing stuff because we can is where its at...and this repair might inspire other guys to fix theirs, instead of tossing an otherwise good part.....good job on the repair!

 

If it was my manifold I would check the front water runner area for signs of similar corrosion inside the runner area.

 

Looks great in there, oddly and weirdly those two spots are the only damage on the whole intake.

 

I have an Edelbrock SBC intake that was just like it .
The only places were just like yours,,,,,everywhere else was perfect

 

If you decide to vapor blast it to clean the topside up, be sure to tell them not to clean that area.

 

Probably not a real big deal, but I might have thought about an "aluminum" filled epoxy product, just to better match the manifold's thermal expansion.

 

Solid gaskets in that area, with some brass shim stock, would be a smart move, at least I would think so anyways. Good luck with the repair work.

We used to fix aluminum helicopter parts by burning out the corrosion with metal prep after a light blast. We then used a permatex product called metal set or something close to it. Smells like the old Deacon plastic steel. Machines pretty well and will glue in thread repair inserts to where you can torque parts to them.

 

You can also use anti cavitation additive to your radiator. We use in all our 7.3 diesel’s to prevent this. I have been using it on all my equipment.

 

You can re-epoxy if you scratch/put some tooth in the low spots... Same as doing mud/glass work...

 

Looks good to Me Phil. I'm sure you'll be fine.
