Protecting New Aluminum Intake Manifold

Hi Everyone. So I have a leak from the the rear of my intake manifold. This'll be the second time I've replaced it since building the engine seven years ago. The last time I omitted the rubber gasket in the front and rear and used the high-quality sealant. Since I have to replace the gasket yet again, I've decided to put a new Edlebrock Air Gap manifold on. The finish is satin. I'm wondering if it would be benifitial to apply a clear heat resistant paint to keep it looking good or if this is simply a waste of time. Any thoughts on gaskets and sealants would be welcome as well. Thanks!

Re: Protecting New Aluminum Intake Manifold

Any clear coat you put on will yellow and look like hell, then you will have to hand scrub it off.

Keep it clean, if you get something on it, brake clean is your friend. When the engine is warm and off, I have sprayed brake cleaner around the inside are bolt holes that are hard to clean, it boils and you stick a paper shop towel and it sucks it up, be careful, as it is hot.

I like the permatex ultra black, but it is visible, the grey looks better. The right stuff in the spray cheese can sticks like nothing else, but am told that it has air bubbles in it and to buy the chaulk gun size, probably 100 bucks knowing them. The key is to measure how thick your beads will need to be before you start, dry fit with side gaskets in place. I would drop the intake on and barely snug the bolts, wait on hour and then torque to spec. I like to wipe off the excess, others either leave it or cut it off with a blade once dried

Re: Protecting New Aluminum Intake Manifold

I used a moisture cured polyurethane about 1985 and Mostly still looks good. Fuel drips will stain and yellow it. Newer products may be better

Re: Protecting New Aluminum Intake Manifold

On my BBC for intake manifold gaskets I would use Fel-Pro 1211. For a sealer I use Permatex Ultra Black. I use Permatex® Super Weatherstrip Adhesive on the cork end seals and let dry. I use the Ultra Black on the front and rear cork end seals where the ends meet the head. These sealers work great because it was seven years before I pulled the engine for an overhaul. I had to use a screwdriver to break the seal. I use cork valve cover gaskets with a sealer called Indian Head Shellac and it took a couple of whacks with a rubber mallet to break the seal.

Re: Protecting New Aluminum Intake Manifold

I think there might be a clear powdercoat now.? I was going to check into it next time I drop some parts of to be coated. I'm going back and forth on whether tp coat it clear if available or a natural aluminum color, or black.
If I didn't already have my new air gap,I'd have ordered the black powdercoated one from the start. I do know that I will have it coated to make cleaning easier, since I never liked scrubbing around the bolts to clean the fuel/oil/gunk stains.

Thanks for all the great response. I did debate getting the endura shine one and am still not sure I made the right choice not getting it. It seems polished aluminum looks great for a while, then gets scratched easily or pitted.

John, The Endura Shine finish will yellow if/when fuel gets on it for any length of time. The Endura Shine is if I remember correctly a two coat finish system with the last/top coat being a clear coat. I did a bunch of research/reading up on others experiences before ordering my last intake and ended up deciding to go with a polished one and then just take care of it as best I can.

Re: Protecting New Aluminum Intake Manifold

I used Eastwood Diamond Clear on my natural valve covers. I was going to use the same product on my Vic Jr. intake, but I didn't get around to it over the winter. If you do a google search, you'll find people say it doesn't yellow, as well as other people that say it will yellow with fuel. I'm fuel injected directly into the base of my runners, so I'm not as worried about fuel spills from a carb.

Re: Protecting New Aluminum Intake Manifold

Im looking into the product by Eastwood and where it can be purchased. My guess would be that no matter the product, just 2-3 thin coats to keep the depth of the product to a minimum. Also looking into the other finishes that the manifold comes in. Wish this wasn't ny day off and that I wasn't all set to do this today.

Re: Protecting New Aluminum Intake Manifold

I had the outside of my aluminum intake coated by the same company that coated my headers. It seems to be holding up fairly well and is impervious to the heat on top of the motor. It's a bit shinier than I expected so I would probably go for a slightly duller finish if that option is available. It definitely is better than a fuel-stained, grease-soaked aluminum casting.

I think I got it through Jegs, but you can find it on Amazon as well. I don't know if you can find it locally though.

Re: Protecting New Aluminum Intake Manifold

I had my brand new Victor Jr, timing chain cover, valve covers, breather caps, and used Hooker Super Comp headers done by a Company called Thermal Tech Coatings here: Thermal Tech Coatings Inc 312 East Poythress St # A Hopewell, VA 23860
Phone: (804) 452-0263
Web: Thermaltechcoatings.com I had it all done a silver color and everything looked good. Everything but the headers is still on the engine. Once in a while if I feel energetic I will polish everything with some Mothers Billet Aluminum Polish and it brings back the shine.

NOT TRUE!
I went to the dollar store and bought their clear coat and mine still looks great from 3 years ago

Re: Protecting New Aluminum Intake Manifold

The clear sprays change the look of the intake regardless of the yellowing issue. I had jerry tumble an intake and it looked nice, now I glass bead it lightly and then very lightly rub it with ooo steel wool to take the powdery blasted look away, if you rub to hard you will get a shiney spot. It looks the closest to the original finish that I have found. The steel wool closes up the pours in the freshly blasted intake.

First off thanks for the great responses. There certainly is a lot of differing opinions and that's great. So today I took the intake off, cleaned everything up. I was going to put the intake on with just the bare satin finish on it, and then at the minute, decided to return it and get the one with the Endura Shine finish on it. Tough decision especially with all the great feedback and advice. Not to mention, tomorrow just happens to be my bday and instead of taking it for a new cruise, all I can do is look at it. My feeling is for the $110 additional, it has the best chance of looking halfway decent over the years to come. Yes, I will still have to be careful with it. And if I stuck with the one I purchased, I would have to do something to protect it regardless. At least if there is an early failure of the finish on the Endura one, Edelbrock may have some liability to make good on it.
