Got a good deal on this used Offy 360 EquaFlo Intake, now I see why. I'm debating whether or not to take the chance and use it. Look at the bottom right of the picture at the water passage portIf you can't see it to well click on the link for the bigger image Offy360 and then you can see what my concern is. I'd like to thank Johnpro for hosting my pict.

Brett,

You could probably get a good seal on it, but may also get accelerated corrosion in that area due to kind of a dead spot for flow. You might take it to a machine shop and see how much they would charge to build up the lip area in that one spot, then dress it off. Then you can determine if it's worth it to repair. Good Luck!

I think I'm missing something ... that intake looks perfectly fine to me. It looks used, but perfectly fine. If we're talking about the corosion at the rear water jacket block offs, any intake with a couple thousand miles on it will have that, particularly aluminum ones. I wouldn't hesitate to use it ... so am I missing something else?

This is sort of a backyard repair but works very well!

Get rid of all the corrosion by either bead blasting or wire brush, mix up some J.B. Weld and smear it on...After it has hardened, sand flat with a sanding block and something like 80 or 120 grit paper.

Wow, I didn't think this got posted last night, Bob was in the middle of an upgrade so I reposted it. John, look at the bottom right of the pict, not the block off what where the coolant flows into the cylinder heads.

Looks like it would be OK to me, but to be sure you'd want to lay an intake gasket over it and see it if the gasket covers the opening adequately. This is normal stuff to see on vintage aluminum parts, intakes in particular. The older formulations of antifreeze were pretty hard on aluminum. I believe a little extra sealer around the water passage should make it no problem. Much as I hate to say it. RTV silicone should work quite well even if the gasket doesn't quite cover it. (I just don't like RTV very much) Just be sure not to use RTV around the actual intake ports and not to overdo it's application. Exposure to fuel/air mixture over time turns RTV into something resembling what's hanging out of your 3 year old nephew's nose. Nasty and useless. As long as you use it in moderation around only the water (or oil) passages it works fine though. I like Permatex "Aviation grade" liquid sealer for most stuff, but it doesn't do well with filling larger voids, nor is it meant to.

Didn't see the upside but if it is a divided single plenum as I quess, there are better dual plane designs available. Equaflow is kind of funny if you think the firing order, usually the dual planes suck evenly from both plenum sides, whereas with divided plenum you have 3 to 1 per bank. Not that I know really but I just wonder if the fuel distribution could be optimal. If it is a 360 single plenum without divider you would have the usual loss of low-rpm torque. There is a reason why these old single planes are cheap at swap meets.
