Oh! I didn't know you were cleaning those...

Next time, try Electrolysis.

Suspend the part in a tub of water and 1/4 cup Arm & Hammer washing soda.

Hook the + of a battery charger to some clean scrap iron suspended in the solution.

Hook the - of the battery charger to the part.

Turn on the charger, and walk away.

Come back later and it will be clean, gray, cast iron, ready for header paint.

You know I have tried it in the past and maybe I did something wrong cause although it was working it seemed like it would take years to remove all the rust. Like I said earlier I am not really cleaning the manifolds nor painting them I am going to swap them out for some long tube headers.

Yes sir, you and me both, took me 20 years to discover this gem, and many $$$ spent on wanna be cleaning products, Simple Green, Purple Power, Orange what ever, seems like anything with a color name in it sucks, LOL

frustrated with poor lighting in my garage I finally came up with a quick fix

the problem was that I like to work with the garage door opened, well as you may know when the door is open it cover my florescent light bars so the light don't shine, so solution zip tie a 4 foot light to the hood, done and done

First of all, who am I to give advice, right?! lol, jk

But in case you don't like oil and grime on your (/your wives) garage floor, here's what works for me

I bought one of these 3 foot wide and 50 foot long rolls of 4 mil plastic that painters use (the 4 mil is pretty thick so I like it, it don't tear like the thin ceran wrap junk)

Anytime I work on the truck I roll out about 4 feet of it and use scissors to cut off a piece, then I slide it under the truck, at 3 foot wide it feels nicely between the wheels even with the car not off the ground, after I am done with the job I just fold it up and stick it in the trash

Re: Restoring Rusty - Reading Exhaust Manifold Bolts
 
2 Attachment(s)
looking for the Bolt Whisperer?

I know you read spark plugs but I'm not sure if you can read bolts, exhaust manifold bolts for that matter

anyway, if you don't own one of these magnetic chrome trays I strongly recommend one for storing all your loose nuts and bolts during the disassembly process

so from the rear to the front of the cylinder head, the bolts around #8 were black and wet, the bolts around #6 & #4 were semi black and wet, and the last two bolts around #2 were dry, so what, so what does that mean?

my guess oil from the rocker cover gasket area leaking and seeping down and around the exhaust manifold, but that's just a guess

and removed the air tubes out of this one as well, hope this shows you an extra step to take for those of you guys out there deleting the A.I.R. system by simply removing the outside tubes and plugging the holes with those brass plugs - I believe this will improve exhaust flow and is worth doing

Yes. A form of "lock washer." Once you get the headers on, you'll wish you had those.

Re: Restoring Rusty
 
Looking good. So what is your method with the mineral spirits? Do you spray it on? Wipe on or another method. I'm curious. I am impressed how clean it gets things. Keep on keeping man.

Simple, a can of Mineral Spirits, roll of paper towels, putty knife or flat screw driver and some small cheap brushes (nylon, brass, steel set), fine steel wool (optional).

Step 1 - use putty knife (plastic or metal) to scrape off big pieces of gunk, dirt, or grime. Use plastic one if you don't want to scratch the paint, use metal if you plan on repainting or if the surface can handle it.

Step 2 - Take paper towel fold it into a 3inch by 3 inch square and soak it with the fluid. Then unfold the towel and fold it just once and start wiping. Get the area wet, the first towel is not so much to wipe things off as it is to get the area wet. THROW DIRTY TOWEL AWAY do not reuse.

Step 3 - Use brushes to loosen hard to get off dirt. You can use a spray paint cap/lid as a cup to poor some fluid in to dip your brush. You can exchange brushes for steel wool as you progress as the area gets cleaner.

Step 4 - Get new paper towel, a dry one and wipe away what will come off. THROW DIRTY TOWEL AWAY do not reuse.

Step 5 - Repeat 2-4

important, start in the worst part, the dirties place or the one most difficult to reach and work out of that zone, also take a break, cleaning sucks, walk away or better yet finish the job the next day or the following weekend

I don't know how the pros do it, but this works for me.

got this 20% Off on All Fenders ad in the mail from our local Pick n Pull junk yard so I had no choice but to go pull one

with tax ($4.73), an environmental fee ($4.24), and some BS core charge ($4.99) it came out to be just under $60 bucks, and took me less than an hour to pull it off a green '79 Scottsdale (I was taking my time enjoying a sunny winter day)

Note: not even gonna touch it till summer, I am not painting in the winter ever again

Man, you got that right! Most of that stuff is less effective than dish-washing soap and hot water!

Thank goodness we can still buy Gunk Engine Degreaser. I'll have to try mineral spirits, too.

hey bro, you're in Cali do you want this one, I will sell it to you for what I paid for it plus I will go pull the other one for you if it helps, I can always get another fender and if it saves you painting yours its a win win, I can even drive it out half way to your house

OK got her buttoned up whilst listening to the Colts handle the Bengals on the radio

not perfect, but much cleaner, even wire brushed the manifold bolts, wish I knew how to keep them from rusting again cause painting bolts hasn't worked for me, the paint just twists right off as I install them, also wish some of these pictures came out better

You need to clear those bolts or paint them or something, they rust 10x quicker after being cleaned up w/a wire wheel.

Looks better. Did you install new valve cover gaskets?

Yes back in October when I painted the valve covers. I special ordered these black rubber Mr. Gasket ones. This time I did not take them off although I fully planned on it cause I thought my oil leak was seeping out from the back of the passenger side valve cover, but I don't think that's the case. Now I am leaning towards the rear main seal as being the culprit as my bell housing is full of black oil and grime, not nice.

I need to treat them for sure, still looking for a proper solution since I'm not a big fan of paint on the threads and I strip the paint off the heads as soon as I install them, so need something more better, like Eastwoods blackening dip kit.

Re: Restoring Rusty
 
New bolts are zinc coated in most cases. While they may be a little ugly after the decades, when you strip all the zinc off they get rusty fast like any unpainted steel.

Yeah, I should have explained a little. I helped a friend freshen up the engine bay in a 78 Corvette he's had a loooong time and we did the same thing with all the bolts for the accessory brackets. Three months later they looked like crap and he had to redo them. Another member here found someone local to him that does the zinc plating, apparently it's fairly cheap to do. You might not care to go that far on this truck but I'd at least hit them with satin black or maybe header paint if you have some. Those will rust like they are.

Re: Restoring Rusty - TRANSMISSION CONTROL SPARK SYSTEM
 
I decided I would clean up and decluter the engine bay a bit before bolting on my new intake, carb, and air cleaner, that way I won't get any of that old electrical tape glue and grime on the new shiny bits

so if I may borrow a term from the Import Crowd, I will be "deleting" the Transmission Controlled Spark System, TCS

say what?

The Transmission Controlled Spark System is used on all 10 Series vehicles, C-K20 suburban, G20 Series and G30 Sportvans when equipped with a manual transmission.

lucky me

so what does the TCS do?

Control of exhaust emitted by vehicles using the eight cylinder engines, is accomplished by eliminating ignition vaccum advance when the vehicle is operating in reverse, neutral or low forward gears

sounds great - lets get rid of it

TCS Time Relay, this bad boy hides behind the brake booster on the fire wall, I am just going to unscrew it, (one bolt) and leave it plugged in to the wiring harness which will be yanked out anyways

Re: Restoring Rusty - TCS Temperature Switch
 
1 Attachment(s)
next is the TCS Temperature Switch, this redundant temperature switch lives in the right cylinder head between the #6 and #8 exhaust ports (unlike it's much more useful cousin in the left cylinder head between #1 and #2 exhaust ports)

for now I will just unplug the single green wire from it and leave the temp switch in the head, sometime later on when I feel like draining the coolant (again) I will replace it with a nicer plug
