I have the master soaking in vinger/dish soap/hot water with some baking soda sprinkled on top then I put a bag over it. Tomorrow I'll attack it with a wire wheel then prime and paint👍

I have a can of cast blast and I ordered paint for the booster. Does anyone have a photo for reference of what it should look like? Should I polish the mc cap or is supposed to be kinda dull?

I believe the red electrical connection is a resistor for the blower motor?

I'll definitely use foil. I think I have in the past. I happened to have tape and only a little foil. If I used it the wife would definitely notice and have something new to complain about 😔 😆

You're a big boy; buy your own foil.

Yes, that is the blower motor resistor.

Yup!

The red blower motor resistor is not stock. Stock would have been black.

Red is the correct color for the A/C blower motor resistor. The black ones are parts store replacements.

?? Interesting. First red I’ve ever seen.

I don’t doubt you. First red OEM I’ve seen. Thought the red ones were replacement. Thanks for that.

Next time I don't splurge on tape I'll spend my "allowance" on foil....after I pay all the bills (I'm a big boy now). Should this mc cap get painted to match the booster or just cleaned up?

They are usually covered in black gunk, grease, and soot from 40 or so years under the hood and can appear black until cleaning. Once you wipe them off, you'll see the red. If the hood was left open to a lot of sun exposure, they can also fade to light pink over time.

That blower motor resistor is old school and I love it. Today I bet they use FETs on a printed circuit board, probably not even discreet components but one or two pins of a more complex microprocessor chip.

Almost ready for paint! Should the cap match the booster? Black lines?

Thanks

I'm starting to like the idea of painting the engine the correct bronze....does any one have links or brands with pictures? There's a lot of different shades!

If you want to go bronze I would just pick a shade you like the best as there were a lot of variations from the factory according to this thread.

I have no proof of this but he always seemed to be a gentleman in the know so I believed him. Maybe a retired Olds assembly line worker could shed some light on it?

I have some bronze from Supercars that goes on real light (almost a champagne gold) but darkens considerably as engine heat bakes it. After some running time it looks pretty good to me!

The other thing to keep in mind is that the shade you get from a metallic paint is heavily dependent on the application technique. If you use the normal method of applying multiple thin coats, the result will usually be a lighter than desired color because the metallics are close to the surface. When Olds painted these engines at the factory, they didn't care about runs or finish, only about getting coverage with the minimum amount of time and labor. The result was a single wet coat that buried the metallics in the paint and thus produced a darker shade (along with runs).

And...I suspect they were nearly flash dried in a baking/heating enclosure as they rolled through the assembly?

Thanks Joe and chief. It's supposed to be crappy weather here until monday. I have two cans of bronze engine paint from the parts plc and some high heat enamel (grey) primer and some high heat clear. I hope the paint is still good I bought it a few years ago and it's been sitting since. Same with the cast blast and the grey manifold paint. I'll probably be polishing parts until the sun comes back out. I got this master pretty much striped down. I found some CAD paint on eBay. It looks alright but was wondering what others have used. I don't want to get it re plated. Also we're the bake lines black ?

Thanks

Insert off-topic text here:>>>I viewed a video somewhere (probably YouTube) indicating Fisher Body went through ~23,000,000 (million) gallons of paint per year. I assume this doesn't involve engine paint.

I mean you can use aluminum foil to mask-off areas, but painter's plastic is very easy to work with and is less costly; although, Al foil has its merits in select areas. You can buy a 9'x12' plastic drop cloth for $3.50 or rolls of painter's plastic.

Thanks Chief I usually have a roll of plastic laying around or a roll of masking paper. I think I have some paper for when I do the fire wall or brake booster. And a bit of foil (don't tell the wife). The other day I used random old towels to mask off a tire. It worked.

I think I have a couple of fitted sheets we don't need 🤫

My camera.phone will only take b/w,

​So I lightly sanded and really cleaned things up
I only came across some very light surface rust. After I prepped it I sprayed this to help get ready for paint!
My question is...
Can I top coat it with por15 (chassis black? The can says epoxy paints are fine but idk what por 15 is...can you help?

Thanks

Is the wiper motor aluminum?
im cleaning it up but don't want it to rust..

Is there a rubber typeflap that's goes on the A.C's hard aluminum U line? It looks like there was something there 🤔
Thanks

The parts place bronze (after some vht enamel primer) and some por15 (chassis black) on the fire wall and frame...the engine paint (rattle can) was 8+ years old and worked perfectly!
now for the oil cap. Is supposed to be color matched to the engine?

Thanks!



Parts Place Restoration shop bronze....after high teml vht primer.


And the valve covers were swapped (fleming442)

It's called Expansion Valve Tacky Tape and I bought mine from Old Air Products PN 21-0617. Here's a link:
