Painting the intake - Prepping etc. ???

[SHOman24v]

i know, mine looks like yours before it was painted, its just accidently scratching it and misuse, also you cant use carb cleaner to clean it if its painted.... (i like yours painted tho )

Thanks for the compliment!

Use "Engine Degreaser" to clean the motor. That will do the trick! I get mine from AZ, its made by "Gunk".

 

[SHOman24v]

nah gunk is too expensive, its all about wal mart degreaser, its $0.78/can hehehe

Just to clarify: I used duplicolor hi temp clear coat on my white runners.....was yellow inside of 30 days. The paint is fine, no clear coat needed.

you can always touch up the dings you get in the intake.

For those of you who have painted your intakes, about how long did it take you. i am thinking a good weekend and then a few days for the paint to cure? correct me if i am wrong.

after you dissassemble the intake, roughly sand the parts to be painted to give the paint a good surface to bond to. then wipe it down pretty good w/ warm water or some cleaner that doesnt leave a residue. Mask off the areas that should be painted (gasket mating surfaces). then I recommend spraying a light first coat, then come back about 6 minutes later and spray a new coat. i did this for about 6 coats. Try not to wait more than 10 minutes between coats. After the last coat let it sit for a while. then if you want, put it in the oven at about 350 for about 10-15 minutes to cure. I put 2 intake manifold brackets in the oven and 2 of them not in the oven to test the difference. The ones that were in the oven were a little smother. I hit one from the oven and one not together and the one that wasnt in the oven chipped. If you dont want to put in the oven I would recommend letting the paint sit for at least 15 minutes away from dirt/dust (not in garage). Try not to touch the paint too much even if it feels dry for a while. Then you should be good.

So you can do this in about 24 hours I imagine. Depending on how you go about it curing

Not a very close pic but...

A few things I wish I would have done, be more patient and bake some of the parts I didnt and let them sit/cure longer before I installed them. Got that sucker way cleaner before I started painting. Oh well, learn from my mistakes, overall its not too bad. Its worth the $300 something dollars i saved vs powder coating

BTW heres pics of valve covers fresh from the oven

 

[yamahaSHO]

Very NICE!!! I am digging that!! Good job!!!

thanks jason how did you go about the lettering? I tried but with not very good results

Tape around the lettering.... About 1/4" away from it.... Spray paint over the whole area and then immediatly take off the tape and wipe with a rag soaked in paint thinner. You will have to do it a couple times. Make sure the paint on the tanks is cured first. This works like a charm!!! Let me know if I did not explain that well.

How long were the valve covers in the oven and at what heat?

thanks

YamahaSHO,

In that pic it looks like you are using a non stock rubber on the snakes and plenums? What did you use and where to get it?

As far as grinding the casting off the snakes, what did you use to grind it off?

I'm still in debate on the powder coat/paint debate, but want to prep my new spare intake plucked today from the bone yard!

 

[SW SHO]

YamahSHO or anyone else. I have a couple of other questions. Did you or should I remove the buterfiles? How did you paint them without painting the open areas?

Also, where to get replacement gaskets for the buterflies if necessary?

What color is that - gunmetal? I hope mine looks as good as that.

Thanks!

 

[40BelowSummer]

I put them in the oven for about 10-15 minutes depending on the part at about 300-350 degrees.

I didnt paint the butterflies but did remove them to paint the rest of the intake. It looks like Jason painted them though. The butterfly gaskets come with the Intake manifold gasket set.

 

[yamahaSHO]

I have some silicone hoses for the secondaries. Got them at SHO Shop, but if you ask "Off Road SHO", he can tell you where else to get them. I took the vacuum motors off the butterflies and taped off the moving parts and the openings so that I did not paint the butterfly valves.

For grinding off the castings... I used a Dremel with an extension and sanding drums. Works very well.

That "gun metal" is "Cast Iron Coat" from Dupli-Color's Engine Enamel. I buffed it with boat polish after curing, that is why it is so shiny and smooth.

As far as gaskets, I would get the upper intake gasket kit from Fel Pro... You will need them all when you dissassemble the intake.

Good Luck!

This makes me want to paint my 89's intake and after it's all done swap it in the 91...But then I gotta do the valve covers lol and that's a bitch...I might soon though, but ATM don't have the tools.

 

[Sho_Freak]

just got mine done, and on the car before i saw the letter filling way......my black tanks with red runners would look awesome with red filled letters!!!!!!!!!!!DAMN---er dangit, would i be able to do this with a stable hand and a small paintbrush while on the car? and if i take it off to do it, would i be able to put it back on right after puttin it in the oven for a bit?????

thats my creation, lots of sanding, took the castings off, looks great, had about 6 layers on tanks 4 on runners.

 

[SHO92]

You can fill the letters in with a paint brush, its just a little more time consuming. You shouldn't have to put the intake back in the oven. Just go drive around and do lots of 2nd and 3rd gear sprints, the paint will be baked on in no time, and its a lot more fun then watching an intake bake in the oven!

 

[91 SHOplus]

Werd!

 

[40BelowSummer]

In my opinion, as far as the intake goes, put it in the oven. It looks much better. I did both on different parts and there is a difference as far as the shine goes. It also makes it less likely to scratch during installation.

But as far as the letters go, I don't think they need to be baked. They would be fine to "set" on the car.

.........................in summary; Werd!!!
