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 |

and this is just to compare how the passenger side exhaust manifold area looked like when I got the truck and how it looks today, a bit of improvement wouldn't you say

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

Re: Restoring Rusty
Looks better. Did you install new valve cover gaskets?

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.

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 |
Re: Restoring Rusty - TCS Time Relay

first we introduce the five usual suspects
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

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 |

the TCS Vacuum Advance Solenoid sits in the front right of the intake manifold, next to the oil filler cap in the photos, both pictures show the same solenoid just from different angles as it is buried behind the heater core hoses

the fourth component the TCS Idle Stop Solenoid attaches to the front of the carburetor, shiny bit in the photos, and is there to prevent dieseling

Re: Restoring Rusty - TCS Transmission Switch

the fifth and the final component is the TCS Transmission Switch located on the lower driver side of the transmission, I plan just to unplug it and leave it there
mine is grimmy but it should look something like this |
Re: Restoring Rusty
Thanks for the info!

Re: Restoring Rusty - Removing the TCS Wiring Harness
2 Attachment(s)
Four of the five Transcmission Controlled Spark System components (the Idle Stop Solenoid being the exception) hang off of the same wiring harness, which plugs in to a single brown wire on the firewall leading to the fuse block.
I was able to unplug the harness from all of them except for the Transmission Switch. It is simply impossible to see how it plugs in, and you have to feel up in there, so I am still unable to disconnect the one last final wire to be able to completely remove this wiring harness. |

The Idle Stop Solenoid connects to the fuse block using its own single brown wire

I am one of those people who needs to know where things go, wants to know where they go and how they work, so i had to gently unwrap the crusty 40 year old wiring harness.

I just like to see where these wires go, so here is the fuse block side getting unwrapped

check out that Fusible Link, looks good right, wait till I unwrap the harness, all of a sudden it doesn't look so good
