The Stovebolt Site Forums The Shop Area Engine Shop Powder coating intake manifold

Would powdercoating an intake manifold be a good idea? 58 235. Dave

I'm not sure if they make any high temp powder coatings yet. You could try a ceramic coating for both intake and exhaust.

Jeff

Powder coating works just fine on intakes. I've seen some great looking silver and even the chrome coating if your into bling. Go for it.

Do they make a chorme look alike in powdercoat? Dave

I have mine coated, did it myself using a Eastwood home unit and old oven. My dads engine has everything powered except the block and heads (Pontiac V8) and has held up well for a many years. Engines only get to 200 degrees or so, powder cures at 400, so it holds up just fine. Dark colors hold better then light. I had mine Chrome Silver which looked good, but seeping gas discolored it. I went with black this time and have had no problems.

Joe

Well yeah, Homer. I've seen two different finishes. Not the genuine article but not bad either. Bare in mind that chrome finishing is a polish first and plate second so smoothing your manifold will enhance the PC finsh, paint or chrome choice.

Check out this link to my favourite tractor page. The fellow in the picture has an exhaust stack done in what he refers to as a silver high temp powder coat. http://www.ytmag.com/cgi-bin/viewit.cgi?bd=oliver&th=151655

No luck

I'll see if I can post and get some info for you on the Oliver page. What did you think of the pictures of the exhaust? I thought it looked chromed.

Yes, I think it looks real nice. I was also thinking of doing that to the front bumper of my truck instead of the chrome Bumper, I think it would be much cheaper and I wouldn't have the high shipping cost. I have a 41 Allis Chalmers WC also. Dave

Here is some high heat powder coating info I got on the Oliver page.

Both your 250 and your dads v8 have manifolds that do not connect to each other. I would be concerned about the heat transference through the metal bolted together. Also, exhaust manifolds get a hell of a lot hotter than 200 F degrees.

That would be my concern.

Jeff

Super55,

That is ceramic coating. That will hold up with the excessive heat.

Jeff

Exhaust and intake are two different animals. Nothing but the ceramic coatings will stay bright and shiny on a exhaust manifold. The questions was about intakes, so I stand by my answer, powder coating is a good choice. And for the record, the attaching points of intake to exhaust are still looking just as good as the day I put them together.

!

Joe

My concern is can the powdercoating take the heat of being bolted right up to the exhaust manifold in a standard 235 configuration? I'm not familiar with the hookup you are using on your engine. Dave

Joe H, looking through your pics it doesn't appear that the intake and exhaust manifold are bolted together. Are they?

If the intake is bolted to the exhaust than heat will transfer from one to the other. If the exhaust reaches 600 F degrees than the intake will also reach a very hot temp espescially where they bolt together.

This is the question I'm trying to bring up. Will the heat transference from a hot exhaust manifold affect the intake it is bolted to if powder coated. Where the manifold are not bolted together there would only be reflected heat absorption which is much less than heat transference through solid metal to metal contact.

Jeff

The pictures are old ones on this site, what I have now is bolted together. What is the out come you are looking for? Gloss, smoothness, or durability, any one of which paint will do the same thing. I coated mine because of the finish quality, kinda reminds me of the old ceramic finishes on engines from the teens. Powder will hold up just as well as paint will, both have about the same heat rating.

Joe

Thanks Joe, that's good to know!

Jeff

Homer52...I read your thinking that it wouldn't cost as much as chrome to do your bumper. That MAY be true if your powder coater has the chrome powder of your choice in stock. If he must buy some it is pretty darn pricey and the shelf life isn't too good so he may insist you buy the entire ammount he must order. My guy did and it ain't cheap.

Hey Super 55!
Just seen your post. I am working on putting 270 in my truck and hydraulics in the RC 77. Wishing you and yours a Blessed Christmas and great New Year!

Same to you, we're going to get booted off the thread for getting off topic, but it's Christmas! Check out the stovebolt spotting I put up that Oliver truck.
